I just found out my stepfather, who is Black, has been fucking my wife for months, and now she is pregnant. She says she’s keeping the baby. [cuckold]

My stepfather started flirting with my then-girlfriend the first time I ever brought her home to meet him and my mom 3 years ago.

I just thought he was being nice, but now I've found how he's been fucking her secretly while I'm at work almost every weekday since last Thanksgiving. All during this time, she's been rejecting my sexual advances saying she's too tired or just isn't in the mood, and tells me to go jerk myself off if I'm that horny, but she doesn't want to see or hear me do it.

She told me over text that not only is she keeping the baby, but she's going to continue fucking my stepdad while keeping me pussy free. Only now, she feels no reason to hide anymore and so he's been over at our apartment to fuck her at all kinds of random times in the early mornings and late nights when my mom is unaware.

Hearing them fuck makes me cum so hard and I've taken to being right outside the bedroom door so I can hear them better. Hearing her moan and scream and her wet pussy make those gushing sounds while he pounds her hard drives me wild. But then, when he grunts and growls and fills her up with his cum, my little cock usually explodes seconds after.

I've found myself fantasizing about licking her pussy clean after he's finished with her, and she said would let me as long as I didn't try to fuck her, and of course I agreed. I've done it a few times now and it turns me on like nothing else ever could.

I'm not sure what to do here. I'm massively humiliated and turned on by the situation, but I'm also scared about how my mom will react when she finds out who the father of her grandchild is when it's born.
