at 18 I lost my virginity to an older woman, who simply sat on my lap and got me ready then did it with me whilst taking it through her back door. she was taller and big in all the right places, this made her quite a handful for me as I was a super skinny young man, for the second time she sat on my chest as I lay on the sofa and then lay on top of me whilst we did it again, after that she sat on my back and I gave her a little pony ride. After that night I have always wanted to relive that experience, I am too shy to ask my girlfriend to do all that to me. Do I have a strong fetish for being sat on my big bottomed women or something?
