This ia a character LoRA for Sanae Mayuzumi from Fukudahdah's (non-H) Manga Iinazuke Kyotei.
This a sort of dangerous character with gorilla strength, a flat chest, and a wish to get impregnated by the MC. If she gets you leglocked, it may be too late to escape fatherhood. Death by snu snu is also a possible fate.
The trigger is Sanae Mayuzumi.
Standard description would be 1girl, solo, black hair, black eyes, school uniform, socks, cardigan, long hair, mole under eye, skirt.
You may want to refrain from playing out your (her?) fantasies about impregnating or not impregnating her on this site, given how much it loathes flat-chested characters. I'm sure she's at least 18 years of age, though, and old enough to build a family, with her trying for marriage and conception in the story...
