No, the lust is too strong.

The burning need in his loins was too much for Adam. Instead of removing his hand from his squelching pussy, he began slowly rubbing himself through his drenched pajama bottoms. Pleasure radiated out from his snatch, suffusing his entire being. Adam' nipples hardened, rubbing against his pajamas, adding to the bliss he was feeling. Still staring through the keyhole and using his other hand to stabilize himself, Adam's eyes were transfixed by the display his mother was putting on.

"So... good... ah! It's throbbing sooo much," Monica moaned with abandon, her hand rapidly pumping back and forth between her legs. The other hand was busy massaging her ample tits and pinch or twist her nipples. The display drove Adam to the brink of insanity. His attraction to women was still intact, so the relentless moaning obviously had an effect in him, but his cunt needed to be, begged to be filled - and his mother's cock looked to be the perfect fit.

A part of his mind was horrified at himself, but he couldn't help wondering how it would feel to be penetrated by the thick rod, his lower lips spread open and his deepest parts stroked by the purple helmet. His hand slipped into his pants and he started to slide his palm over his labia, no pesky fabric in the way now. The feelings of lust intensified, causing his breath to become more labored.

In the shower, Monica had closed her eyes in bliss, her hand a blur on her dick. Adam could not deal with the sight before him any longer and slipped the first finger into his pussy... and a loud gasp left his mouth. Instantly, all his movements halted. Eyes wide open, he didn't dare breathe, but it was too late. His mother's eyes weren't closed anymore and she had stopped stroking her throbbing dick. By the way its veins stood out, Adam knew she had to be close to cumming, and the thought of her sticky spunk made his mouth water despite himself.

But he didn't have much time to marvel at his mother's magnificent rod - Monica had left the shower and moved towards the door. Adam wanted to get up, but his knees felt too weak and he was unable to move away. His mother opened the door and Adam found himself eye-level with her throbbing member. He realized that he was unable to take his eyes off of it. It was magnificent, thick, veiny and throbbed and lurched with his mom's heart-beat. His lips parted slightly and he leant forward towards it...

"Oh sweetie, no! I'm so sorry, I should have realized!" Monica cried, "I shouldn't have... but it felt sooo good..."

Adam's eyes were still transfixed by his mom's turgid prick, hand still buried in his pants. His mother's eyes went wide as she realized what he was doing and she knelt down, taking his wrists in his hands, pulling Adam's hands between them. His eyes followed her cock-head as if hypnotized. The smell of Adam's pussy juices hit Monica like a freight train, but she fought hard to suppress her desire to stuff her son full of cock, even if there was nothing she wanted more at that moment.

"You can't, sweetie! You'll change more! Maybe we can still reverse this, but you have to hold on, keep from masturbating."
