The next two days were a blur for Kenny. After the first night of Lilah’s visit Kenny was so exhausted from the nearly non-stop sexual activities with her and Cindy that he called out sick from work. The two slime girls took pity on him (to a point) on the last day before their mother arrived, letting him relax and get some much-needed sleep before she arrived the following day. As much as they both wanted to have sex with him as much as possible they knew he would need his energy for his encounter with their mother, so they reluctantly gave him the night off.

Kenny slept until nearly eleven AM the following morning, and he had only been up and about for an hour before the front doorbell rang.

“She’s here!” the two girls said simultaneously, looking at each other as they sat on the couch. They were both dressed for the first time in two days, both of them wearing the same tight shirts and shorts as they had before. Kenny was wearing a t-shirt and a pair of khaki shorts, an old pair of boat shoes on his feet, and as the two slime girls ran past him to get to the door he had a feeling he wasn’t going to be wearing his clothes much longer.

The screams of delight were loud when Cindy opened the front door, and after a few moments of happy chatting the three slime girls came into the living room where Kenny was sitting in the center of the couch. He had a feeling that was the place he was going to end up eventually, so he went ahead and sat there. The only thing he wondered about was what color Cindy’s mom was going to be, and as soon as the three of them appeared in the entrance to the living room his question was answered.

She was blue, just like Cindy. She was also just as tall as her daughters and had the same kind of body, with one difference – her tits were bigger than her daughter’s. Not much, maybe a cup size and a half, but definitely bigger. All three slime girls were grinning from ear to ear as they stood in the doorway, with the mom in the middle and a daughter on either side, their arms around each other’s waist.

“Kenny, this is my mom, Clarice; Mom, this is Kenny, my boyfriend!” Cindy said proudly.

“So this is the human male I’ve heard so much about!” Clarice said, grinning broadly. She slipped her arms from around her daughters’ waists and walked over to where Kenny sat; he got up as she approached and extended his hand, smiling as he spoke.

“It’s a pleasure to finally meet you, Clarice,” he said, looking up at her. She was just as tall as her daughters, so her huge breasts were almost level with his face as she stood in front of him.

“Oh, no, a simple handshake won’t do!” she said, still grinning. “C’mere, you!” she said as she reached out and grabbed him by the upper arms. Then she pulled him to her and wrapped her strong arms around him, holding him close and hugging him firmly. Her huge breasts pressed against his shoulders and the sides of his head, nearly burying his face between them. The only reason he wasn’t completely buried was because the shirt she was wearing – a tank top just like the ones her daughters were wearing – kept them in check. But they still swallowed him up, and he had a feeling that before the day was done he was going to have his whole head encased in them after she merged them into one around it. But in the meantime he put his arms around her and hugged her back. She held him there for a few moments and then released him, stepping back to look at him.

“He’s just as handsome as you said he was, Cindy,” Clarice said, looking him up and down.

“Wait until you see him naked!” Cindy said, grinning.

“Wait until you see his penis!” Lilah said, also grinning.

“Oh, I’m looking forward to both!” Clarice said, looking down at Kenny and smiling like the cat who was about to eat the canary. “I’ve heard so much about you, Kenny, and I just can’t wait to experience you myself!” she said, bending over and putting her hands on her knees to bring her face down level with his and inches away, her mammoth slime breasts hanging down in front of her.

“We’re going to have so much fun together!” she whispered, looking into his eyes with a mischievous smile on her blue face. “I’m going to drain you dry! By the time I’m done with you, your testicles are going to look like a couple of big raisins!” she said, chuckling. Then, without warning, Clarice reached out and grabbed Kenny by the waist, picking him up and slinging him over her shoulder.

“HEY!” Kenny cried out in surprise as Clarice turned and walked down the hallway towards where she figured the bedroom was.

“Oh, yeah, honey, did I tell you that Mom has a bigger sex drive than I do?” Cindy called out to him, grinning as she watched her mother carrying her boyfriend down the hallway.

