Shower masturbation encouragement

Description: I'm taking a shower when i noticed you staring at me, dick hard... basically spying on me. i want to help you get that dick of yours even harder, so i start teasing you and playing with myself prompting you to jerk off for me. i want to be involved in your jerking off sessions, alright? actually, if you release a big load for me, i'll give you a little “prize”... a surprise, if you will. now let me countdown from 10 and let's see if your balls are as full as they look.
