Consideration

Wally could have asked Willow for a titjob right then and there, but...well, he was sure she was a virgin. And he wanted her first time to be special, of her own accord. However, he also knew Willow would only want to fuck her boyfriend, so...

"I'm so glad you agreed to be my girlfriend, Willow," Wally said as he kept feeling up her tits.

"Uh-huh," Willow moaned. "If you weren't my b-boyfriend I wouldn't let you d-do this!"

Once Wally was satisfied, he had Willow get redressed, sans bra, and the two of them walked arm in arm to their next class.
