[Oobayashi Mori] Kotoko wa Isshou Yokkyuu Fuman

An anxious housewife named Kotoko is blackmailed into a night of relentless, perverse encounters with a lecherous professor and his associates, her massive breasts and swollen nipples becoming focal points of intense stimulation and ahegao expressions. The story unfolds through panels of forced bondage, electric nipple torment, and raw sexual acts that push her beyond virginity into overwhelming pleasure, highlighted by frantic dialogue about her helplessness and the professor's dominance. After the tumult, she reflects on the exhaustion of parenting and resolves to reclaim her role as a devoted mother and daughter, ending with a hopeful promise to prepare curry.
