I did it with my sister-in-law

Hello...
Back with some of my experiences...
About two months ago, we went to visit my sister-in-law for a month. One night, the three of us went to the house of one of her friends. There, between drinks, my wife got drunk, and I took her home and put her to bed.
After a while, she slowly entered the room, put her hands under the sheets, and grabbed me. I opened my eyes, and she gave me an intense tongue kiss that I'll never forget. It went all the way down to the back of my throat, and she whispered in my ear...
'I want to do it with you, brother-in-law...'
I slowly got up, even though I had a fart that could wake up a bomb, and went to her room.
Despite her age, my sister-in-law is re-fuerte, so I took off my mini-boxer shorts and gave her a blow job like no one ever did before then. We fell asleep, and she said... 'Do you want to suck me?'
I didn't think for a second with pleasure, lost between her legs, and stuck my tongue all the way down her throat, I think.
We did it for hours, never doing it before, and even found some new positions... jjjjj.
Then I went back to my room...
Since that day, our relationship with her has increased, we've gotten closer.
The same thing happened on another occasion too, I hope to go back soon and have those escapes again, there will be more, since she knows that with my wife once in a while.... and one of flesh is...
