My stepbrother and I share my friend's pussy

My friend told me she wanted to know what my tits tasted like. So I let her suck my tits. While she was sucking my tits, we got carried away and ended up scissoring each other's pussy. While we scissored each other's pussy I caught my stepbrother jerking off his cock while watching us. Later that day, my stepbrother and I had a bisexual threesome with my friend.
