Chapter 4

It had been a few weeks since Tammy lost her virginity to her brother, Patrick, while his girlfriend, Katie, watched. Katie then proceeded to eat the cum out of the newly fucked girl. All three pledged to continue their dalliances together whenever it was possible, but they also knew they had to keep it secret. They couldn’t all hang out together whenever they wanted, otherwise Tammy and Patrick’s parents might grow suspicious to why they were suddenly getting along so well.

So, for the past few weeks, Tammy and Katie weren’t able to share Patrick together. Each of the girls took their opportunities when they presented themselves. Katie and Patrick would go out together on the weekends or find a place to hook up at school. Tammy and Patrick would try to find times when their parents were gone or asleep to mess around. What they were all waiting for was this upcoming weekend, when Katie would be fully on the pill and safe for Patrick to cum into. They had been using condoms when they were alone but forsook them when Tammy was involved. They knew the risks then, but since it wasn’t often, they took them.

Now just because Tammy and Katie couldn’t get together, didn’t mean they didn’t talk. The two girls had become close friends ever since Tammy was caught spying on Katie and her brother. They would call and text each other often and tell each other what they had done with Patrick when they were alone with him. They didn’t want to keep secrets from each other, it was challenging enough knowing they were sharing the same man.

The two girls also missed their own little playtime. While it was fun to fuck and suck Patrick’s cock, they both enjoyed the more feminine aspects of each other. Both girls loved to eat each other’s pussies and finger each other. It was different with a girl, softer, gentler, and they knew the best ways of getting each other off. The only time the two had been able to get together was to buy some clothes the week before at the mall. The two snuck into a changeroom and played a bit before they almost were caught by store staff.

It was three days before Katie’s parents were supposed to go out for the night and the siblings was going to go over. The three of them were all really excited, Katie and Tammy talked at length about getting to be together again, and Patrick just couldn’t wait to have another threesome with his two hot, willing girls.

Patrick had just come home from soccer practice when he noticed his parents weren’t home. He looked for Tammy in her room but didn’t see her, disappointed he stripped and jumped in the shower. What he didn’t know was that Tammy was home, hiding so she could surprise her brother in the shower. She had been hot and bothered all day, she tried playing with her pussy but nothing she tried filled the gap quite right, even a wayward banana. She needed the real thing, and it was only a doorway away.

She quietly took off all her clothes but a long T-shirt, just in case her parents came home early. She tiptoed over to the partially open bathroom door, hearing the shower running and her brother singing, and looked in. She could see through the opaque shower curtains that his cock was hard. Her pussy got wet just thinking about that thing sliding up into her again. She snuck in the door, careful not to make the hinges squeak and pulled off her shirt.

He seemed to be distracted by soaping his hair as she attempted to recreate the scene from Psycho, pulling the shower curtain open quickly while holding a toothbrush. Patrick jumped and nearly slipped backwards in the shower from fright, he stumbled back to his feet and looked angry.

“Tammy! What do you think you’re doing? You could have killed me,” he yelled.

Tammy was still laughing, not taking his anger seriously. She knew he was a little hot tempered but would calm down quickly.

“Think this is funny do you, wait till I get my hands on you,” Patrick said, grabbing her by the waist and lifting her up into the shower before closing the curtain again to keep the water off the floor.

“What are you going to do to me, big brother?” she asked, looking at him in her innocent little girl face.

“Whatever I want, little sister. You owe me for taking a few years off my life and I’m going to take payment in kind.”

Tammy loved this big-brother, little sister game. It turned her on to be reminded that she was fucking her brother, and she loved letting him use her for his own sexual pleasure. Tammy loved being told what to do, she realized that her first-time watching Katie and Patrick.

“Please, don’t hurt me. I’ll do whatever you want,” she said in her playful voice.

“Suck on it then!” he said, puffing out his chest while pushing her down on her knees in front of him. Tammy got into position, her face at eye level with his engorged cock. Patrick took her head and guided her mouth onto his cock, Tammy just opened her mouth wide and took it all in. Tammy had been getting lots of practice on Patrick’s cock of late.

Last week, she was unavailable for sex, so she took that opportunity to have Patrick in her mouth as much as possible. While sex was better for both of them, blowjobs were faster and easier to sneak around and do. There wasn’t as much noise, she could keep her clothes on, and Tammy made sure there was no mess by swallowing. Tammy would have sucked off Patrick about three times a day, if she could, unless he had a date with Katie. Then they only did it when he got back, in fairness to Katie.

