An Affair With My In-law

I've been married to my wife for 4 years and we have one son together. Two years ago, my wife had just had our son and she couldn't have sex. Her younger sister (my sister in law) had been staying with us to help my wife with the baby. My wife had went to bed early and one thing led to another and the sister and I ended up f**king.

We have kept this affair up since that first night in my living room. My wife's sister has enrolled in UNILAG and has been staying in one of the apartments around school. Every day during lunch I go to visit her and get a blowjob or f**k her. She and I have formed a master/slave relationship and she loves to do all the kinky things my wife wouldn't dream of. She let's me spit on her, f**k her ass, piss on her face, everything.

About six months ago, I threw out the sister's birth control. She told me how much of a turn on that was, so I f**ked her and forced her to hold all my cum inside her so that she would become pregnant. It was hot and she loved it. We did that over and over again until she missed her period. She went to the clinic and took the abortion pill because she didn't want to ruin her life. I supported her decision and she and I kept it quiet.

Since then, she and I have kept up the same affair (this time she is using birth control). Every day I go visit her, cum in her, and leave. Sometimes when my wife is away, the sister comes over to the house and we have fun. Other times, I leave her a cup filled with cum so that she can put it in her pussy and send me the photos.

I want to feel bad, but I don't.
