I don’t know what it is about my wife’s younger sisters. They just ruin my brain. I’ve already had sex (the best sex I’ve ever had) with the older one (23f). Now I want the younger one.

She’s a tight little brunette with big tits, a tiny waist and a perky ass. I have seen her naked but she doesn’t know that I saw her playing with herself.

She’s expressed some interest in me in the past but, I also get the vibe that she doesn’t want to betray her sister. I’ve already tried coming onto her a little and have received mixed messages. I don’t know how to progress the situation because the tricks I used to seduce the other sister are unlikely to work on the younger one. I don’t know if I should send an accident dick pic. If she tells my wife, I’d be in loads of trouble. I just don’t know.
