My GF is about as vanilla as they come. However, getting her to agree to do a few more progressively kinky things over the last year or so has been a massive turn on; more than having a willing kinky GF, in my opinion.
1st thing she did was wear a very tight and short black dress with no panties underneath and 5″ high heels for my birthday dinner last year. She took me to dinner at a fancy restaurant and every guy’s head was turning, random guys were even yelling out car windows lol. Every time she uncrossed her legs I could see the little-waxed spot right above her pussy. Needless to say, we fucked like rabbits when we got home.
2nd She agreed to dress up in lingerie and let me take pictures of her. She even gradually strips down totally naked, just wearing high heels and stockings. I think it turns her on to know I masturbate to those pics whenever she isn’t around.
3rd She agreed to let me fuck her in the ass on special occasions like my birthday and Valentines day. Her butthole is so cute and tight it really takes some work to get my cock in there. It feels so good when I’m balls deep and cum deep inside of her.
