Tonguing my brothers wife’s ass[MF]

Went over my brothers apartment the other day to hang but he had to take off cause he was called to something last second. Was just me and sister in law and she said I was fine to hang around and we chilled together for a while; we watched to tv and shared a joint. Then she said she was going to hop in the shower but after she did I got the rumblies BAD telling me I had to use the toilet soon and it wasn’t gonna wait for her to finish. I went in apologizing and saying I had to go; she’s pretty chill and open minded on most things but I still wasn’t sure how she’d react but she said it was fine.

Sat there going right next to the bath and we talked pretty casually through the curtain as she showered, occasionally poking her head out. My heart stopped when I heard her shut the water off and I wasn’t quite done. She said aint that big a deal and got out and started drying her wet naked body off literally inches in front of me. Did my best not to stare but she could tell I was. Worse was I had to wipe and the TP was on the other side of the length of the tub, on the other side of her. I awkwardly started reaching for some and she started teasing, moving over partly in my way as she dried just to tease, even thrusting her pussy towards my arms and bending so her good sized tits blocked my view.

The nerves subsided and we sorta laughed it off as I was done and just waiting for her to finish (getting up would have been a challenge with how my erection was wedged against the toilet bowl at that moment). then she bent straight over in front of me to dry her legs, don’t think she was playing this time, and inches in front of my face I was staring at her whole undercarriage displayed. Seeing her pussy lips and asshole so displayed drove me wild(I love any kind action involving the ass) so I got real bold and literally looking in her ass, asked if my brother ever ate her ass out.

She got quiet and I panicked thinking I’d gone too far but then she just casually answers no, they do anal sometimes but never eating ass. I said I love it and im great and I’d be happy to do it for her. Again she gets quiet and I worry and she just says, ok, why not, im offering and she just showered so I know she’s clean. She bends over to brace against the side of the tub and I kneel behind her, spread them cheeks and just dig in and it was great and I could tell she was enjoying it cause she started wincing and moaning pretty quick and her inner thighs started to quake. Enjoyed brushing her nipples and pussy lips with my fingers as I kept going, she didn’t seem to mind. She even moved her foot back and started rubbing my hardon with her toes and her hand reached back to clutch my hair and push my head in her ass more.

She came and squirted on the floor twice and asked if I was close to cumming; I said yes and she said I could put it in her ass to finish. I did and I t was nice and tight and didn’t take more than a few pumps to finish and we just wrapped around each other quaking for a minute. She said thanks and it was great and to go chill cause now she needed another shower to clean up again. That night she sent me a text saying don’t know when or if ever that it might happen again be she enjoyed it and thanked me. Also sent me a couple sexy nudes to hold on to as a thank you.
