Billy took his mouth from her tit, and the pain lingered from the chewing he had given her tender nipple. She felt him move, and she tried to turn her head, her hips still thrashing along with Tony's cock.

Billy slipped his pants off, then his shirt, and Lynn knew he was going to fuck her next. His cock stood out in thick hardness, the head almost purple in swollen smoothness. He was on his knees, looking at her body and jerking his fist back and forth on his cock. Lynn couldn't take her eyes off it, swallowing with a dry throat.

Billy pressed his cock into her hand, closing her fingers around it. Lynn surprised herself by clutching his cock tightly in her fist. Billy held her hand around his cock and tried to make her jack him off, but Lynn refused. She held his cock tight, but she wasn't going to jack him off.

He began to fuck her fist instead.

Feeling Billy's cock throb in her fist, Lynn moaned. Her hips began to move faster, fucking at Tony's cock. She couldn't help herself. She could feel every inch of Tony's cock plunging into her cunt, and to her horror, her cunt was responding by gripping his prick tightly, her ass bouncing in its limited movements.

Her eyes were glassy as she watched Billy fucking her fist. She tried time and again to fight the insane passion that was growing in her body. Yet, she held Billy's cock as hard as she could, feeling it slide in and out, and Tony's cock was increasing in speed. She knew they would come, and when they did, one cock would squirt into her fist, the other up her cunt.

With his cock pumping into her fist, Billy started to pinch and pull her nipples again. The sharp pain shot through Lynn's body, sending pleasure through her. She felt an orgasm swelling deep in her cunt, and she attempted to stop it, not wanting to give her stepson the satisfaction of making her come.
