Becky Encourages You to Play with Your Cock

Becky is alone in her class studying hard when you appear. She is surprised to see you but then realises she recognises you from her chess club. As she talks to you about her work she notices you are growing in your trousers. At first she is shocked but she has always liked you so after a little thought she tells you she will help you out with the bulge in your trousers if you help her with her work afterwards. So you grab hold of your cock as Becky slowly starts to slip off her tight geeky uniform in front of you. She slips it off very slowly, not quite realising just how much she is teasing you. You play with yourself more & more as she shyly teases & strips revealing more and more of her perfect body, even slipping off her pretty lingerie so she is left completely naked apart from just her socks & pumps. It is then you can no longer contain yourself and you explode right there in front of her!
