Isabel is horrified, but can’t stop herself.

Letting out a long, gasping sigh Izzy let herself become lost in her pleasure. Pure bliss washed over her as each rope of fresh seed pulsed out of her. Spasms rocked down her body, making her hips buck against the warm mouths that were still working over her. For all the torment her mutation put her though, Izzy could at least be grateful that it also extended her orgasms well beyond human norms. More semen than several men could have produced in an entire day flooded out of her, and the woman sucking her eagerly drank down her essence. It seemed like that moment might last forever… then Isabel’s head cleared enough to remember just whose mouth was on her.

Looking down slowly Isabel felt her chest clench in horror as she got a good look at her mother’s lips wrapped around her cock. The woman who’d gave birth to her, raised her, was still eagerly sucking up and down her shaft. A few last spurts of come pulsed out of her, and she could see the muscles in Lillian’s throat move as she swallowed them. Once she saw her daughter was staring at her she even gave a playful wink.

There was also the fact that another girl, one she’d barely met, was still eagerly lapping at her pussy. For a girl who’d only just begun to accept that she might be bisexual, it was too much. Taking a few stumbling steps backwards she tried to escape the two women’s ministrations, but forgot that her mother still had a hand braced on her thigh. Loosing her footing Isabel went tumbling backwards, her back hitting the edge of the mantelpiece and sending the rack of fireplace tools clattering to the floor.

“Are you all right dear?” Emma was looking at her smugly from the couch, her fingers still pumping slowly in and out of her.

A last rope of semen had splashed over both Lillian and Jubilee’s faces as Izzy had fallen. The older woman simply ignored it, instead offering her daughter a concerned look. Jubilee was wiping her face clean with her fingers, sucking them clean with each pass.

“I… I just got a blowjob from my mother!”

“Yes. I do believe you asked for it. Begged in fact. Now be a good girl and thank her for it”

“…but…” The blonde gave her a cold look, somehow managing to look utterly intimidating despite the fact that she was playing with herself. “Thank you for the blowjob Mommy.” That got a broad, come covered smile from the woman in question.

“Of course Sweetie! I just wished you’d asked sooner.”

With that Lillian crawled forwards and captured her daughter’s mouth with her own. Izzy tried to pull away, but with her back to the wall there was nowhere to go. She tried to protest, but it was muffled against her mother’s lips. The warmth of Lillian’s tongue slid into her daughter’s mouth, playfully seeking out its counterpart. To her disgust Isabel could still taste her own seed. It occurred to her that she was more than strong enough to push her mother off of her, but thought never seemed to turn into action.
