She runs away

Colleen could not very well refuse him now, although she could feel the guilt welling up as she started to think about what she had done. Finally she blurted out, “I can’t do this anymore.” and ran from the room grabbing her clothes.

As the door closed behind her Ben lay back on the bed, his cock even bigger now, swaying at full erection. He was frustrated and needed to cum some more. He gripped his cock with both hands, thrusting his hips, jamming his cock through his double fists. He was thinking about his Mom’s awesome tits, and tight pussy as he jacked off. He was so turned on by actually fucking his mother that he could not stop thinking about her big nipples, firm tits and tight pussy. He closed his eyes, visions of his naked mother sucking his cock filled his head.

Colleen crept back to his door, shame filling her as she cracked the door open and watched her son masturbate. Her fingers dropped to her soaked cunt, his slippery cum and her own lube creating a gooey mess. Her clit was huge and she rubbed it hard, bringing herself to orgasm quickly as she watched her son’s massive erection spurting even more cum, the long jets of jizz coating his chest. Colleen’s legs were weak to the point she almost collapsed as she watched Ben’s cock continue to swell, his hard thrusting never slowing down. He cock was bigger than anything she had ever seen, or felt. She had her share of boyfriends before she was married, but none of them sported a cock the size of her son’s. He had filled her tight pussy in ways she had not thought about in years.

Her pussy juice was dripping down her legs, as she used her long fingers to stuff her fuck hole. With one hand she jacked her clit, while the other hand’s fingers stuffed her cunt. Thrusting her fingers into herself in time to her son’s frenzied thrusts was hard but worth it as she climaxed again and again until she was too exhausted and clit to hypersensitive to go on. Ben jerked his cock hard and ejaculated what seemed like his biggest load yet, the long strings splattering all over him as he lay on the bed. Just when Colleen could take no more his cock finally started to shrink, and Ben lay back exhausted from his masturbation marathon.

Colleen went back to her own bed and collapsed into a deep slumber. It had been a very strange night.
