I've told a few close frens bout this. 1st of which is openly into inflation of multiple kinds, most of all anything full body &/or belly related. While I myself am more into boob alone or the 3 B's (boobs, booty, belly) inflation in combination; I mentioned to all 3 of em that I'm also into inflation as well as that I have a soft spot for full body inflation. However, full body really depends on the artstyle to me [when I do find good art of it, it's pretty qto & maybe even incredible]. 1st fren wasn't suprised but she was so happy to hear it from me. Ironically, I like some pudge yet I'm not into that much fat [like super morbidly fat] really at all cuz of all the rolls & stuff that normally goes with it [naturally]. She however is lol. Full body inflation on the other hand usually results in a still soft but nice round shape with smoothness & that's what draws me more to that. Kinda like a blimp or water bed. Tho I do like some pudge & a grabbable/mostly smooth orb like tumby or somethin in between. Not into popping at all tho, I'm fine with it if it's like a cartoon & they just go back to normal but are dizzy for a little bit. Yet I just like big ladies that are huggable. Hence my love for hyper boob. Also vore, & a fair bit of preg [hyper as well of course].
2nd fren being into vore from the get-go as I am was very curious to know bout this & he actually got into boob, booty, & tummy inflation cuz of me. Sometimes he finds appeal in full body as well, but mostly only through liquids such as water or slime.
3rd fren was already into big round tummies as well as again vore but not so much full body inflation but he's ok with me being into it & seein' pics of it.
I've chatted with all 3 of em a little bit about these kinks & they all turned very well. I still send em art sauces I find & vice versa.
I did once have another fren [I'll call em Shyla] who was into it too who I told my kink about, yet I haven't seen em in years. Hoping you're okay out there, if somehow ya find this.
I've yet to tell em where it really all started, I do plan to however just cuz they've been very cool & are into most of these same kinks as me anyway including these [esp hyper boob]. Plus it's very rare that ya have gud frens ya can really dig deep into kinky chats with. I'd esp like to do that more with em when they're all free to.
Overall, I'd say I got pretty lucky on that front at least if not much else. It took me a fair bit to tell em cuz I was a lot more shy bout it around em. Otherwise, I'm very discreet about my kinks everywhere else, as anyone should be tbh. Besides hyper boobs & boob expansion/inflation, goth, robot girl, monster girl, "big" sister type size difference, etc, & maybe some pudge. I do still find a few of these kinks I have def weird as most kinks are but I don't feel bad bout liking em. Cartoon like flattening is kinda growing on me too.