Tammy went to work on her brother’s cock, she used her hand to stroke the bottom part of his shaft while she took the rest into her mouth, bobbing away. Patrick groaned, holding his sister’s head as she sucked on him. The water of the shower splashed down on them, water ran over Tammy’s face, but she continued her oral assault on Patrick. At points, she would open her throat and take his entire 7-inch cock into her mouth, letting it hit the back of her throat, before pulling off, taking a breath, and doing it again. Patrick loved it when she did that.

“I’m getting close Tammy,” Patrick grunted out.

Tammy pulled him out of her mouth briefly, “where do you want to put it?”

“Down your throat,” he replied.

Tammy took him right back into her mouth and worked on the head of his cock with her tongue. She twirled it from the underside, up and over the head a few times, driving him wild. She could feel his body tensing up, getting ready for release, she was waiting for the sign, and it came quickly after that, just like Patrick. He tapped her head and grunted. Tammy was quick and shoved him back down deep into her throat where he unleashed a torrent of cum straight down it, into her stomach. Patrick held still as he felt her throat muscles massage the remaining cum out of him before he was done and pulled out of her.

“God, Tammy. You are incredible at that. I almost think you are better than Katie now, but don’t tell her that.”

“I won’t, she’d kill both of us,” Tammy laughed, “besides, I learned everything from her, I would still just be an innocent virgin sitting in my room if it wasn’t for her.”

“Yup, and I wouldn’t be thinking of fucking you from behind at this very minute, if it wasn’t for her.”

“Oooooo, you have another one in you?” Tammy asked, looking down at his still hard cock.

“Yup, you want it in you, little sister? You want your brother to fuck your tight little pussy?”

“Oh yes, I’ve wanted this all day. Take me from behind, big brother.” Tammy spun around and faced the back of the shower wall. Patrick bent her over, looking at her small ass and tight, pink pussy. He ran his cock up and down her slit before shoving it deep in her wet box, bottoming out in her.

Tammy just groaned as she felt the thing she’d wanted all day stretch her out in wonderful, pleasurable ways. Patrick felt himself surrounded by the tight, slick walls of his sister’s vagina. He loved the feeling knowing he was doing something that was so wrong, but that made it feel so right. He pulled out most of the way and plunged back in, shoving her slightly against the wall. Tammy just groaned at the thrust, encouraging him to keep it up.

Patrick started fucking her at a steady rhythm, pulling almost all the way out before slamming back into her. Tammy was loving it; her body was already tingling from the sensations after only a few minutes. It didn’t take long for her to have her first orgasm, crying out and tightening her muscles around his cock. Patrick slowed down for a moment, so that he wouldn’t finish too fast before resuming his pace. His hand reached down and played with her small tits as they dangled there underneath her.

Tammy, for her part and pleasure, slipped one of her hands down and started playing with her clit as he was fucked from behind, increasing her own pleasure. Tammy’s body was rocking slightly as she neared another orgasm. For a split second, she moved slightly more forward than usual as Patrick had pulled out and was about to slam back in. In that brief moment, his cock slipped out of her and his thrust forward, entered into her tight virgin ass instead.

Patrick stopped just as his balls reached her skin and Tammy cried out at the intruder that had forced its’ way into her backdoor. They both froze still, unsure of what to do.

“Don’t move, Patrick. Please, it hurts. Just don’t move.” Tammy begged.

“I won’t, are you ok? That was an accident.” Patrick was worried, he never wanted to hurt his sister in any way.

“I know, Pat. It hurts, just stay still. Moving causes it to hurt more, just stay inside me for now.”

Patrick tried to stay perfectly still, barely moving a muscle, but his cock had a mind of its own. Inside his tight sister’s asshole, he felt like his dick was getting squeezed by vice grip. It felt amazing, he’d never been in a girl’s ass before. He had asked Katie before, but she was lukewarm on the idea, she had a hole specifically for that already and that hole felt good. She didn’t want to risk the pain of something like that. Patrick’s cock involuntarily twitched inside Tammy’s ass.

“Patrick, what are you doing?” Tammy said, “Don’t move, it’s just starting to relax and feel better.”

“Sorry Tammy, it’s just twitching on its own.” Patrick tried to think of something else, but he couldn’t, his cock moved again.

“Pat, please I...” Tammy trailed off as his cock moved once again, “Oh!”

“Tammy?” Patrick sounded confused.

“That time, something felt good. Like it hit a good spot in me.”

“Should I try to pull it out now?”

“Yes, give it a try but go slowly.”

Patrick backed his hips up slowly, taking an inch out of her bowels at a time. Tammy didn’t say anything but had a strange look on her face. Pat stopped to see if there was a problem.

“Why’d you stop?” Tammy asked.

“You had a strange look, I thought I might be hurting you.”

“No, it just felt really strange. Sore, but it also started to feel good. Keep going, I’ll tell you to stop if I need it.”

