My wife, her step sister Crissy Cox and I spent the day at the beach while she was in town and I couldn't keep my eyes off her 19 yr old tits that kept trying to pop out all day. We were watching a movie and my wife went to bed. Crissy had noticed my stares all day and was feeling playful. Claiming she was bored with the movie she suggested we fool around. Even with my wife just down the Hall I couldn,t resist this hot girls advances. She oils up my shaft and jerks me off with a devilish grin on her face. She promised she wouldn't tell her step sister so I hope she visits again soon.
