[MF] My Sister in law is my Kryptonite

I am in my 30’s and married for over 2 years and never met my wife’s youngest sister until this year. Their entire family is in Asia except for my wife and her youngest sister.

My sister in law just graduated highschool and spent a year off in her home country and her family wanted her closer to my wife and I so she was sort of dumped on me to house until my wife could find a place for her to stay.

I have only seen childhood pictures of my sister in law but nothing recent so imagine my surprise when I had to pick her up from the airport as my wife had to babysit my nephew.

If my wife was a 7 or 8 depending on clothes/makeup her younger sister was a dead 8 or 9. It was like looking at my wife if everything physically was improved 2-5%.

They looked very very similar I just want to stress that it disturbed me in a way that confused the hell out of me. I could look at a girl 10/10 and enjoy the view but go on my merry way without another single thought and never feel tempted.

I find my wife very attractive to me and this is why I told myself I would never cheat and my life I meet attractive clients all the time. She pierced through that wall the moment I saw her smile at me when she recognized me. This is where my brain gets confused. They both are so freaking similar except she is what my wife would have looked like if she was as addicted to health and exercise and kept up with clothing and makeup trends.

Hell it was an awkward couple of weeks because she was just so outgoing so it was easy to get into conversations and fall into that familiar brain fuck that was comparing nuisances between her and my wife.

We have a pool in the apartment and my sister in law wanted to try it out and she asked me drop her off at the closest mall for her to find a bikini and I being thoughtful suggested she raid my wife’s closet not insinuating anything I swear. She asked for me and I suddenly felt nervous because I recognize the internet ordered bikini she had in her hands and fought like a mad man in my mind over suggesting a safer bikini instead but I felt the blood in my ears when I approved of it knowing my wife even fears wearing it outside the bedroom.

Apparently as trendy as she was she never wore thong bikini bottoms in public let a lone in front of anyone else. I suggested she get changed down in the change room and she told me she wanted to try it on just in case it might not fit her. I knew it would as it fit my wife perfectly and my sister in law was even more fit then her. I could hear the blood pumping in my ears the moment I realize she was wearing it and that if I wanted to I could invite myself to join her down there and see just how well it would fit. I decided I wouldn’t and turned on my game console to distract myself.

The door opened and she is next to me wearing it…wearing IT and I forget to hide any kind of reaction and threw compliments at her non stop. I don’t know why she was standing like this in front of me but I made the life changing choice to stand up and put my arms around her lower back and digging my hand into hair and pulling her head back to kiss her. She is left standing biting her lip not looking me into the eyes for whatever thoughts she was fighting with who knows.

I remember pressing my thumb against her breast to feel the nipple poking prominently against her bra watching her stunning face react to me and her body tremble and hear her gasp. I presummed a lot then. I gave her moments to decide and she followed my tug of her hair to her knees and lowered my pants and freed myself for her final reaction. I watched her eyes stare at it and I hoped she would look tempted and even felt a bit worried she would recoil from it but she did not. She just told me she has never done this and I let that sink in for a few moments and decided for the both of us.

I let my mind fog over enough to push the shame and guilt that was building and pulled her forward and her lips parted and the heat of her mouth finally came and as obviously inexperienced as she was with oral her stunning face just made the moment intoxicating. I wanted to cum soon and hard but I was able to stop her and push her back before I was going to cum. She had a look of surprise and confusion but I got her on to her feet and in a blur I entered her from behind with her bikini pushed to the side. I had her lower herself so that I could enjoy groping her chest before grabbing her arms and finding the strokes to took her to an orgasm then standing over her and painting her with my cum.

I felt great for a long time that day and found out about her inexperience and who doesn’t want to hear that it was the first time she came during penetration so that was the glaze on that lust filled moment in time. She apologized before I even thought of apologizing admitting she was curious about me because of the way I kept looking at her. She didn’t expect anything to happen and of course we agreed it was just today. Or more like she agreed to my request and we spent the rest of the day we had alone together having sex.

This was both great but exhausting to a mental and physical level. She didn’t dare wear the outfit in public though and hasn’t gone swimming yet.
