Not Shocked

I love my sister a lot, but she has always made questionable decisions. She never admits it but I know she crushes on me even to this day. When we were teens, we secretly ended up having sex a few times but my cock was too big and painful. We stopped after our parents got us involved in religion. Funny enough it never stuck with me but my sister became a religious nut job. Unsurprisingly, she had terrible taste in men and got knocked up. In came my niece and I watched her grow up over the years.

Last summer things went south in my sisters life and she needed a place to stay with her daughter. She didn’t want to bother our parents so I offered her to stay at my place. I never married and did well in life, so it was no bother for me. Long story short we ended up having sex again. Didn’t take long for my niece to find out, I’m sure she could hear things from her room. My niece is a lazy bum as well. She’s bigger than her mom, and acts like a snob. I knew she was messing around with guys, sneaking out at night and playing with herself on the phone. I ignored it for a while but things turned around after she found out I was in her moms bed. She was nicer, flirty, and seductive. I couldn’t believe it but I went along with it because she was acting more respectful. Eventually we started having a good relationship and she actually looked up to me as a great uncle. That is until she offered to suck my cock while her mom was making breakfast one morning. I have a high sex drive and couldn’t help it. She was laying on my lap watching tv when I felt her soft hands grip my trousers. I was hard, watched her massages my cock while pots and pans were cooking in the kitchen. I pushed her away a bit but I gave up when she lifted her shirt exposing her ass and pussy. She gave me the best head I’ve ever had. I pushed her off before I came and went to my room to clear my head. She followed and rode me on my bed. I couldn’t believe how easy, wet, and slippery her pussy was. She took my dick in whole and never buckled. We stopped fucking when we heard her mom scream breakfast was ready. She recently went out of town and I’ve been having sex with her daughter this whole time. I have her run around naked and tell me stories about the guys she’s fucked. Turns out I wasn’t her first big cock.
