Bro, let’s just go at it and have sandwich baggie sex; it’s not like we’re into each other and planned it, right?
A sex position involving two girls and one guy. The two girls scissor eachother while the guy's penis sits in the middle creating an amazing new three way.
Dude! Me and Sally were goin' at it in her twin sister's bedroom when her sister walked in, got naked, and started scissoring each other with me in the middle! It was the best Sex Sandwhich ever and SUCH a porn moment!
