Dylan is her boyfriend, and he joins the fun.

“Oh shit, not now,” moaned Heather. “Can you just tell him to go away?” Dylan was the quarterback and captain of the high school football team, and Heather’s on-again-off-again boyfriend.

“Tell him yourself,” said Billy.

“Fine,” Heather said angrily, grabbing her pajamas and starting to step into them.

“Nuh uh- no clothes. You go just the way you are. And no leaving the house.”

Heather gave her brother a frustrated look, before composing herself. “Can I at least clean my face?” she asked.

“I said just the way you are,” said Billy. Dylan knocked again at the door.

“Fine,” Heather said angrily, throwing her pajamas down and storming out the door. Heather approached the front door with trepidation, trying to figure out how to get out of this situation. Dylan knocked again.

“Who is it?” Heather called through the door.

“It’s me, Dylan,” he shouted back.

“What do you want Dylan?” Heather asked, still keeping the door closed.

“I was concerned when you didn’t show up for school, so I figured I’d swing by on my lunch break. Can you let me in?”

“I’m fine Dylan, and kind of busy- I’ll see you later.”

“C’mon Heather, just open the door. I don’t want to keep shouting.”

Heather sighed, and then opened the door just a crack. She hid her body behind the door, and moved so that just her eyes were visible through the crack. “What do you want, Dylan? I told you that I was alright.”

Dylan pushed gently on the door. “Come on babe, let me in. I was thinking that if you were alright, that we might, you know... have a little ‘afternoon delight’ before 5th period.” He pushed a little harder. Heather was pushing back, but the door slowly opened wider.

“Not today Dylan. I’ve got a lot on my mind, ok.”

He pushed again- the door was almost wide enough for him to slip inside. “If you don’t want to fuck, then how about just a quick blowjob?” He gave one last shove to the door, and stepped into the house.
Dylan stopped in his tracks, as he caught sight of his girlfriend buck naked in the front hallway. She reeked of sex, and he was instantly aroused.

“You dirty girl- have you been petting your kitty thinking about me?” Dylan grabbed Heather by the hips and pulled her against him. “Come give me some sugar.” He kissed her on the lips, while sliding a hand down her ass and between her legs.

Almost immediately he pushed her away, and wiped his face with the back of his hand. “What the fuck?” he said, examining his hand. “Is that- oh fuck it is!” Dylan spit on the floor, trying to cleanse his mouth of the taste of another man’s cum. “Are you fucking some other guy up there?” Dylan shouted, in a rage.

Heather instantly broke out into tears. “It’s not my fault! It’s my brother, Billy. You’ve got to believe me. I think he **** me into doing whatever he says!” Heather was sobbing.

Dylan looked at her incredulously. “What the hell are you talking about?” Heather described for him the events of that morning, and her belief that Billy must have **** her. When she was done, Dylan was furious.

“Where is that little pervert? I’m gonna kill him!” Heather pointed upstairs, and Dylan stormed off, telling her to wait there. Heather heard a door slam upstairs, followed by some shouting and what sounded like furniture being knocked over. Then there was silence, for what seemed like ages.

Finally, after five or ten minutes, Dylan came walking back downstairs.

“What happened?” Heather asked anxiously.

“Don’t worry- I took care of it,” replied Dylan, a big smile on his face.

Heather also smiled, and wrapped her arms around Dylan’s neck, giving him a big hug. “Thank you so much. You’re my hero!” She gave him a peck on the lips.

“How ‘bout I get my hero’s reward now?” asked Dylan, grabbing her ass.

Heather pulled his hand away. “Listen Dylan, it’s not that I’m not grateful- I am. I’ve just been through a lot today. Maybe tomorrow, huh?”

“Follow me upstairs to your room,” answered Dylan.

Heather started to protest, before looking down and realizing that she was actually following him without realizing it. She started to get a sinking feeling in her stomach.

They reached her room and Heather walked in, at once seeing Billy sitting naked on her bed.

“What the fuck Dylan- I thought you said you took care of it?” exclaimed Heather, spinning around to look at Dylan and noticing the large tent that was now in his pants.

“I did take care of it babe.” Dylan put his hands on Heather’s breasts. Billy and I had a nice conversation, and he explained to me that he could make you do whatever I told you to do. And hey, that’s just too good to pass up.”

