There she was lying on her back with her legs spread wide apart moaning away as my uncle pounded her pussy from in between her thick thighs. The sight was so remarkable, my mom, taking a cock up her cunt, getting fucked by her own brother in law. I had just come to get my assignment which was due that day. As I entered the house I could hear her moans which got me so excited, so I just peeked from the crack in the door. I could see them both sideways with my uncle on top of my mom fucking away. My mom's nightie was pulled up and her top buttons were open so her tits were hanging out for him to suck on. It was a quickie, they wouldn't try this for a long time. I also realised this and ran in to get my digital camera and got a few nice close ups and good shots of this erotic scene.
I couldn't get my mind on anything the whole day. I jacked off, then again I jacked off and then again I did it. I was so horny looking at the pictures, seeing my mom spreading it our for someone other than my father. Well I didn't blame her, my father was out on his job trip for more than a year now, it must be making her horny and the closest was my uncle who would visit once a month to get us things we needed.
The effect of the pics started wearing off after a while as I craved for the real thing. Well I had the pictures and they could be used.
So I waited for the day when she was angry on me for some reason, I would have to get her angry so I could get myself to hate her so much so as to blackmail her. She was upset about the money I lost and I thought this was a good time to spill out everything.
After dinner as she sat to watch tv, I went in and got the pictures and threw them in front of her. She was so stunned that she didn't say a word. She was just looking at me and I knew she understood what the consequences could be.
