Suburban setting, where Eli here starts to crush on new neighbour B who's just moved in next to him. It starts out as a watching-from-afar thing plus some polite interaction, where Eli just sort of sees him mow the lawn sometimes, or swim in his pool, etc., and then eventually gives flirting a try only to surprisingly succeed.
Either B was worn down after Eli started flirting and they give this proper relationship a shot, or B was well-aware that Eli was crushing and has some serious kinks to put into use, and Eli is brought into a completely new world (dubcon, whether it turns into full consent or not, is fine with me; blackmail and optional Stockholm syndrome qualities are also fine if you want to go a darker route).
I'm open to adding A/B/O dynamics, supernatural elements, and others. Age gaps (no limit, so really, as old as you want) are a bonus, as well as the sneaking around to keep the neighbours from noticing and gossiping, but my guy'll be somewhere around 18-21. Incest is OK too, and we can change it up so instead of neighbours it's a) an estranged father; b) brother; c) relative coming to stay. Or, if the father isn't estranged, maybe Eli's just come home for summer vacation.
I'm open to all kinks except snuff, and any and all PBs work. Some favourite kinks (but not at all required for the line) are feminisation, barebacking, overstimulation, anal virginity/training, and praise. I can have Eli top or bottom too, but would prefer minimal switching around during the line itself.
