When you get as fat as I am it becomes important to try new positions and things. My boyfriend is lying on the bed watching me and I come over to him already nude. I rub on him and tease him a bit the get on him to ride him. The edge of the bed works great for me and I can toss a leg up and he can still be inside me and grab my fat too! I grind my fat pussy on his cock and ride it until I get exactly what I wanted, a big orgasm!
