AGAV-182 Human futon. That unsatisfied kid and me, who got into the comforter, sometimes get NTR'd while sleeping. Muranaga.

―Human Blanket― This refers to a man who sneaks into a woman's blanket, wanting to secretly feel her scent and warmth at night. Just beyond a thin sheet of fabric lies the female body, unknowingly being invaded by the man's body as she sleeps. However, the human blanket is ultimately just a shadowy existence. The woman, unaware of him, used a female-only sex service and openly displayed her desires in front of the futon. I can't take it anymore. I want to touch her directly. It's time to remove the veil.