“Yeah, you mentioned something like that,” he said, looking up at her and smiling.

“Did she also tell you that Mom was a lot more aggressive than we are?” Lilah added, also grinning.

“Yes, she did,” Kenny said as Clarice turned the corner into their bedroom. When they disappeared from view Lilah looked over at Cindy and spoke, a big smile on her face.

“So what do you want to do for the next four or five hours? Because if I know Mom like I think I do, that’s about how long it’s going to take for her to be finished with him,” she said.

“This time, anyway,” Cindy replied, also smiling. “C’mon, let’s go see what’s on TV!” she said, slipping her arm through Lilah’s and walking into the living room towards the couch.

As soon as she walked into the bedroom Clarice walked over to the king-size bed and unceremoniously dumped Kenny onto the bed.

“Oof!” Kenny grunted as he hit the bed, bouncing on the mattress. Before he could do anything else Clarice was on him, grabbing at his clothes and quickly stripping him. Then she stood up and quickly slipped out of her own clothes, her massive blue breasts with their equally massive areolas and nipples swaying heavily as she moved. She looked down at Kenny’s cock as he lay on the bed, grinning as she stood with her hands on her hips.

“Cindy wasn’t kidding, was she?” she said, looking up at him for a moment before looking down at his cock again. “You really do have a big penis!” she said, her grin getting bigger. “And I’ll bet you produce buckets of sperm when you cum, don’t you?” she said, looking up at him again.

“Thanks to the chemical your body produces, yes,” Kenny said, sitting up on his elbows, trying hard not to stare at her massive blue breasts but failing miserably.

“Well, we’ll soon see about that!” Clarice said. With that she quickly climbed onto the bed and fell on top of Kenny, nearly smothering him with her mammoth, heavy breasts and pinning him to the mattress with the weight of her slime body.

“OOOOF!” Kenny grunted as Clarice fell on him. Her body was smooth and slick on his, and he could feel his cock beginning to get hard as the chemical in her skin began to take effect. The scent of strawberries began to fill the room, a sure sign that Clarice was sexually aroused. She slid down his body just enough to bring her face level with his, sliding her huge, heavy breasts down from his face and shoulders to his chest.

“First things first,” she said, her voice soft and sultry as she looked at Kenny, her yellow eyes sparkling. Then she kissed him, her lips full and soft, her plump tongue slipping into his mouth to find his own. She pressed her hips down against him, moaning softly as she felt his cock growing beneath her. Kenny put his arms around her and held her close as she dropped her knees to the outside of his legs, pushing her hips and pubic mound harder against him. The scent of strawberries was very heavy and strong now, giving Kenny a pretty good idea of what she had in store for him.

“MMMMMMM!” Clarice moaned as she kissed Kenny, holding his face in her hands as she did. She softened her body to the point where she began molding it around him, his body sinking into it, something that slime girls did when they were very aroused. She could swallow him up and completely encase him if she wanted to, and while Kenny had wondered what that would feel like he was in no hurry to try it out for himself. After several very long and very enjoyable moments Clarice finally broke off the kiss, looking down at him with a smile on her face as she spoke.

“That was nice,” she said.

“Yes, it was,” he replied.

“Now let’s get down to business!” she said, her smile turning into a slightly wicked grin.

Without another word Clarice quickly hardened her body back to normal, then lifted herself up and spun around on top of him. She quickly dropped her big, thick, heavy thighs on either side of his head as she settled into the classic ‘69’ position, her massive breasts pressing against his lower abdomen. Her plump, smooth pussy with its open lips was right in front of his face, the aroma of strawberries stronger than ever. She grabbed his hard cock with her hand and pointed it upwards, then dropped her mouth down onto it, moving her hand out of the way so she could take it all in her mouth. She held her mouth down on his cock for a moment, gripping and squeezing his balls with one hand as she sucked on the hard shaft in her mouth.

