[Otonano Omochiya (Hirokawa)] Otonano Omochiya Vol. 15

A bashful futanari younger sister in a cow-print bikini and bell collar invites her big brother to share a bath while their other sister is away, teasing, "Since it's just the two of us, want to take a bath together?" Her plan to seduce him unravels when both siblings become visibly aroused and nervous, her thick cock straining hard against the striped towel as she catches him staring at her eyes. With breathless anticipation and trembling vulnerability, the scene promises a forbidden, deflowering encounter steeped in sibling betrayal and raw, aching tension.