Patrick resumed slowly pulling his cock out of his sister, he was almost all the way out when Tammy pushed back, stuffing the thing back into her, letting out a loud groan.

“What the hell, Tammy? It was almost out.” Patrick said slightly annoyed.

“I know, but now that the pain is almost gone, it’s starting to feel good. Why don’t you do a couple of thrusts into me, just to see. This could be your only chance to do this.” Tammy suggested, he thought about it and knew she was right. Plus, it felt really good for him already.

Patrick did a few thrusts into Tammy’s tight ass, it was incredible. It was very different than fucking a vagina, the tightness was right on her anal ring, milking his cock. Her ass also felt very hot inside. As he started fucking her ass, Tammy started moaning, encouraging him to continue. Her hands ran up to massage her own small breasts, playing with her nipples and squeezing her own breasts. Her hand then went down to her vacant pussy and started fingering herself while she was fucked in the ass.

“Oh GOD, Pat. I think I’m gonna cum!” she cried out.

Patrick just kept pumping into her back door, the pressure in his balls building as well. When Tammy cried out, her sphincter clamped down on his cock, nearly crushing it. Patrick cried out as well, the sensation caused him to cum into Tammy’s ass, filling her bowels with his hot, sticky seed. Both siblings nearly collapsed after they had finished their orgasms. Patrick could see Tammy’s asshole was still gaping open and sperm was leaking out. They cleaned off in the shower, Tammy’s ass being slightly sore and sensitive, was helped out of the shower after and they dried off. They kissed each other for an interesting experience and got dressed. They both had a story to tell Katie later.

The weekend had finally arrived, and Tammy was excited to see Katie again. Katie’s parents were out of town on business so they would be going over to her place to mess around. As the evening approached, Tammy showered and put on a cute dress and Patrick put on some shorts and a polo shirt. They told their parents they were going to meet Katie and see a movie. The real plan was to head right over to Katie’s for an evening of sexual escapades.

They said their goodbyes and took the car over to Katie’s where she was waiting for them. She too was excited for tonight’s events. She couldn’t wait enjoy Tammy’s sweet pussy again and have Tammy pay-off her promise to eat her first creampie. They entered the house and as soon as the door was closed, Katie leapt up and hugged both of them, then planted a big, wet kiss on Tammy’s mouth.

“Well, nice to see you too Katie,” said Patrick, jokingly upset his sister got a warmer welcome than he did.

“You know I love you too, I just haven’t been able to really get my hands on Tammy in a while.” Katie replied, her hands sliding over Tammy’s small chest.

“I missed you too Katie,” Tammy said, leaning in and sticking her own tongue into the older girl’s mouth.

“Ladies, ladies please ... Let’s take this upstairs.” Patrick said with a grin.

Patrick put out his arms and each girl took one. Patrick walked up the stairs flanked by his lady lovers, his girlfriend and his own sister. As he reached the doorway to Katie’s room, he stopped, allowing the girls to go first and then followed them in.

“So, who do you want first Patrick?” Tammy asked, her eyebrow raised.

“Yeah Patrick, which one of us do you want first?” Katie added.

“Girls, I couldn’t choose between you so I’m going to choose both of you at the same time.”

“Coward” both girls yelled out before turning their attention to each other.

Patrick walked over to Katie and kissed her deeply, his hands roaming over her ass in her tight little pajama pants before turning to Tammy and kissing her. While the siblings made out, Katie moved behind Tammy and started undoing her dress, pulling down the zipper in the back. As it was lowered, Katie could see Tammy wasn’t wearing a bra. The dress now loose enough to be removed, Katie pulled it off the young girl’s shoulders, having it drop to the ground.

“You little slut,” Katie gasped. Tammy hadn’t put on any panties.

Pulling away from Patrick, Tammy said, “I didn’t want anything to get in the way.”

“Very nice.” Katie said, as the two girls exchanged saliva. Tammy slid her hands down under the thin shirt Katie was wearing, feeling her larger breasts. Tammy then put her hands under the hem of the shirt and pulled it over Katie’s head, exposing her breasts to the siblings. Tammy’s mouth latched onto one of Katie’s nipples, sucking on her tender flesh, while her newly freed hands roamed down into her older girl’s pants.

While Patrick watched the two girls play with each other, he stripped off his clothes and moved behind Tammy, running his hands over her small form. He brought his hands around to massage her small breasts, enjoying the feeling of her tiny hard nipples. He pressed himself up against Tammy’s ass and humped against her ass cheeks.

Meanwhile Tammy had pulled down Katie’s pants and had her hand firmly inside Katie’s wet pussy, fingering her and driving her mad. Katie’s fingers were now also inside of Tammy, rubbing up and down her slit. Both girls were soaked and primed for sex.
