Compartilhar um banheiro com a madrasta e se masturbar juntos termina em sexo anal e gozada interna

It was the Fourth of July and we had to wash off after the pool and we had to share a bathroom to do it. I thought it would be ok if we left our bathing suits on but that didn't stop either one of us from masturbating. I noticed him watching me and it seemed like we might as well just use each other for sex and get on with it. I was super surprised when he put his dick in my butt hole but I didn't really mind.
