I made a LoRA for "Small Dom Big Sub" recently and figured I should do the inverse as well, so here you go.

Trigger: big dom small sub, size difference

Quick prompts in case you just want to try the LoRA out:

Prompt 1: 1boy, 1girl, hetero, big dom small sub, size difference, sex from behind, medium breasts, indoors, bed, long hair

Prompt 2: 2girls, futa with futa, prone bone, big dom small sub, large breasts, size difference, medium breasts, indoors, bed, long hair, blonde hair, brown hair

Prompt 3 (blowjobs are by far the least consistent part of this LoRA, keep that in mind): 2girls, futa with futa, big dom small sub, size difference, (fellatio), sitting, large breasts, medium breasts, testicles, long hair, couch
