As the early morning sun shone through a crack in his curtains Biff slowly awoke. He lay perfectly still for a while. His new role in the experiment forgotten about for now. He felt really well rested and extremely comfortable having this big bed all to himself.
His bedsheets were softer than he remembered and he could feel some silk material draped on him too. He got an itch on one of his legs and still half asleep he used his other foot to scratch it. His two legs rubbing off each other was the first sign of how much things had changed. Both legs were a smooth as a babies and the silk material moved around his waist as he turned. His underwear also felt much tighter than he had ever remembered and they were gently cradling his penis and testicles. The underwear felt like it was getting tighter and tighter but the reality was that he was getting an erection from all the erotic sensations he was feeling. He ran one of his hands down his chest, feeling the soft material of the nightie he was wearing. The bottom of it sat just below his waist and snaking his hand down further Biff took a hold of his penis, feeling it's girth, stretching the lace panties he was wearing and trying to peek itself out. Popping his hand inside the waistband of the panties Biff gave his penis a few strokes. Memories of the previous day were now coming back to him. He remembered the experiment he was now part of. He remembered that he was now playing the role of a single mother to 3 girls. He remembered getting dressed in these panties and the nightie. He remembered shaving off all his body hair yesterday and how soft and smooth he felt getting in to bed last night.
He was finding all of these new sensations incredibly arousing and he kept pumping on his penis as some soft moans and gasps escaped his lips. Even the sound of his moans was turning him on, sounding very womanly. His other hand had snaked its way back up to his chest and was rubbing his nipple through the soft material of his nightie. He had never taken any pleasure from his nipples in the past but now he was loving it. Combined with the feeling of his soft legs rubbing off each other and his continuous rubbing of his penis it didn't take long before he erupted in orgasm, shuddering and rolling around in the bed. Coming back to his senses he took his hand out of his panties. He had spilled some of his load on his nightie and the rest on his bed sheets.
He slowly got out of the bed, stripped off his nightwear and prance into his private bathroom to have a quick shower before the rest of the household woke up.
