“Nnnngh, mhmm mmm,” Beck mewled into the mattress. I was worried about her for a moment before her head turned as she lay there under me. When I saw her face and the smile plastered across it, I knew my concern was unfounded.
“You got that right!” Jeremy grinned.
“Ohmigod,” Mandy exclaimed. “Is it always like this?”
I snorted a laugh at her question before I realized I was still lying fully atop Beck. I went to roll off of her, but she whimpered, and her hands somehow reached back and grabbed onto my legs, holding me in place.
Jeremy looked over at my curled-up girlfriend, smirking, “No, it absolutely is not!”
“Really?” Mandy asked, lifting her head up and looking around until she found Jeremy standing on the edge of the mattress.
“I’m serious,” He answered. “Stuff like this happens on occasion, but it’s not every time. It really just depends on who you’re with, right, honey?”
“Mhmm, yesss,” Beck sighed contentedly, nodding her head quickly, her grip tightening on my legs.
It was strange just to be lying on top of the older woman. It felt like I had to be squishing her. Sure, Mandy loved to feel my weight on her when I was on top, but the moment we both came, she usually pushed me off of her. Beck was the exact opposite. It was as if I were her heavy, weighted blanket or something.
“If it were like tonight every time, I don’t think I could handle it,” Mandy said.
“Too much of a good thing?” Jeremy asked.
“Holy shit, ya!” Everyone started chuckling at that, even Beck from under me, which was interesting. “My pussy is throbbing.”
“We should do this again,” Jeremy said, getting to his feet and looking far more stable. I looked over at Mandy to gauge her reaction before I replied to his suggestion. Mandy was grinning, and I was pretty sure she was blushing, but as flushed as she was from her orgasms, it was tough to tell which was making her face glow warmly like that.
“We should exchange numbers,” I suggested.
“Yeah, let’s do that.” Jeremy nodded. “Honey, where’s your phone?”
“It’s in the car...”
“Why’s it out there?”
“Pockets, my dress doesn’t have pockets.”
“I know that, but what about that little purse thing you insisted I buy you that went with your dress?”
“It doesn’t fit.”
“Seriously?” Jeremy looked aghast. “What’s the point of having one of those if nothing fits in it?”
“Because it’s cute!” Beck replied, as if it were the most obvious answer ever, and he should have known that.
Jeremy looked at me for help, but I could only shrug. It’s not like I have any idea why girls do what they do.
“Let me grab mine,” I pushed up with my arms, but Beck refused to let go.
“Honey, let him go so he can put our numbers in his phone.”
“I don’t want to move yet.”
I lowered myself back down, and she sighed happily, but when my face was low enough, I brushed my lips across her ear.
“Do you want Daddy to take care of you again?” I whispered, my breath low, airy, and barely loud enough for her to hear.
“Mhmm,” Beck moaned.
“Then be a good girl and let me up so you can give Daddy your number.”
“Mmm, okay.”
I gave her a little kiss on the top of her head, and she sighed, but released her hands from my legs so I could get up.
Once Beck let me free, it was only a quick couple of steps to my suit pants and a moment more to dig my phone from the pocket. Jeremy asked for my number and sent me a text that read, ‘Jeremy.’ Simple, easy. I added him to my favorites right then and there.
“Give me your phone,” Beck called out from the bed where she was still lying down on her stomach but was propped up on her elbows as she watched me and her husband.
“Huh?” I replied, confused. Jeremy had just given me their number.
“Bring me your phone,” Beck insisted. “I want to give you my number too.”
“Oh!” I blinked; apparently I was a little slow on the uptake, and that got both Beck and Mandy giggling. “Seriously, quit laughing at me. It’s not like I’ve done this...” I pointed around the room, “ ... before.”
Jeremy grumbled something off to the side, which I took as agreement and commiseration. If it wasn’t, I was really going to feel like an idiot.
“I’m sorry,” Beck did her best to swallow her laughter by holding her hand over her mouth, but that did nothing to hide the smile that remained around her eyes. “I guess getting a girl’s number, right in front of her husband, is probably a bit strange.”
“You think!” I agreed, my voice rising. That got Jeremy chuckling, and I spun and glared at him.
“Sorry, it was funny.”
“Come on, babe,” Mandy cut in, her voice high and light. “Just give her your phone. Do you want my number, too, Jeremy?”
“I’m always willing to get the number of a beautiful, younger—” The scowl that suddenly appeared on Beck’s face when Jeremy mentioned the term young gave him pause. “I meant, another beautiful young woman, like my wife.”
“Better...” Beck eyed her husband as he walked over to Mandy’s side to put her contact information into his phone.
“Here you go,” I said, offering Beck my phone, and taking her attention off of her husband, shifting it back onto me.
“Thanks, Daddy.” The look on Beck’s face made me blush as I took my phone back. I looked down at the thing and saw what she’d named herself in my contacts, and I just about choked... your daughter.
“What is it, what’d she do?” Mandy asked, instantly curious and almost sounding worried. I showed her my phone screen, and her eyes went wide, her hands covering her mouth in surprise as she looked at the grinning form of Beck. “You didn’t!”
Jeremy started laughing, a full-on belly laugh, when he saw what his wife had done. I could feel the heat rising by at least ten degrees in my cheeks. “Judging solely off of what happened tonight, you might get more than you bargained for on that one, honey.”
