I recently got into a sticky situation with my SIL. Wife was at work and she asked me to take something over to her sister’s house. So off I went to drop off said item and she invited me in for a drink while I was there. So we’re sat there on the sofa chatting and she started to gently rub my leg with her foot. I immediately got rock hard because I have a foot fetish and her feet are amazing, she noticed the bulging in my jeans and smiled at me before rubbing it with her hand. I don’t remember how it happened exactly because it was so fast but before I knew it my cock was in her mouth and she had her tits out and they’re fucking massive. Seconds later she’s naked and on her back with me pounding away at her soaking wet pussy. Couldn’t have been more than a couple of minutes before I was about to blow she immediately told me to pull out and cum all over her 38 GG tits. I exploded all over those huge boobs of hers. She disappeared into the bathroom and came back and told me to go and we should just pretend this never happened. Problem is it’s been a week and I’ve not been able to get it out of my head ever since!
