Sarah led them up to her room, hearts pumping as they anticipated her mom seeing them at any second. "Stay in here, Biff. I'll go see where she is." Before he could protest, she ran out of the room, spotting her mom in the kitchen halfway through dinner. Good. She won't see us. With that, she went back upstairs. "She's making dinner. Come on, we have plenty of time to pick out clothes for you. Later on if you don't change back we can go to the mall and get some clothes for you." She pulled a reluctant Biff into the adjacent room, closing the door behind them.
"What the hell, Sarah? I don't wanna wear your mom's clothes!" Biff protested, resolutely ignoring how badly his clothing fit, and how odd his voice sounded, and how different he felt in general.
"Well, would you rather go naked?" He looked down at himself with a glint in his eyes. "No, Biff! Eugh. You look like my mom. I don't wanna see her naked." Sarah sighed, shuddering in disgust. She ignored his protests, looking through her mom's drawers and closet for something he wouldn't bitch too much about. There wasn't much; her mom always liked to look her best, and was often entertaining guests. Even her casual clothes rarely included pants, and there wasn't a pair of shorts in the bunch. "You're gonna have to wear a skirt, Biff."
"What?! Are you serious? Your mom doesn't have exercise clothes or sleep pants or anything?" He sighed miserably.
"It's either that or a dress. Take your pick, and do it fast so I can narrow the selection down." Sarah was beginning to get annoyed. No matter what, he'd bitch.
"A dress, I guess. I can just pretend it's a really long shirt." It was so strange hearing her mom talk that way. I'll probably forget sh...he's not my mom, once he's in one of her dresses, She thought as she looked through her mom's closet for a suitable dress. Panties and a bra were already taken care of, sitting on the bed forgotten for now. Eventually she found several which were cut more like T-shirts, and one loose V-neck dress. She laid them out on the bed and gestured toward them for Biff to choose. "Doesn't she have any other colors? Black or brown or something?" Sarah hadn't thought about color. She just shook her head, gesturing once again, scowling. A few minutes later, he picked up a plain red dress which, Sarah knew from experience, would come down to mid-thigh. "Well, alright, I guess I'll pick this one."
Biff started to undress, and Sarah was so busy trying to ignore the sight of her naked mother that she forgot about the underwear, simply gathering his clothes up and dragging him back into her room. "Shit, I need to get you a nightgown." Sarah exclaimed, running back out and coming back just a moment later with a garment too frilly for Biff's tastes. "Take that dress home with you in the morning, in case you need it later. Wear this now." She thrust the nightgown at him, sitting on her bed and turning away.
"You can turn around now." Biff blushed, standing in front of her in a nightgown which barely covered his ass; his nipples were clearly visible from the front, too. He felt naked.
"You didn't put any panties on? Or a bra?!" Sarah cried, not wanting to go back in for them but unable to look away from the adult woman in front of her wearing nothing but a flimsy nightgown.
"No... you didn't give me any. I dunno how to put on a bra anyway." His blush intensified, and he sat down next to her in the same way he otherwise would. Anyone who came in would be flashed immediately, but Sarah didn't care to correct him. It'd hopefully be temporary, and the door was locked anyway.
A yell from downstairs alerted her, making her stomach growl. Dinner. "I'm gonna go eat. I'll bring you something back up, alright? Just stay put." Sarah hurried downstairs, leaving Biff alone with his unfamiliar and downright wrong body; the body of his girlfriend's mother.
