I [f]uck my sister in law like we’re [m]arried.

I want to begin this story by stating that I am in an open marriage and everything detailed here is completely consensual.

I fuck my sister-in-law, probably more frequently than I do my own wife.

She is my wife’s half sister, they share mothers, and luckily for me she does not find our sexual relationship to be off putting at all. She’s even confessed being turned on by it, but that she would never want to watch us or join. I completely understand that.

It all began when she moved in with us. My mother in law is extremely religious, culitishly so, and her extreme religious fervor has driven all of her daughters off. I will call her Lynn here. Lynn is the youngest and last of the three sisters to leave the nest with a bad taste in her mouth and a desire to be naughty and rebellious.

Lynn is 25 now; she moved in three years ago. We enjoy having her with us for the obvious economic advantage it provides, and she is helpful around the house as well. We are less stressed having her help, and of course, I am less stressed because her and I enjoy a healthy sexual relationship.

It all happened rather fast. It wasn’t long after she’d moved in that she grew curious about how my wife and I handle an open relationship, and it lead to many discussions. Those discussions got hot very quickly, and Lynn is a girl that says what’s on her mind, as well as an extremely horny, sexually curious person.

One day it was just her and I talking, and I was telling her about a recent date. We were very flirty and frank during the discussion, but she said something that surprised me.
She said, “I wonder if (pseudonym) would let you fuck me.” I was floored. After determining that she wasn’t joking and that she’d actually follow through with her offer, I sent my wife a text. She responded: Go 4 it ?

Ok. I was living a real life porn. I took Lynn to the bedroom, clothes were quickly shed, and we jumped into the sheets together.

So my wife is half Asian, and Lynn is full blooded mixed Asian, a mix between Filipino and Chinese. She’s small and tight. The combination of the novelty and excitement of the situation and her very tight pussy made me cum pretty fast. No… a condom was not used. She is on BC and I actually trust her health status. Nothing felt more amazing than giving my little sister in law a creampie.

That one frolic has lead to an ongoing arrangement. I sleep with her, sometimes all night, just like I do with my wife. We are convivial to one another, and I kiss and cuddle her as though we are married.

I wanted to post this because I’ve had people ask, and now I can just link them with this post.
