Ayaka, a married woman who grew unsatisfied with her husband's cock alone, finds her curiosity drawn toward anal pleasure. Seeking new thrills, she dives into an anal threesome, receiving simultaneous stimulation in both her ass and pussy, engulfed in intense sensations far beyond anything she's ever known. The feeling of penetration in her anus awakens new erogenous zones throughout her body, making her roll her eyes back as she squirts uncontrollably, screaming in ecstasy. No longer fulfilled by ordinary sex, her dependence on anal stimulation deepens—her body transformed completely, unable to return to how it once was.
