[takaaki (Akiyoshi)] Maturbating to Self-stimulated Ovary Fertilisation by Stomach Punching.

A curvy loner with a beauty mark transforms her social media following into a personal sperm bank, sweet-talking strangers into donating bottle after bottle until she can pump the thick, reeking load straight into her womb through a tube. What begins as the ultimate solo session spirals into something far stranger — stuffed until her belly swells taut, she winds up her own fists and hammers her stomach, using the impacts to drive the seed deeper toward her ovaries. The pages alternate between her bliss-drunk, tongue-out expression and vivid cross-sections of her insides, where sperm finally swarm a fertile egg and the title's bizarre promise of self-stimulated fertilization comes true.
