A married woman experiences forbidden Polynesian sex with her husband's stepson, slowly deepening her intercourse over five days, savoring the ultimate climax. From the sixth day after the final day, she continues her frenzied, gushing pleasure with intense thrusting. (Tenma Yui, DVMM-348)

The father was away on a business trip overseas for a week. The university student's son, using a school project as an excuse, asked his stepmother to help him with Polynesian sex. This was different from ordinary sex focused on physical intercourse; it emphasized spiritual connection, aiming to deepen their intimacy over five days. Still unaccustomed to the thought of "if their relationship improves...", the stepmother accepted her husband and stepson's request. On the fifth day, when their sensitivity reached its peak, the long-awaited penetration caused her mind to go blank, resulting in continuous orgasms! The stepmother and son, crossing boundaries, secretly engaged in unprotected incestuous sex behind the husband's back, reaching an overflowing level of ecstasy!
