An open relationship was your idea since you thought she may not be satisfied enough, later that night you got this sent from your Bully, she does really love you but her friends don't stop talking about how good his dick is.
Your bully is a muscular man and eventually your sister went to talk to him bout not to bully you anymore and your sister is now being fucked by him while they’re kissing by the pool and you’re at home like a cuck
When my mom and my bully see me watching them fuck in our house, they order me to go and keep mommy’s legs up in the air. I’m so excited to help mommy get fucked
