Like the title suggests, my sister in law is an absolute smoke show, a curvy build and enormous tits. My wife and I live on the same block as my sister in law and her husband, but we are constantly in and out of each other's houses and always bumping into one another. We've all kicked back and had one or two and gotten pretty loose and her wild sexual nature gets brought up and of course it made my mind go crazy with the thought of the forbidden fruit. I've done my best to keep my thoughts to myself but she flirts and it doesnt help at all. Today was one of many instances, we were speaking after i came home from work and i ran into her, we were joking back and forth and smiling and she mindlessly raised the bottom of her shirt up and itched her stomach but revealed a perfect shot of her undertits. She caught my gaze and i coughed and covered my tracks as best as i could, but she winked and bit her lip before turning around like a school girl and walked away with her perfect ass waving goodbye to me. Her laundry is everywhere in her house and I've been thinking of snagging a pair of panties to keep for myself. You just never know who has cameras set up around the house and I'm not looking to cause a divorce or two, but any advice or conversation about the subject would be helpful!
