I like thinking about my OCs and assigning them sex roles because as I’ve said before these guys are basically my sex toys and I find it fun to label them and contemplate their likes & dislikes.
For Matthew & Angel, I think Angel tops more frequently than Matthew but I think the reason for this is mainly because Matthew is a giant pervert who really gets off on a teenager fucking him. They do change it up sometimes because Angel wants to get fucked too on occasion but I think it works for them because Angel discovers (with Matthew of course) that he does prefer topping most of the time and also enjoys the weird sex talk that seems to make Matthew crazy. They don’t really have a D/s relationship it’s more a case of “these two people are extremely hedonistic but don’t particularly care to label it” so while they do like fucking around with different kinks and experimenting a whole lot they don’t ever get too deep into BDSM just because neither of them are really interested in Dom or sub stuff or sadomasochism. They really really just like sex and fucking and if that also incorporates feet or piss or cock cages or vibrators it’s normal for them.
For Jason & Heather it’s a case of Jason just doing whatever the fuck Heather tells him to. It’s really unhealthy. Jason basically feels like he owes it to Heather to do whatever Heather wants and that extends to sex. I think they top and bottom an equal amount but that’s solely according to Heather’s taste. I think they’re into some freak shit (besides the dadsonism of it all) and Jason probably learns to love what they have together because he realizes he’s stuck with this for life and might as well enjoy it. Probably further on in their relationship Heather will give Jason more leeway when it comes to sex but for the most part Heather calls the shots and doesn’t ask what Jason wants.
For Tzul & Alex they’re strict top Tzul and bottom Alex and I don’t really see that changing just due to the nature of their relationship, even at the end of their story Tzul still just begrudgingly likes Alex and I don’t see him ever wanting to bottom. The fact that Tzul is Alex’s torturer/rapist/captor makes it so Alex probably wouldn’t ever bring up the subject of topping during sex even if he wanted to (and to be honest he probably does like this man is straight he wants his dick in a hole). Alex grows to enjoy sex with Tzul but that’s more because of manipulation and conditioning and less to do with Alex actively wanting to sex that he’s hardwired to not enjoy. Everyone point and laugh at the straight man bottom.
