You stalk Yang all over the school waiting until she's finally alone to try your luck. Eventually she goes into the girls restroom and after making sure no one else was there you put up an out of order sign and get to work. You put in a ski mask and hide in the stall a couple stalls away and wait with your cock already getting hard just thinking about what you have planned for her. She eventually walks out of the stall and washes her hands seeing your moment you open the door and run up behind her pushing her against the sink.

Yang-"What the...!? Who the hell are you asshole!?" She says with her crazy strength making it hard for you to hold her for much longer.

"Stop that you bitch! Unless you want your sister to get hurt! My boys have her all tied up and they really want to break such a cute little thing like her so unless you do what say she's going to become a women very soon." You say to her lying of course about having her sister but she doesn't know that and she quickly stops struggling

Yang-"What have you done with her you bastard!?" She yells semi struggling but now not as hard or as forceful as before.

"Nothing.......yet and it will stay that way if you do what I say." You say with a grin under your mask knowing you've got her. Yang stays quick for a couple moments before responding

Yang-"What do you want then..." She says now somewhat calmly although still with a pissed look on her face.

You smile evilly again and you push your crotch onto her big spandex assed shorts allowing her to feel your hard cock between her ass checks

"I want your body Yang you fucking cock tease!" You say lustfully
