"I'm sorry Ms.Humplen I thought this looked goo on me, don't you think so?"
"That is hardly the po...." She starts but you interrupter by exposing your nipples to her.
"Or are you saying I'd look better if I took it off?"
She tries to regain her composer but she can't take her eyes of your breast.
Taking advantage of the opening you step up to her and whisper in her ear "If my outfit is such a big deal why don't we meet at your place after school to discuss it in private." and just before yo pull away you plant a quick peck on the cheek.
She's so stud she can barely speak. "Um...uh...sure lets do that...ye..yeah."
Ms.Humplen quickly walks away trying to hide her blushing face.
