Subaru, a new submissive, finds himself in the skilled hands of Mistress Okawa, a renowned Japanese dominatrix. She begins by lubing up his tight asshole with her spit, then eases in a thick, black dildo, thrusting it in and out, making Subaru squirm. She replaces the dildo with her strapon, pegging him relentlessly, his cries echoing in the dungeon. Okawa then fists Subaru's ass, her whole hand disappearing inside, stretching him wide. The scene is intense, yet Subaru takes it like a champ, his ass dripping with lube and sweat.
