“You’re so big. Do I feel as tight as I think?”
“You’re perfect,” Bobby replied as he placed his hands on his sister’s hips.
Sarah swirled her hips, pulling up as she came full circle, pushing down as she started around again. She slowly increased her rhythm as she grew comfortable being on top. Bobby sat up, propping himself against his pillow, as he slid his hands to her front. One hand made its way to her breasts while the other gripped her stomach. He pinched her nipple as he lowered his other hand, his fingers slipping through her pubic hair before finding her clit. He could feel his cock sliding in and out of her just below. Sarah let out a moan as her brother’s fingers hit the right spots.
She felt good riding him, but Bobby wanted more control. He rolled to the side, his sister flopping to the bed on her stomach. He positioned himself behind her, grabbing her hips and pulling them up, her face still against the sheets. He slid in easily, pulling her hips back to meet each thrust. Sarah slid her hand between her legs, rubbing her clit, keeping tempo with her brother, inching her closer to orgasm. Her brother’s cock pushed deep, filling her inexperienced pussy, stretching it with each plunge.
“Fuck yes, you are so big. Fill me up, Bobby,” Sarah panted. “Make me cum, fill me with your seed, brother.”
Hearing her tell him to cum inside her pushed him perilously close. He wanted to oblige her, but not just yet. He didn’t want to do it from behind, as he wanted to be looking into her beautiful eyes when he climaxed.
“Flip over,” Bobby instructed as he was already spinning her by the hips. “I want to see your face when you cum.”
“Then fuck me harder, Bobby.”
He did just that, placing his hand on her legs, pushing them back, as he pounded into her, his hips smacking into her, his balls slapping against her ass. Sarah let out small grunts with each impact, her small breasts bouncing, her back pushing into the mattress. She reached down, mashing her clit, trying to finish what her brother had so expertly started. She wanted to let him make her cum, but she knew she needed the extra stimulation. Despite not being experienced with sex, she’d used enough dildos to know that penetration wasn’t enough, even with a cock as impressive as Bobby’s.
“Keep going, don’t stop, don’t slow down. I’m going to cum!” Sarah cried out.
“I’m cumming too,” Bobby responded, his face giving away his efforts to hold off his impending orgasm.
Bobby felt his sister clamp down around his member, pushing him over the edge. Her back arched at the same time that he unleashed the first stream of cum into her. Their orgasms were powerful, built up from the excitement of the day, far outpacing what they’d experienced in the morning. Bobby kept pumping as his sister writhed below him, his cum leaking out of her pussy, dripping down her ass crack, as he continued to pump into her. His orgasm was finished, but he wanted to make sure she got every last ounce of pleasure out of hers.
“Oh my god, oh my god, oh my god!” Sarah screamed, “Yes, yes, yes!”
Her nails dug into her brother’s back, scratching away from his spine. As her orgasm subsided, she pulled him tight, his body pressing down on hers as they kissed, their tongues intertwining as her body jerked a few more times. The kiss was intimate, almost more than the sex, sealing that they were more than just experimenting siblings. They were invested in each other as lovers now. They would still need to talk things over, but it was clear they both wanted to keep doing what the world said they shouldn’t. They’d have to keep it from their parents, they wouldn’t understand, but the siblings have plenty of time when their parents were at work.
“I love you, Bobby.”
“I love you, Sarah,” Bobby said, rolling off his sister.
Sarah snuggled her head into Bobby’s shoulder, his cum running from her satisfied cunt. She knew she should go on birth control if they were to continue fucking bareback, but there was something extra exciting about knowing there was a possibility, albeit small for her time of the month, of getting pregnant.
The four other girls stood huddled in the bedroom doorway. They’d made each other cum downstairs but had been drawn to the sounds of the fucking siblings, finding the door left open. If they hadn’t wanted an audience, then they should’ve closed the door, the girls reasoned. They’d been dying to watch the two lovers fuck, and seeing as though the siblings were consumed by each other it didn’t seem to be an issue. There was no reason to announce their presence, the girls choosing to silently watch from the hallway.
Now that the couple was finished, the girls silently debated whether or not to join them in the queen-sized bed. Candice licked her lips as she stared at the cum running from Sarah’s cunt, while Ashley fantasized about cleaning off Bobby’s cock, with hopes of bringing it back to life. On the other hand, the two siblings looked calm and peaceful in each other’s arms, oblivious to being watched. It seemed rude to interrupt them. There would be plenty of time for group play in the weeks to come.
In the end, the girls snuck away undetected, leaving Sarah and Bobby to fall asleep in each other’s arms. They went home to reconnect with their families and tell lies about what happened at the sleepover. That night, each of them thought of Bobby and each other as they slipped a hand between their legs, getting themselves off one last time before they fell into a deep slumber.
Dee drove past three pharmacies on her way home, opting to not stop at any of them. She wasn’t sure what she wanted to do. She was due to ovulate the next morning, meaning there was decent chance of getting pregnant, but something inside her told her to wait. She wasn’t sure if she wanted a baby, at least not yet, but maybe it was meant to be. She thought that maybe she should let fate be her guide. After all, it would be amazing to be forever tied to Sarah and Bobby. She could be his baby momma and keep the secret of him and his sister safe. It was at least worth taking a day or two to think it over.