“MMMMMMMM!” she moaned loudly, wiggling her ass in front of his face as she sucked on his cock. He got the hint, reaching up around her hips and grabbing her full, shapely ass in both hands and pulling her pussy down to his mouth. He began sliding his tongue up and down her slit and then in and out of her tunnel as she began sliding her mouth up and down on his cock, sucking harder and harder as she went. He knew that if she kept this up he’d be blowing the first of many loads into her mouth in no time, but he had a feeling that’s what she wanted, so he didn’t hold back – especially since the chemical oozing out of her body and being absorbed into his through his skin assured that he’d not only stay hard but cum several more times. His cock was rock-hard and throbbing right now, with Clarice’s mouth sliding up and down on it as she sucked hard, so he knew that when he did cum he was going to cum hard.

And it wasn’t long before he found out. It only took a few minutes of Clarice’s wet, sucking mouth sliding up and down on his hard cock and her hand gripping and tugging on his balls for him to cum. He felt his balls shifting and his cock widening, and when Clarice felt it she urged him on.

“MM-HMM! MM-HMM! MM-HMM!” she moaned around his cock in her mouth, nodding her head as she slid her mouth up and down on his shaft, sucking harder than ever.

That was all it took. Kenny groaned loudly as he came, his hips thrusting upwards as his cock exploded in Clarice’s wet, sucking mouth. He gripped her ass hard in his hands as his cock blasted stream after stream of hot, thick cum into her waiting mouth. She swallowed his cum as quickly as he could pump it out, and as her own orgasm quickly approached she closed her thighs tight around Kenny’s head, pushing her pussy down onto his mouth. She gripped his balls firmly and tugged on them as his cock continued shooting out streams of cum, and when he put his lips on her big clit and sucked she came hard.

“NNNNNGGGHHHHH!” she moaned loudly as she came, her meaty thighs clamping down tight on Kenny’s head. Her hips bucked and jumped on his face as the waves of pleasure sent ripples through her slime body, and she held her mouth down onto Kenny’s cock as the last bits of cum came shooting out while her own orgasm ran its course. Clarice unknowingly merged her thighs into one mass around Kenny’s head, trapping him while her orgasm went on. When it was all over they were both left gasping for breath, and Kenny had to tap Clarice on her hip to get her to separate her thighs and set him free.

“Oh, sorry!” she said, giggling as she took her mouth from his cock, holding it in her hand instead. “I get carried away sometimes and don’t realize I’m doing that!” she said as she separated her thighs, holding them apart so Kenny could move a little and take a few deep breaths, his face covered with the shiny fluids of her pussy.

“That’s okay, really,” Kenny said, his voice a little muffled from her thighs on either side of his head.

Without another word Clarice lifted herself up and quickly spun around, lying on top of him again with her breasts on his shoulders and pressed around his head. She reached down and slid her hand between them, grabbing his cock and pointing it at her pussy, then immediately took it all inside her in one smooth, easy motion.

“Now it’s time to get serious!” she said, grinning down at him as she propped herself up on her elbows, her mammoth blue tits all but swallowing his entire head between them. She put her knees on the bed on either side of him and began lifting her hips up and down, sliding her tight, wet, slippery pussy up and down on his throbbing cock. She rode him faster and harder, increasing the tempo and force of her hips gradually, never taking her eyes from his as she did.

“I’m going to drain you dry, Kenny,” she said, grinning as she spoke, resting her chin on her hands as she looked down at him, his face nearly covered by her mammoth blue breasts as she rode his hard cock. “I’m going to milk the semen out of you over and over again!” she said, the bed bouncing beneath them as she rode him hard and fast. The room was filled with the heady aroma of strawberries, the slippery, squishy sounds of her slime pussy sliding up and down on his cock easily heard. Kenny’s arms were trapped at his sides so all he could do was lay there while Clarice lay on top of him, pinning him to the bed and riding his cock, her eyes closed and a big smile on her face. She wrapped her arms around his neck and pulled his head deeper into the valley between her huge blue breasts, holding him tightly.

