Fat people can have sex. Very fat people can have sex. It takes a lot of work, requires equipment and patience, but it can be done. It's not romantic, but generally the people willing to be that patient and use props have a bond that makes the experience less mechanical. Even if Chantal's potential beau was not a fetishist, seeing her as a wholly different sex object than what she prefers, he doesn't know her well enough or care enough about her yet to explore the very specific ways one can have sex with someone with her physique while also making it pleasurable for her. She will not leave such a coupling satisfied.
Worse, Chantal has not had sex in years. She is 100 pounds heavier than she was when she was last intimate with a man and has had major abdominal surgery that cut through her muscles and if she's done any physical rehab to strengthen her core she's kept it secret. She takes no hormones so she's not yet familiar with the physical changes that happen when a woman's body no longer produces estrogen or testosterone. When doing that Onlyfans video where she was kneeling on the bed, she could not maintain that position for long, swaying and losing her breath quickly. She's heavier, weaker, and wholly different hormonally than she was last time she engaged in sexual activity, and will be very surprised at how different things are now.
Chantal does not really understand the mentality of feeders or men who prefer monstrously fat women. Forgive me for engaging in generalizations, but as a group they are not nice people. Because a person as fat as Chantal often has little agency in terms of money, social status, emotional support and physical stamina, they are easier to control psychologically and as a result many of those who engage in this fetish don't really have to go the extra mile. The aren't bringing flowers before demanding the object of their affection drink a quart of whipping cream through a funnel. They aren't doing the fatty/hetero version of the reach around, giving their partner pleasure as they fuck a roll or poke around in a belly button.
Chantal received messages on OF that upset her, and we can only speculate what they were, but if she was unable to endure the requests of anonymous men on a site ostensibly devoted to women catering to the requests of anonymous men, what will she do when she realizes, beyond a shadow of a doubt, that this dude is only interested in groping her gut?
The process of being desired is important to her. She does not want to be seen as an aging SSBBW who takes what she can get. She does not want to be HungryFatChick. She wants to be seen as a plump goddess. She's going through a sort of ritual many women undertake when dating someone new, though it is seldom done so publicly. Sexy new lingerie, hair removal, skin masks, lotioning up her body - she clearly wants to be desired in the same way the vast majority of women are desired and engaging in pre-sex self-care both makes a woman feel more confident but it's also a sort of psychic armor wherein you narrow avenues of criticism. If you smell good, look good, feel good in your new lingerie, then you feel better and more confident.
Except men who like women her size often want them to stink. They want to find residue between rolls. They like finding pockets of unsightly hair, gunk in the belly button, crusty feet - go hang out on a site devoted to feeders and fat fetishists and see for yourselves. On the message boards, you see dudes talking about the specific stink they like to smell - mushroomy feet, cheesy folds, cumin-y armpits and thigh creases, onion-scented sweat. They don't give a shit about hair, makeup, or nice-smelling perfumes or lotions. They do like lacy lingerie because it often leaves patterns and imprints on the skin, but care little else about it.
What will happen to Chantal when she realizes that all the things she loathes about being fat is what a fetishist wants. She talks a good game with farts and shitting everywhere, and telling her unreal stories about her ho-days, but she's sexually naive and she's not well mentally or emotionally. The way she talks makes it seem like she would love a dude who doesn't need her to shower or wipe her ass well, but the first time she is treated like s stinking, unsightly lump whose sole purpose is to serve as a prop in someone else's fantasies, it will crush her.
Who knows, maybe this dude will caress her tummy while also showing care and concern for the owner of the tummy. Maybe he's an outlier in that corner of sexual preference. But it seems unlikely and between the degradation she already experiences physically and the mental degradation dealing with fetishists will cause her, don't be surprised if she crashes down into a pit of depression and misery that makes her previous neediness and depression seem mild in comparison.
This is why women need friends to tell them the truth, real friends and not enablers on chat, angry mods who feel spurned, and degenerate house gnomes who sulk in the cuck corner.
God, people think we are angry she is happy but really on my end it's that uneasy feeling that comes from knowing something really bad is about to happen to someone who is an asshole and the tension between not wanting to see it and also thinking it will be sort of fun in a car-wreck kind of way to watch.
