Somewhere in the 430s was my biggest, all belly, medium tits, thick legs but a flat ass, very strange and though I love a huge belly, not my usual body type preference. She wasn't super in the the whole fetish side of her weight but was well aware of it and accepted it. I tried not to press too much cause it seemed like a sensitive topic and I was only looking to casually date at the time. Our first date we went to a restaurant and she ordered a burger, fries, some big pasta dish, and a desert, and ate all of it while we talked. I thought she was putting on a show since we had chatted a little about my preferences though I'm very firm about not pushing anything wg wise, but she said she just didn't get anything to eat that day and was just really hungry. I swear I could see her belly swell around the table as the night we on. When we eventually left she was wedged into the booth and I had to help her out, she was embarrassed but no one else was in the restaurant so it wasn't too bad.
She moaned the entire drive back to my place, complaining about how the food was so good but she was so full, which admittedly was pretty hot. We ended up watching a movie at my place instead of going to the theater like we planned because she was feeling "ill". We ended up ordering some snacks and I rubbed her distended belly, eventually moving up (cause I honestly couldn't reach lower because of her hugh belly) and we ended up having sex.
Honestly, it wasn't great. She was very belly heavy, which is my favorite body type, but she all but refuses to move. It was like fucking a dead fish. She didn't even move her hands much, it was just her spread eagle on the bed while I fucked her. Her belly was amazing and it was like that one pick from BWS with some guy fucking a giant woman with a massive belly but other than that, very unsatisfying. She also refused to be on top or do any other position than missionary. which is fine, but boring.
She's since lost a ton of weight, maybe down to 250 Id guess, but her face is still just as fat so she looks weird unfortunately.
My wife is around 360, way hotter, does every position in the book, super flexible and loves to eat during sex. She's looking to loose a little weight but has admitted she loves having let go dating me. She had dieted to around 160 before we met, gained a bit when we started dating to 200ish, and has ballooned up since we met.
