My wife is pretty vanilla and prudish in bed. We usually have the same routine, I rub her clit until she feels like she will cum. She climbs on top of me and dry humps my hard cock until she has 2-3 orgasms. By then she is usually really into it and I finger her with 2-3 fingers while she kisses my neck area until she grabs my cock to signal me to penetrate her. About 3 weeks ago instead of grabbing my cock, she asked for more fingers and rolled on her back. First I added my pinky, then my thumb. I pushed to the top knuckle, but couldn’t get my hand in. She was moaning and pushing against me. I told her that I loved trying to fist her and that it was definately a fetish of mine. I asked her if she was only doing it for me, and she replied that when it comes to sex, she doesn’t do anything “just for me”. Anyway, I took that as an invitation to try to push the envelope last night during sex. The situation was almost identical to above, but when she rolled on her back to be fingered, I grabbed the lube and covered my fist in it. She didn’t stop me in anyway. I was excited beyond belief. I have wanted to fist her for years (I blame the internet for this fetish). Anyway the lube was amazing. I was beyond the knuckle almost right away. The feeling of her labia wrapped around my hand was insane. I was able to go wrist deep before she asked me to pull out! I have a feeling I will be fist fucking her in a few months. I can’t wait to hear her moan! It is so hot to know that my petite skinny wife is a secret size queen. I will keep you posted if I succeed in fucking her with my fist soon.
