Translated DLsite desc: 『Demon Fist Yukine』by Binkan Argento A female agent who defeats lewd demons as a demon hunter. After successfully defeating an intermediate level demon, she is caught off guard by an elite/advanced demon that attacks her from behind while she is communicating with her operator. The staple food of these demons is human female energy, and the purity of that energy is increased through arousal. The demon injects the female agent with an aphrodisiac and begins to torment her nipples relentlessly. She struggles to endure the forced pleasure while her crotch gets wet. Remembering the humiliation she once had with a demon, she attempts to endure it at all costs, but the tentacle insertion into her nipples increases her pleasure level too far. She is nipple fucked while spewing her breast milk, and the tentacles continue to absorb her energy. The female agent is completely demolished by the tentacle’s finishing blow, and she is held captive as the demon continues to feed on her pleasure.
