That reminds me that OC/fursona howard can technically somewhat do this, but by fucking others both consensually or nonconsensually, and steal their sperm to impregnate others both consensually and nonconsensually.ProbablyAlive wrote: ↑Sun Aug 17, 2025 11:50 am I found a relatively weird fetish and I really like it.
So on e621 its called spermicidal_takeover Defined as:
When a character's cum (and future cum production) is "corrupted" such that it no longers passes their own genes. Usually used in tandem with breeding, domination, corruption, or cuckold kinks.
Example: horse sperm entering a panthers testicles, leading to him siring the horses children, rather than his own, when he returns to his wife.
Generally performed by way of cum exchange and either illustrated with a sperm cell collision cutaway, or insinuated by text. Unlike "regular" cum exchange, spermicidal takeover carries the additional implication that the effect is permanent. Note that testicle impregnation shares a lot of the same visual indicators, and the two can easily be confused.
► Show Spoiler :
I personally call it the succubus/incubus kink bc medieval succubi/incubi can ' steal ' your sperm for other uses lol.
Kinda funny how I am seeing a similar kink described now, and glad I ain't alone on liking that kink.