It wasn’t long before the inevitable happened. The more Clarice rode him the more aroused she became, and it wasn’t long before her mammoth breasts merged into one, covering Kenny’s mouth and nose in the process.

“MMMMPHH!” Kenny cried out from inside Clarice’s one big breast, his eyes wide. He slapped her on her waist as he cried out again, and it took a few moments for Clarice to realize something was happening and open her eyes.

“Oh, my gosh!” she said, a look of surprise on her face. She immediately separated her breasts and then pulled Kenny’s head up from between them. He took a whooping breath as his mouth came free, his chest heaving as he caught his breath.

“Oh, Kenny, I’m so sorry!” Clarice said, a look of regret on her face. She sat still on his cock as she spoke, not moving while she made sure he was okay. “I just get carried away sometimes, and I forget that humans can’t breathe inside me like a slime man can,” she explained.

“It’s okay, Clarice, really it is,” Kenny said, still gasping for breath. “Just be careful, okay?” he asked.

“Okay, Kenny, I will!” she replied, her face lighting up. Then she started riding his cock again, picking up where she left off, only this time making sure that his face wasn’t covered by her mammoth blue breasts. She rode him hard and fast, the bed bouncing beneath them, and it only took a minute or two before Kenny’s cock exploded inside her again.

“Yes, that’s it, give it to me, give it to me!” Clarice cried out in glee as she felt his cock pumping and throbbing inside her, filling her up with another big load of cum. After three or four spurts of his cock Clarice came as well, being careful not to let her huge blue breasts merge around his head again as she rode her orgasm out. When it was over they were both left gasping for breath.

“Oh, my God, that was good!” she said, pushing herself up with her hands on the bed, straightening her arms out to look down at him. Her breasts were so big that they were still rest on his chest as she looked down, squeezing his cock with her pussy. Then, without another word, she sat up and spun around to face his feet, keeping his cock trapped inside her as she did. Kenny lifted his head and looked down as Clarice sat on his cock facing his feet, the blurry image of his cock inside her and the wad of his cum in her stomach visible. She began riding his cock again, hard and fast, lifting her full, rounded ass up and down as she slid her pussy up and down on his cock, the bed bouncing beneath them again.

From out in the living room Cindy and Lilah looked at each other, both of them grinning when they heard the noise of the bed bouncing and squeaking.

“Mom is really going to town on Kenny!” Cindy said, grinning.

“She sure is! I hope Kenny can take it,” Lilah said, also grinning.

“Oh, he can, trust me on this!” Cindy said, her grin getting bigger.

Back in the bedroom Kenny grabbed the bedspread in his fists and hung on as Clarice rode him hard and fast. She gripped his cock tighter than ever with her pussy as she rode him, intent on milking the cum out of him. Watching her huge, rounded, blue ass bouncing and shaking as she dropped it down on him coupled with how tightly she was gripping and squeezing his cock with her pussy brought him to the brink of orgasm quickly. He groaned loudly as his cock exploded once again, pumping and throbbing as it shot stream after stream of hot cum inside her.

“Oh, my God, yes!” Clarice moaned, holding her head back and moaning loudly as she felt Kenny’s cock pumping and pulsing inside her. She sat down hard and held his cock inside her, rotating her hips as she squeezed his cock with her pussy to get every drop out of him. When Kenny’s cock finally stopped spurting inside her she spun around to face him again, the blob of his cum visible inside her as she dropped her knees onto the bed on either side of him and immediately began riding his cock.

“You okay, Kenny?” Clarice asked, grinning down at him as she rode his cock hard and fast, dropping her big hips down onto him, her huge blue breasts shaking and swaying as she moved.

“Yeah, I’m hanging in there,” Kenny replied, reaching up and taking her huge, heavy breasts in his hands and squeezing them hard.

“Good, because I’m just getting started!” she replied, grinning down at him with a slightly evil smile on her face.