Tears came to Heather’s eyes, and she looked over at her brother who had a wide grin on his face. Billy was happy for two reasons- he had fucked even more with his sister’s mind, and he also had a little plan in store for that douchebag Dylan as well. What Dylan didn’t realize was that Billy had messed with his mind too. Not only did he **** Dylan to accept this ‘deal,’ but he also made some permanent alterations to his mind. From now on, Dylan could only achieve or maintain an erection, or reach climax, in the physical presence of at least one other naked man. Billy thought that this ought to create some interesting situations in the locker room for Dylan, and would also leave him with the worst case of blue balls known to man. But Dylan wouldn’t find that out until later. Billy had also altered Dylan’s mind so that he couldn’t cum at all that day- Billy didn’t want Dylan to have the pleasure of cumming with Heather even if Billy was there.

“Why don’t you get on your knees and blow me,” Dylan instructed Heather. She dropped to her knees, unzipped Dylan’s pants and fished out his cock. It was smaller than Billy was expecting. Wrapping her lips around the head, Heather starting sucking.

Billy leaned back and watched as his sister blew the quarterback. At first, Dylan let Heather work his cock on her own, but as time passed Dylan got more and more aggressive. Eventually he had her by the back of her head, humping her face as Heather gasped for air. Dylan was desperately trying to cum in Heather’s mouth. Her eyes were filled with tears, and every now and then Heather caught Billy’s eyes with her own, silently pleading for him to stop her ****.

Billy got an idea. This was the perfect opportunity for him to try something he’d always wanted to try. He got up and tapped Dylan on the shoulder. “Hey Dylan, why don’t you fuck my sister’s sweet little pussy?”

Dylan looked exhausted and frustrated at his inability to cum, but he followed Billy’s instructions. Dylan positioned Heather on the bed, on her back, with her head near the end of the bed and her legs spread wide. He climbed between her legs and slipped inside her, the path made easier by Billy’s recent cum into that pussy.

Dylan’s thrusting pushed Heather forward on the bed, until her head hung down off the edge. Billy got up, walked over to Heather, and rested his dick on her lips. Without complaint, Heather sucked Billy deep into her mouth. For a few minutes he fucked her face, but when he was good and wet Billy pulled out.

He turned around and pointed his ass at Heather’s face. Looking over his shoulder he saw a momentary look of disgust on Heather’s face before he bent over, pushed his ass onto her face, and ordered her to “Lick my ass.”

Billy squirmed as he felt his sister’s tongue slide up and down his crack and around his asshole, like a wet, slippery snake. As he mentally guided her, she bathed his ass in saliva before poking her tongue into his tight hole. It tickled him little, and felt a little strange, having Heather’s tongue wiggling around in his ass.

At Billy’s direction, Heather reached one arm above her head and around Billy’s waist, and she started to stroke his cock while she licked his ass. He closed his eyes and enjoyed the feeling of a hand stroking his cock and a tongue in his ass.

After a while, Billy pulled his ass away from his sister’s face and stood up. He looked back and Dylan, who was feverishly pumping away at Heather’s pussy, desperately trying to cum. Dylan was panting and sweating, and looked more in pain than pleasure.

“Dylan, take a seat,” Billy said. Dylan climbed off of Heather and gingerly walked over to the chair in the corner. His cock and balls were swollen and sore, and it made walking difficult. He eased himself down into the chair.

Billy had Heather roll over and get onto her hands and knees, and lower her head to the bed. This had the effect of putting her ass on display for him. He ran his hands over her ass, feeling the smoothness of her skin and the tightness of her ass.

Billy gave Heather a swat on the ass. “Pull these cheeks apart for me,” he commanded. Heather reached back and with one hand on each cheek, spread her ass as wide as she could. Billy admired her crinkled little brown hole.

“Ever been fucked in the ass before, sis?” Billy asked.

Heather said “No,” and let out a little sob.

“Well you’re about to find out what it feels like.”

“Come on Billy, please, not there. Haven’t you done enough to me today? Fuck my pussy, or I can blow you, but don’t fuck my ass,” she pleaded.

Billy placed a finger on her asshole and applied light pressure. Slowly his finger started to sink into her ass. He wiggled the finger around, making her squirm.

Billy slipped a second finger into her ass. “Oh I’m gonna take your anal cherry, sis. The only question is, do you want me to make it so that you love having my dick up your ass?” He started thrusting his fingers in and out of her asshole. “Should I make you crave my big dick up your tight little shitter every moment of every day? Whether you’re at school, alone, with your friends, or sucking off douchebag over there,” he nodded toward Dylan, “all that you’ll really want is to come home, strip down, bend over and beg me to shove my cock into your bunghole.

“Or if you prefer, I can just let this hurt like a motherfucker. Your choice sis. What’s it gonna be?”
