I fucked my cousins girlfriend

I was in my early 30s at the time. My cousin was living with his girlfriend and i would go over her house on a regular basis and we did a lot of drinking then. My cousin was a alcoholic and would get so fucked up he couldnt even get hard and have sex with his sexy girl. after about a month of going there she started to get real flirty with me and i would go home and jerk off thinking about her. one day i got the balls to call her at work and i told her that i wanted to fuck her brains out! i thought she would tell my cousin but she never did. later that night when she came home from work she called me and asked me to repeat what i said to her on the phone. at first i thought maybe my cousin was listing in and she was trying to set me up. I told her that she really turned me on and i wanted to fuck her. I told her we can meet at a hotel any time she wants. all she said was why a hotel when i have a house. I took that as a invitation that she was interested.
The next time i went to her house i brought a bottle of whiskey because i had a plan. I made drinks for my cousin and they were strong drinks! He almost drank the entire bottle before her passed out. when he did i got his girl to go into the laundry room and had he get on her knees and shoved my cock in her mouth. I ended up coming all over her face that evening a few days later i went there when he was gone and fucked her brains out which i did many times. he did end up almost catching us. he finally found out i was plugging her and moved out. pretty much ruined our relationship. I still see her every once in awhile just to fuck her.
