If you want to deny that you were perving on someone it helps if you don't have a little boner tenting out of your shorts. Sam thinks he can bluff Penny into believing he was not spying on her in a bikini but she grabs his hard dick as all the proof she needs. Sam tries to twist out of her grasp but that just makes it easier for Penny to get a grip on his undies for a nice wedgie. Since he got to check out her ass, she is going to wedge his undies in his ass. Once she has turned his boy panties into a thong/handle, Penny bends him over her knee for the kind of hard spanking every Peeping Tom deserves.
