Sundays Playing With Fire

My sister in Kay have been hanging out this season watching the nfl games. My wife’s brother hates football and my wife could care less. Kathy likes my teams rival and also plays fantasy football. Our significant other could care less and think nothing of it. After the first week we started to bet. Kathy is a few years younger strawberry blond. Very cute face nice fatty tits but could use a little larger ass. I’m an ass man and she knew this. We made a few side bets after week 1 and while watching the games and hanging out. Our spouses decided that they could leave and do whatever they wanted. After a few drinks Kathey went into the restroom and came out in her team jersey only. It was short and I teased her telling her she needed more ass to fill it out. She raised her jersey up and showed me her rear. It looked good. I told her what I really wanted to see was her tits. She came close and raised her jersey exposing the 2 biggest tits I had ever seen. I grabbed them and they were so soft. I rolled her nipples in between my fingers. She let me suck them and finally let me tit fuck her. We did fuck but to be honest her blow job skills are killer. We watched the afternoon game together she spent most of the first half on her knees and I spent the second half licking her clean. She had never had anyone spend so much time rimming her ass. She enjoyed it. She has this fetish with cum in her mouth. She admitted it’s always been a big turn on for her to have a big load in her mouth. She then proceeded to tell me how many guys she has sucked and some where recent form work. As of now Sunday start early and when the spouses leave I face fuck the life out of her. We started hooking up during the week as well.
