Tell us about your PARTNER(S). What did they look like? How well did you know them, had you hooked up before? How/Where did you meet them? How did you feel about them before the hookup? S is my wife’s sister she is 5’3″ jet black hair, brown eyes. I have known her for 15 years prior to our first hook up. At first we didn’t like each other but over time we started to tolerate each other, became friends and actually started to flirt through her husband I knew it had been 5 years since they had sex, and the idea of sleeping with my sister in law had defiantly crossed my mind.

How/where did the hookup BEGIN? What led to it? Was planning involved? Who instigated it? It was her 40th birthday. I sent her text wishing her a happy birthday. We exchanged a few text, she was not happy that she took the day off and her husband didn’t. I told her I would spend the day with her, I would take her to a movie and lunch. I stopped picked her up some flowers.

What happened DURING the hookup? What sexual behaviors took place (e.g., oral, vaginal, anal, kinky stuff)? How did you feel during it? How did they behave toward you? Were they a good lover? What did you talk about? How did it end? When I arrived and gave her the flowers she gave me a hug which lead to some kissing. She pulled away and started to walk away said no we can’t. I pulled her toward me holding her back to my chest, I kissed her neck and whispered why can’t we? Before she could answer I was rubbing her nipples over her bra still kissing her neck her breathing became deeper and her words were moans, “we are married” she turned around and started to kiss me. I picked her up carried her upstairs to her bedroom. Laid her on the bed took her clothes off and went right down and started eating her pussy. She had an amazing thick black bush slim pink lips with a nice pink button it wasn’t long she was screaming in pleasure. I stopped and started kissing her again my body between her legs she looks into my eyes ” I want to feel you in me”. Sill looking into each other’s eyes I slowly start to enter her. S pussy is incredibly tight I slowly push into her about 2/3 the way in she her eyes roll back and she gasp for air. I was blessed with very good girth and am just over 7″. I start to build a Rythmn with her and finally was able to give her all of me. I imagine S as a very conservative lover. Was I wrong, she was screaming telling me to Fuck her harder. I finished inside of her. She immediately started sucking my cock with our juices mixed together. She stopped and kissed me while stroking me trying to get me hard again. It didn’t take long and she she took her spot on top of me. She leaned in to kiss me again and whispered my turn to be in charge looking up watching my sister in law fucking me was truly a dream come true. She would ride me and stopped leaned down whispered ” I have wanted to fuck you since the day my sister brought you home”, and she started to ride me again. Fuck that may have been one of the most erotic things anyone ever said. Again she stopped leaned down to kiss me. With our lips touching she whispers “do I fuck better then my sister” and she goes back to a very slow Rythmn. Her words are sending me over the top. While riding me slow I look up at her and say “yes” she moans and starts to go faster. I am getting ready to cum, and yell out S you fuck so much better then your sister. This sent us both over the edge. She fell foward on top of my and I held her. Eventually felt my cum drip out of her down my thigh

She did give me a blow job before I left and took every last drop ( something her sister rarely does). We agreed this was our secret and we would not risk it again. 5 months later was my birthday and she returned the favor. We couldn’t just stop after that one amazing experience For the last 8 years we get together on or near our birthday to celebrate!
