Quickly making his way up stairs, Pete went in to the bathroom to get ready for bed. He hoped Biff hadn't noticed but from his reflection he could tell he looked kind of flushed with arousal. As he took off his dressing gown his state of arousal was even more obvious due to his erection bulging out of his panties and lifting the hem of his nightie slightly.
He tried to clear his mind and started to brush his teeth. With that done he decided to use the toilet before bed. Without even thinking about it he raised his nightie, lowered his panties and sat down on the toilet to do his business. Finishing up in there he made his way back to his bedroom, turned off the light and crawled under the covers.
Lying in the dark he started to process the feelings he was having during the movie. He was going over that scene at the end again and soon felt his erection growing, the tip of his penis making its way out of his panties and rubbing against the soft material of his nightie.
As a bit of an experiment he tried to think of some of the girls in school that he had crushed on in the past but the thoughts did nothing for him. He remembered Tiffany with her big boobs which she wasn't afraid to show off. Seeing those boobs in the past used to be the highlight of his day but given the current role he was forced into the though did nothing for him. They were just boobs after all, he thought, we've all got them.
His mind drifted back to the male lead in the movie they had just watched and he felt his heart flutter and his penis twitched in it's lace enclosure. He started to rub himself through the nightie and quickly found himself imagining himself getting hot and heavy with the famous heart throb. He felt his kust building rapidly and he soon erupted into his nightie. He was lucky that he didn't completely soak himself or his panties. Coming to his senses in the after glow he quickly and carefully removed the night and bundled it in to his laundry basket and quickly put on another one before getting back in to bed and drifting quickly off to sleep with a smile on his face.
