Looks like he's found one way to direct Professor Rammsteiner into doing what he wants. Jade allows his hand to be shaken off, focusing on meeting the strokes of Professor Rammsteiner's hand with a few slight thrusts, a little tentative as he tries to figure out what would feel the best.

Not that he has much time to figure things out. Soon, the hand on his cock moves lower. Jade draws in a sharp breath, his mouth feeling dry with anticipation. He doesn't have to think before answering: "Yes."

Jade thinks he understood what Professor Rammsteiner meant by this, but he isn't exactly sure. It doesn't matter. It'll be something new, so he's interested. If he doesn't like it, it's only a matter of telling Professor Rammsteiner to stop.
