A married woman trembling with shame and guilt, fulfilling her husband's cuckolding fantasy, contacts the organizer of a spouse-swapping club. The woman, 28-year-old E Misato, married for three years, gets aroused by NTR dramas and consents, knowing her husband strongly desires it. Overcome with guilt yet gripping her erect clit, she reacts sensitively to foreplay. Moaning with rolled-back eyes, she diligently sucks a thicker cock than her husband's, and winces in torment when penetrated. Thrusting from below sends her into eye-rolling orgasms, and she screams at climax. Three weeks later, she cheerfully wears a sailor uniform, sucking a cock while a toy remains inserted, crying out loudly with each intense piston stroke, repeatedly driven to successive peaks.
