Family Cabin

Chloe moved up to sit on Britt's face, Sam's position making it too awkward to continue making out with her. He watched as she ground her pussy into Britt's mouth, her little asshole tightening as she was licked. Licking his thumb, Sam reached forwards and placed it on her puckered hole, massaging it gently. Occasionally reapplying his spit, he managed to push his thumb into her up to the first knuckle.

She moved up, his thumb popping out of her ass, and returned to her initial position, body parallel to Britt's. Then she looked back at him, nodding.

Sam pulled himself from Britt, moving his cock to the other pussy before him, mixing Britt's juices with Chloe's as he pushed inside her. Chloe reached back and grabbed his hand, placing it once again at her ass. Taking the hint, he began to ease his thumb back into her.

Britt's hand reached up, cupping his balls, gently massaging them in her palm, fingers at his taint. The added stimulation sent a tingling sensation through his lower body, and he stilled halfway inside her, cock spasming as he shot into his sister, Britt continuing to massage the cum from his balls throughout.

He retreated as Chloe and Britt continued, his cum spilling onto Britt's stomach. They were about to leave, but had devolved into one final fuck after they'd finished cleaning up. Watching, he felt a pang of regret that they had to go. This week had opened up so many things to him, and he had no idea how long it would be before he saw his little sister again. He just hoped it was soon.
