[FB/Fu4F/Fu] We're catching up, it was supposed to be a one night stand...

A plot with the premise of two friends and/or exes catching up years after college or high school and with them getting to know each other again or catching up (and/or with some discussion of their respective queerness discussed), she hadn't seen him in years and so...one thing led to another and she ended up bedding him that night and had sex with him until 3 in the morning. Said sex was also where she found out that he wasn't born cis-male and thus possessed breasts and a vagina in addition to his penis.

The morning after? Their new relationship starting or restarting under new pretenses/contexts as a result of the experience together and/or because of the orientation play or queer elements as a result. Intentionally left vague for further ideas/progression but her queerness and naughtiness came out to play after that morning:

Partial semi-findom and pampering / she starts going to local sex shops or adult media vendor stores, she also began to order things online, obtained physical catalogues if not just to avoid suspicion for anything her growing lil perv heart desired, lingerie, toys, maybe even a strapon harness

She began to really appreciate his intersex-ness to the point of both becoming overly eager/loving of his slit, tits and cock and getting a futanari fetish/having her pre-existing futanari feitsh (if any) further strengthened. Clarification wise: she’s not fetishizing his genitalias or his sex but it tickles her brain and often turns her on that he’s straight up a real example of the thing she’d schlick to the point that she greatly widened her physical/digital collection of such and began eagerly using it as fap-material when she was all alone and thinking of him~
