Pull your trousers up.
Put that stiff cock inside. Make sure it is pointing straight up.
Now go into the room where she is.
Ask her if she knows where there is a pen. You can think of a reason!!
Make sure she doesn't see your bulging pants!
Walk around for a few moments. Think about me in here, next door, feeling horny for you.
Then walk to a different room and have 40 strokes. Fast. Then come back to me.
