Reiko Motomori, a mature woman with a penchant for taboo, finds herself alone with her son, his young cock tenting his pants. She can't help but reach out, stroking him through the fabric before pulling it down to reveal his hard, eager flesh. She takes him into her mouth, sucking and licking until he's panting. He returns the favor, his tongue exploring her mature pussy, lapping up her juices. They switch positions, Reiko on her hands and knees, her son pounding into her from behind. She moans, her pussy clenching around him as he fucks her harder, faster, until he can't hold back any longer, pulling out to shoot his load all over her ass.
