The alarm clock buzzed waking Biff up. He reached blindly out for the clock knocking a few things on the table before he found it. Groaning he sat up and rubbed the sleep out of his eyes. Yawning he got out of bed and headed to the bathroom. Along the way he idly scratched his butt. That was when he noticed it. His boxers felt different. Looking down he yelled "What the hell!?" He was wearing a pink thong instead of his normal boxers. More to the point he recognised the thong. It was Sarah's, his girlfriend, and it was the pair that he had brought her last week to spice things up in the bedroom.
Biff quickly took them off, wondering how they had got on in the first place. Biff then continued into the bathroom to relieve his bladder and then went to look in his drawers for some boxers. He gasped. Instead of his boxers, the drawer was full of panties and thongs each belonging to Sarah. "What are Sarah's panties doing in my drawer?" Biff wondered. There was no way he was going to wear them to school. His friends would laugh at him if they found out. Biff figured that he'd just go commando today and then try and find his boxers or buy some new ones after school. Taking a shower, he threw on some jeans and a red tank top and headed down for breakfast. His dad had already gone out to work and his mom was probably still in bed. So Biff just made himself some toast and then left for school wondering what had happened to his underwear.
