On the day when my parents were away on a trip, my sister-in-law invited her friends over for a sleepover! When I went to check on them because it was too noisy late at night... they were all having a pajama party in their defenseless, bra-less state! When I was bewildered by the erotic scene, I was forcibly made to join in their girl talk... and because I could see the nipples peeking out from the gaps in their pajamas, I got an erection... The sister-in-law's friends, excited by the erect penis, decided to see who could feel the best and ended up in an erotic scramble to grab the penis!
