When I was 21 I hooked up with a hottie who's 24 and knew her for 5yrs and always wanted to bang her. All of the guys I hung out with in high school wanted to fuck her and I fantasized myself but knew I had no chance in hell so I never bothered perusing her. Well I guess I got lucky cuz I'm not great looking and don't have a big dick but do consider myself a great lover. Well so I hook up with her and sparks fly. She is great in the sack and I feel like the luckiest guy ever. Banging her eating her pussy and getting sucked off by her is my fantasy come true. We fuck 5 times a day she is so horny all the time it's unbelievable. 4 months into the relationship I become close to her little sister. She laughs at my jokes follows me around and talks about her personal life with me all the time. She becomes the lil sister I always wanted and I wind up hanging out with her and her younger brother as often and sometimes more often than their older sister who I'm living with and fucking. My girl sees the situation as 'cute' and believes me to be trying to build relationships with her family members and being a role model for her younger siblings which in the beginning it was. Her sister was 14 at the time actually 13 when I first met her. And she is smoking hot too. In a totAlly different way she has blonde hair big tits and a plump ass . My girlfriend was thin brunette and ppl compare her to Denise Richards . Her younger sister was more like Anna Nicole Smith. Anyway so I never had sexual feelings for lil sis until the day she told me she had sex with a guy at school. She told me he complained that she wasn't good at sucking dick and she wanted to learn how to do it better. I sat next to her with a chubby smelling her perfume and hearing her soft voice whispering this in my ear and for the first time I wasn't looking at her as a sister but as a potential lover. Within a week or so I made a move and she strokes my cock like her sister never did. Her wet cute twat was so tight I could barely last 3 minutes fucking her. She'd let me jerk off on her face she licked my balls and ass and fucked me so good it was surreal. We snuck around for months sucking and fucking each other behind her sisters back every chance we got. One day I was in our apt and lil sis just gave me some tight pussy and snuck out the window just in time before big sis came home from work. Before I know it big sis is sucking my still wet cock that was in her sisters cunt 10 minutes before and I remember thinking because she was bisexual-I hope she doesn't recognize the pussy juice on my dick cuz how will I explain myself. Well I wound up marrying big sis and were together 15yrs and hAve 3 gorgeous kids and a happy life. Lilsis has kept our secret all these years lucky for me cuz if it came out it would ruin my family. I don't see her often once a year for a holiday and summertime maybe but she still gives me wood every time she's near me. She turned out to be a mess, drugs and welfare and a deadbeat mom so I guess I picked the right sister to 'stick' with. My wife is still hot, makes 100k a year and sometimes when I'm doing her doggystyle she looks just like lil sis and I cumm like the devil and laugh myself to sleep!