“I sure as shit hope so!” Beck fired back, her own cheeks pinking furiously as a massive grin spread across her face.
After our contact information had been exchanged, we all agreed, thankfully, that it was time to call it a night. There was no way I was going to be able to perform again. Through a lot of trial and error, I had come to terms with the fact that I was no longer the guy in high school with unlimited reloads. Not that Mandy hadn’t tried over the last year to prove that theory wrong. She had thoroughly. I was good for three orgasms; that was it, that was the limit. It would take something awfully crazy or special to get me going one last time and then achieve any kind of release.
“You’re going to call or text me, right?” Beck asked, standing next to Jeremy, her head resting on his shoulder as his arm wrapped around her waist.
“Sure,” I smiled, and she giggled happily.
“Well, it’s time we get going before Beck here finds another victim,” Jeremy announced.
“Hey!” Beck turned and smacked her husband playfully, but there was some heat behind it. “I don’t have victims.”
“Whatever you say,” Jeremy rolled his eyes.
“They’re all willing participants; there’s a difference.”
“Come on, babe,’ I grabbed Mandy’s hand and made to leave.
“What, wait!’ Beck cried out, with sudden panic, and hurt in her eyes. “No goodbye?”
I froze, not sure how I was supposed to proceed. The wheels were racing in my head for a solution. Normally, any decent guy would stay and not run out after sex. Was I supposed to kiss her? Give her a hug? Shake her hand? I immediately dismissed the handshake, which was just plain stupid.
Beck, thankfully, came to my rescue and slipped in, wrapping her arms around me and holding herself tightly against my chest before tilting up her head and giving me the sweetest, most innocent kiss on the cheek possible.
“Thank you for tonight.” Beck smiled.
“No, thank you,” I replied, giving her a quick kiss on her forehead, and I felt her body shiver against me.
“Come on, honey,” Jeremy groaned, after giving my girlfriend a passionate hug and kiss before grabbing his wife’s arm and pulling her away from me. “Sorry about that. I’ve never seen her get so attached to someone new like this.”
“Don’t worry about it,” Mandy snickered. “Tom loves it, even if he won’t admit it. Goodnight!”
“We’ll see you at the next party, right?”
“If we’re invited,” I replied, shrugging.
“Oh, you’re invited!” Beck called out as her husband dragged her away from the room and out of sight. “And you better show up!”
“Mmm, she really likes you,” Mandy said, pressing herself against me, taking the same position Beck had been forced to vacate moments before.
“Yeah, that was fun.”
When we left the house, I half expected we would run into my sister on the way out. Thankfully, that didn’t happen. The last thing I needed after such an amazing night was to see her in a compromising situation and have that mental image seared into my brain for who knows how long.
We were quiet as we walked to the truck. Mandy held my arm in hers and pulled it against her front. The night was getting a bit chilly, and with how skimpy her little dress was, I was surprised that she wanted to be as close to me as possible, using my body heat to keep her warm.
“I think I’m going to be sore tomorrow,” Mandy said, as she climbed into the truck and shifted uncomfortably in the passenger seat.
“That good?” I asked, getting into the driver’s seat, giving her a teasing grin. I knew it was good for her. From the way she orgasmed, it was obvious.
“He was pretty good,” She blushed, and I started chuckling. “But he wasn’t better than you, not even close.” I rolled my eyes at her, and she pursed her lips in response. “I’m serious. Jeremy was nice, and he knows how to use his dick, but he wasn’t able to hit my special spots like you can.”
“Thanks,” I replied, leaned over, and made kissing noises while keeping my eyes on the road. Mandy giggled and kissed me on the cheek.
“I love you, Tom.”
“I love you, too.”
It was quiet for a minute or so. Both of us seemed content and just happy to be in each other’s presence.
“I still can’t believe Beck was so...”
“So ... what?”
“You know, calling you Daddy like that!” Mandy giggled. “Then what she put in your phone, I mean, wow!”
There was no faking the shock and surprise in her voice as she mentioned Beck naming herself ‘my daughter’ in my contacts. I would have to keep that from wandering eyes. I didn’t need people asking me questions that I wouldn’t be able to answer.
“Yeah, that was unexpected.”
“It was crazy, Tom!” Mandy’s voice was high and excited. “It was kind of hot though, right?”
“Because she named herself my daughter in my phone?”
“Yes, but not just that. It was also how Beck was calling you Daddy, and the way she was willing and wanting to do whatever you said.”
“She wouldn’t have done anything I said.” I deadpanned. “You’re making it more than it was.”
“Oh, yes, she would have!” Mand nodded enthusiastically. “You didn’t see the look on her face when you told her to get on her knees, and she didn’t even blink an eye before she swallowed your cock like it was her job!” I barked a laugh; I couldn’t help it. I remembered that bit vividly. “It was SOOO freaking hot, babe!”
“You really like her calling me Daddy, don’t you?”
“Yeah ... It’s so naughty.”
“It’s pretty damned kinky.”
“You think she was thinking about her Dad when she was calling you Daddy?”
I was stunned that Mandy even thought it was a possibility. It wasn’t even remotely on my mind while we were with her and Jeremy. My girlfriend was pretty wild when you let her imagination go without keeping her in check, but that was too much.
“There’s no way in hell,” I answered. I shook my head as if what I’d just heard was flat-out crazy nonsense.
“Yeah, you’re probably right,” Mandy agreed, if reluctantly. “I’ll ask her about it later.”
