PARATHD-4506 - My girlfriend's twin sister looks exactly like her, so I decided to see if they're the same in bed with a 3P sister sandwich!

Living together for six months, I was getting bored of the daily routine until my girlfriend's twin sister showed up. With her looking exactly like my girlfriend, I couldn't stop dreaming of a 3P. After some drinks and intimate questions, things get heated with a blindfolded game to guess who's who. When I start having sex with my girlfriend, her sister can't take it anymore and joins in for a wild 3P session.