A little more than four hours later Clarice walked into the living room, a satisfied grin on her face and a big glob of Kenny’s cum visible inside her stomach. She was still naked, her huge blue breasts swaying as she walked over to the couch, her eyes sparkling.

“So is he still alive?” Lilah asked, grinning up at her mother.

“Yes, he’s alive, he’s just taking a break!” Clarice said, her grin getting bigger as she sat down on the couch between her daughters.

“I’d better go check on him,” Cindy said, getting up from the couch. “He’s just now getting used to me, and to have the two of you going at him – especially you, Mom – might be more than he’s ready for,” she said, walking across the room.

“He’s doing just fine, trust me!” Clarice said, giggling. Cindy heard her mom and sister talking as she walked down the hallway to their bedroom, and when she went inside what she saw made her giggle.

Kenny was lying spread-eagled on the bed, his arms and legs splayed out, his hair tousled and his cock red from overuse. His chest was heaving as he tried catching his breath, and when he heard Cindy come into the room he turned his head and looked at her, a smile crossing his face.

“Hi, sweetheart,” he said in a soft voice, his tiredness showing.

“Hi, baby,” Cindy said, still giggling as she walked over to the bed and sat down, smiling down at him as he lay unmoving on the bed. The air in the room was heavy with the scent of strawberries, left over from Clarice’s arousal. She reached out and rubbed the top of one of his thighs as she spoke, her voice soft.

“I see you survived your first session with my mother,” she said, suppressing a giggle.

“Yep. Not sure how, but I did,” he said, nodding.

“Well, I did warn you about her, you know,” she replied.

“Yeah, but I had no idea she was going to be that intense!” Kenny replied, propping himself up on his elbows as he spoke. “I mean, I’ve never been fucked that hard or cum that many times in my entire life! I don’t think any human has!” he said, looking up at her.

“How many times did she make you cum?” Cindy asked, genuinely curious.

“Twenty,” he replied, “and all thanks to that chemical your body exudes when you’re aroused.”

“Yes, thank goodness for that!” Cindy said, giggling again. “But they don’t look like a couple of raisins,” she said, looking down at his balls.

“Huh?” Kenny said.

“Your testicles. Mom said that when she was finished with you they were going to look like a couple of raisins,” Cindy said.

“Not for lack of trying, that’s for sure,” Kenny said, smiling.

“You haven’t seen anything yet,” Cindy said, patting his thigh. “You forget that Lilah and Mom are going to be here for at least four more days, and eventually we’re all going to end up having sex with you at the same time, you know,” she said, grinning.

“Yeah, I know,” he replied, nodding as he smiled. “If the three of you don’t fuck me to death before then, that is!” he said, chuckling.

“Oh, I don’t think you have to worry about that,” Cindy said.

“Right now I’m going to go take a shower, then I’ll come out into the living room and join you,” he said.

“Okay, baby,” Cindy said, getting up from the bed and stepping back as he got off of the bed. “I would suggest you not bother getting dressed again because we’re just going to take your clothes off of you again anyway,” she said, smiling at him.

“Gotcha,” Kenny nodded as he got off of the bed and stood up, his knees weak.

“See you in a little bit, honey,” Cindy said, walking out of the room.

“This is gonna be a long night!” Kenny said to himself as he hobbled to the bathroom, a smile on his face.

Ten minutes later he was standing in the shower letting the hot water run over his sore body, the room filled with steam as he relaxed with his eyes closed, leaning back against the glass wall of the shower. He didn’t hear either the bathroom door or the shower door open, and the first indication that he wasn’t alone in the shower was when he felt two huge, heavy breasts pressing against the sides of his head and the tops of his shoulders. He opened his eyes and saw Lilah smiling down at him, her smile getting bigger as she pressed her body up against his, pushing her huge breasts against the shower wall behind him and mashing them together around his head. Then he felt her hand on his cock, her fingers wrapping around it and tugging on it as she spoke.
