(Please see my other posts first; before you read further understand that I am aroace, not hypersexual to my own knowledge, and that I have only went through the normal amount of asian strictness during my upbringing, so please don't worry about my wellbeing from this post. With that out of the way-)
I have a fetish-like idea turned into a loose idea for artistic nudity narrated or depicted from an outsider view (ie perspective of an alien). >What if one or both of your arms worked like genitals?< , where the genitals that are either on your (fore)arm or are the entire (fore)arm can be fertile or infertile.
But I'm thinking of what would happen if a character had male- and female- behaving genitals for forearms that are infertile but otherwise functional, and there were still functional hands and opposable thumbs on the forearms-cum-genitals (pun intended).
Say the left hand functioned like the human male reproductive system and had a foreskin covering the hand (which is entirely made of the same tissue as the glans penis) as a sort of glove to leave some or little excess foreskin ending at the palm and could unsheath to the wrist area, and the opening (meatus) is on the palm where semen or/and urine exit from, while the right hand functioned like the human female reproductive system also with an opening, the uvula with a urinary meatus and vaginal opening leading to the interior genitalia.
The character could have gotten this through a dubious surgery, a curse from a witch, a scifi tool malfunctioning, anything really could be an origin story for the unimagined/able arm modifications. The forearms are probably boneless, strechy and flexible, which allows them to insert the left arm into the right arm if they feel frisky and want to pleasure themselves, though it depends on what desires the character has. They can also use these arms for intercourse with typical male and maybe female genitalia.
A story involving such a character could explore how they go about using their arms in everyday life, how they explore their new forearms in intercourse if they do decide to do so, whether they try to "fix" or "undo" the modification, and so on, being a sort of slice-of-life depiction of the character.
I would draw something to illustrate what I'm thinking of but my art skills aren't good enough. The character could have male/female/both/neither/other genitalia on their crotch, does not have to be human, and could be a real or fictional species with some creativity.
If you think this idea is good and are inspired to use it in some way, reblog this post or smth idc, credit is optional since someone else could have / has already thought through something similar, in which case **feel free to inform me about it**. I might try to delete this post on artistic nudity if it gets bad publicity or if this turns out to be a temporary hyperfixation.
It's not tagged as mature as I have decided that my interpretation of this is too far removed from most genitalia depiction, it's about halfway in abstraction from human genitalia to plant/fungi/microcellular/etc genitalia and my idea can definitely be taken to that extreme (guess that's another idea, arms with plant-like reproduction parts)
blep idk how tags work but theres only text here guys(gender neutral) sorry, if this abstruse and potentially suggestive stuff is actually interesting to you there's probably nothing more to find than this post (°~°)
