Don't deny it, I just caught you spying on her. Your cock is still hard you disgusting little pervert. There's no point grounding you, that will just give you more time to peep on her. What you need is aversion therapy. Take out your cock and start stroking it. I know you already were. Spanking your ass will do no good so I'm going to spank your cock instead. Paddles, crops, rubber bands, anything that will sting that hard cock of yours. Keep stroking. This will be one lesson you won't soon forget. By the time I'm done you will never want to spy on her again.
