My Brother-In-Law

I needed to tell others why and how I got involved with my sister's hubby. He won't leave my sister because she's a bit older than him and I'm as young as him. My sister and him been married not too long. He married her for her very big long saggy tits that he enjoys groping and screwing. I'm small chested and sort of heavy built. My sister let me live with her and hubby sharing costs. My brother-in-law was more interested in sharing sexual activities since my sister wasn't into oral sex. I heard him and my sister argued over oral sex.
Then one day I had my bedroom door slightly open watching porn. I didn't know he peeked in but found out he did. I decided to be naughty so when my sister wasn't home I put in my porn tape and left my door wide open. The person in the porn asked the fat girl in the film to suck his cock as he shoved it in front of her face. I knew brother-in-law was peering in. I said out loud " O.K. " and shoved a dildo in my mouth and pretended it was real.
I opened my top exposing my huge areolas and ran the dildo across them on my chest. I freaked out brother-in-law when I told him I'll give him head if he stepped in my room. " You out do your sister's size areolas. MMMMMMHHHHH ! " as he pulled out his dick and slapped them with his cock. I held his cock tight and lowered my mouth on it. " Suck it and make it fill your mouth. " He started humping my mouth and his cum dripped out onto my hands which was running all over my chunky body. My fat thighs caused him to screw me hard while I held my legs apart and he lowered his face in my snatch and lapping my juices with his tongue.
I secretly prefer brother-in-law for sex he's endowed.
