"the serum"
scientists discover a formula which enhances female development (size and figure). it has to be ingested by a man, before it's transformed and ingested by the woman in his semen. only trouble is, take it makes him shrink.
"sirens are real"
witches dominate men, shrinking them as they replenish their powers and youth
a man fights with his wife, and is picked up in a bar by a woman who seems far out of his league
she seduces him, trapping and pleasuring him the whole weekend as he shrinks and she grows more beautiful and powerful
"shrinking fortune"
a wealthy man at a party approaches a ravishing beauty. she uses a form of seductive honesty -- flaunting his obvious interest in her body, while openly disclosing her interest in his money.
she makes him jump through hoops to get her in private, and when he finally does, she psychologically dominates him, getting him to worship her body as she pleases him.
he's incredibly smitten by her, and keeps trying to coax her into the sack.. but she resists, making him buy her increasingly expensive things (cars, jewlery, yacht). each time, after he complies, she dominates him, teasing and pleasuring him.
finally, she doesn't want any more gifts from him. he tries to escalate to giving her more gifts. She only wants one thing, "i want you to drink this. before you drink it, however, you should know. It will make you a tiny little man, who is forever mine to toy wish as I like." / he laughs, thinking this is already true, and drinks it. / She starts teasing and dominating him, pleasuring him, and after a few minutes, he realizes something is wrong. She's growing larger. He freaks out, but she calms him, assuring him that she's not growing larger. No, as she said, he's growing smaller. She sexually dominates him as she recaps their relationship, and how much she knows he loves worshipping her body. She flaunts it over him, letting him kiss and suckle against her even as he shrinks down to about a foot tall. / Then she picks him up, handling him like a toy as she psychologically forces him to get hard and climax against her multiple times in a row -- laughing at how he can't even stop himself from reacting to her.
When she finally finishes initially toying with him, she puts him naked into a birdcage, instructs him on what she expects from him if he wants to survive, and adds him to her 'collection'.
"hypnotic exposure therapy"
a man has trouble with his wife, because he's sex obsessed with her tits (always grabbing her tits)
an unusual clinic promises to cure people of phobias and obsessions through a unique type of drug and light stimulated hypnosis -- they have a very peculiar pricing structure (first session is free unless they cure you, later sessions are increasingly expensive) -- he is suppose to press a shock trigger when he experiences the obsession he'd like to cure
the hypnosis creates incredibly real experiences of the obsession (or phobia), so much that the MC wants more and more sessions (feigning he hasn't experienced his obsession yet)
however, the obsession starts to 'bleed' into his normal life.. and the hallucinations begin - soon everyone from his wife to the convenient store clerk looks like his ideal obsession
he goes to the clinic, confessing that he's halicunating.. they calmly explain that rarely the procedure can trigger an overflow reaction into normal life. they give him a mobile shock trigger, to allow his treatment outside the clinic -- coaching him that when he sees the halicunations, he should push the trigger.. even as the woman coaches him, she looks like his sexy obsession, yet he lies and says he doesn't see any halicunation at the moment
He tries to calm down, getting "used to" seeing every woman as a sexy busty object of his desire, and decides maybe it's not so bad.
His wife looks awesome. He complements her, and pushes them towards intimacy. She asks how he's doing, how the work at the clinic is going, and he says he's definitely feeling different. We get to see their 'split' perceptions of the situation, as she percieves semi-normal intimacy, while he percieves her smashing her tits into his face, and verbally teasing him about it.
