Biff embraced the new male Sarah, keeping her close, then began to rub her, actually feeling her up.
Sarah pushed him away.
"What?" Biff asked.
"You're getting off on this, aren't you?" Sarah asked.
"What? No ... I ..."
"You just said before that you thought you were gay. I think this proves it," she said, pointing down at Biff's crotch, where a bulge could clearly be seen.
Biff blushed. Then he cleared his throat. "What difference does it make, anyway?" he asked. "I love you, not anyone else. You're the one who changed. From your point-of-view I haven't changed at all. I mean, as far as how I feel about you."
"I ... I guess you're right. But it still feels strange. Doesn't it?"
"At first. But the more I look at you, the more I feel like being gay is right. I know that sounds strange, but it's how I feel." He brought Sarah closer and embraced her again, feeling up her new masculine body. She was right. Her new body was a turn-on for him. His manhood began to get stiff again at the feel of Sarah's new muscular and manly body.
Sarah still felt awkward (beyond the fact that she was a guy now), but she let Biff hold her. Right now, she needed his comfort.
