This happened a couple years ago, I was 19. I had been seeing this girl for a few months. She was a short and stacked blonde, about 5’1 with some serious curves. The sex we had was always amazing, and she would get really loud in bed so I would always have to take precautionary measures when we would fuck while her folks were home.
One day, I went to her house to pick her up for a picnic that we had planned. Her mother answered the door, and she is even more stacked than her daughter. It’s hard not to look at her face without glancing down at her huge tits. Anyways, my girl and her father were gone, apparently there was some family emergency and they had to leave, her mother wouldn’t go into much detail. Of course this bummed me out since I was looking forward to spending the day with her, so her mom offered me to come inside, and we just laid out the picnic I had planned in her living room and had a chat.
We talked a lot about school at first, our senior year was about to end and we were excited about going to college. Eventually the topics became more personal, she got curious about our sex life and then admitted that she would sometimes listen in on us fucking, and that listening to it turned her on. Of course I got a raging boner immediately after hearing that. She then asked why her daughter was so loud because she herself was never that loud when fooling around with her husband. Now, here’s where you should know, I’m pretty well hung, actually very well hung, usually quite noticeable. I “adjusted” my boner in my pants to feign me being uncomfortable, and she looked at me with a cheeky smile and said “oh, did I do that”, to which I responded I think you know the answer to that.
Her smile got even bigger, and she then placed her hand on my leg and asked me to pull it out, which of course I did. She let out a very long breath and an elongated “ohh myy godd” when she saw it, and we proceeded to have maybe the best sex I had ever had up to that point. Her throat was amazing, she couldn't take me super deep and didn't want to get too messy with her spit, but she could really use her throat muscles to milk my dick. After that, we fucked in several different positions, cowgirl, doggy, pronebone, etc. It took her a minute to get adjusted to my size, something clearly her husband was lacking, but once she did, she took it even better than her daughter and was actually even louder than her daughter. Watching her fat ass ripple and huge tits swing wildly as I fucked her was incredible. I came 3 times, she came idk how many times. I eventually broke up with her daughter after our first semester of college, but the whole time I was still with her and fucking her, I would take every chance I could to fuck her mother, and to this day I don’t think she knows about it.
