so i'm fucking my 18 year old girlfriend on the couch. she lives with her mom. she's still in high school. i come over nearly every night to bone down after her mom goes to bed at 9 p.m. at first i tried to be quiet, but she told me her mom knows what we do and is ok with it, that's why her mom pays for her birth control pills and asks that we put a towel down before we screw.
her mom sometimes stands at the top of the stairs and listens to us, and peeps us in the mirror on the wall which reflects us fucking on the couch and the living room floor too. she stands there in her open robe, pinching her nipples and using a mini vibrator on her clit. the first time it freaked me out, i was buried balls deep doggy style in her daughter when i glanced up at the mirror and caught her eye. i mean, here i am, FUCKING HER DAUGHTER AND SHE'S MASTURBATING TO US AND KNOWS NOW I CAN SEE HER. awww fuck and gawdamn, that's hot and pervy. i love it. we made eye contact and my eyes got wide in surprise and i stopped mid stroke, thinking i was in some kind of trouble before i noticed where her hands were, she was getting off. she smiled a small smile and so i just kept on fucking her daughter.

fast forward 10 years (to be continued).
