This happened to me very recently and is a true story. I visited my doctors just to get a prescription signed about a month ago.
When I arrived I discovered I had been assigned a new doctor "Dr Evans" will see you the receptionist told me, I waited for my turn and entered the doctor's office when requested. To my surprise Dr Evans was a woman, a very attractive woman at that. She was shorter than me but much thicker and obviously much heavier (just my type) as I took a seat at her desk I noticed she had a picture of a ladies rugby team on there and also some rugby related memorabilia on the wall including a rosette and some certificates alongside her doctors degree. I said "ahh a sportswoman I take it?" I must admit I was quite turned on by her already "how did you guess?" she replied, "well apart from that group of wholesome young ladies in that photo it's your great physique" I said. Now if she was "in the club" (also a lesbian) she probably would have said so at this point, that's kind of our code but she didn't she just smiled and looked a little embarrassed, hmmmmm perhaps she's curious I thought. Anyway we chatted for a while and she asked me lots of questions to update my records and familiarise herself with me, one of the questions was about "lady problems" and how badly I suffer from them. Funnily enough I had a little pain that morning so I told her and she asked "have you tried applying pressure to it?", "to what?" I said, "to your lower stomach, sometimes applying a little pressure can help to ease the pain" she said! Wow I started getting a little turned on just by the fact her beautiful mouth had uttered the words "applying pressure" so I placed my hand on my stomach and pressed a little "like this?" I said. She got up and walked around her desk and placed her hand over mine and lowered it slightly then applied some extra pressure just with her hand but my god was she strong! I even had to say it out loud "my god you're strong!" she smiled and said yes but is it better? It really didn't make much difference and I wasn't in a great deal of pain to begin with but I played along because I was so turned on by this. "mmmmm yes that does feel better" I pulled my hand from under hers then put it on top of her hand and moved it slightly lower and said "try here". She pressed on my stomach with her hand again and I actually saw her tricep bulge a little through her blouse as she put some weight into it. I let go of her hand and leaned back on the chair as much as I could and said "oh god yes that's wonderful please put a little more weight into it". She tried but it was a little difficult at that angle so I got up out of the chair and lay down on the floor next to her desk and said "maybe if you applied a little weight with your foot it might be easier?". She looked down at me with a very bewildered look on her face and said "errrr... I'm not really supposed to do this I was just offering a little advice" I really didn't want to miss the opportunity of being stepped on by this big strong lady so I said "please it feels so good I haven't had this kind of relief before" and grasped the back of her calf which I then realised was HUGE, I mean ridiculously huge in fact I couldn't grasp it at all my hand was just flat against it and it was solid muscle! "my goodness!" I said "you have incredible calf muscles" she blushed a little and said "ok but I had better take my shoe off, I don't want to hurt you". WOW barefoot stomach stepping from a big strong woman like this!? I was in heaven and at that moment I was probably more turned on than ever before. I remember just realising I was a little wet downstairs when she placed one hand on her desk to steady herself and slipped her sandal off and raised her foot over my lower abdomen. Her sole was beautiful and I really wanted to feel it against my flesh so I lifted my top to expose my stomach "my goodness" she said as she looked down where she was about to step "you have some abs there sweetie maybe you can take a little more than I first thought" and with that sentence she placed her heel below my belly button and pressed ever so slightly. "How's that?" she said, it felt amazing but I wanted more so I said "yeah that's the spot but that's about the same amount of pressure as your hand, maybe you can put more weight into it?", she smiled at me soooo sexily and said "ok, maybe just this once" and then stepped maybe half of her weight onto me with her heel! This woman was BIG so just half her weight made me let out an "ahhhugh" sound as she really took me by surprise, I wasn't expecting her to put that much weight on me so quickly. I don't even think she realised the pressure she had just given me herself. "is that enough?" she said, I was trying to tense my abs as much as possible so I was a little red in face as I said "yes hold it there, maybe a little more?" with that she shifted her stance slightly and pressed even more weight into me! I was now bright red in the face as I watched her calf flex as she leaned into it, she looked down at me and said "is that too much?" I actually couldn't speak, I'd held my abs tight for too long and this was the most weight I'd ever had on me (she hadn't even lifted her other foot from the ground). I knew this woman could seriously hurt me if she wanted too, if she lifted her foot and applied her entire bodyweight I'm not sure if I would have coped and this had me really really turned on. I had to concede and mutter out "yesss.. thhankss", she lifted her foot and I was able to breath again. She held her hand out to help me up which I took as I actually needed it! I was a mixture of turned on and half conscious from being crushed. I thanked her and remember stumbling around quite a lot as I was all flustered and embarrassed, it must have been obvious to her that I was aroused. She said "imagine if I'd STOOD on you!?" I love the way she emphasised STOOD when she said it, I smiled and said "mmmmm yeah I can" and she smiled back :-) I wonder if I can do this again with her and maybe try the full weight next time? It might be difficult to instigate the conversation again but I'm thinking about trying.
Thanks for taking the time to read my story, it is not fictional it really happened and hopefully may happen again, I'll try to keep you posted if it does.
