Step-son eats out his friend's stepmom (subtitled)

The step-son sneaks into his friend's house to eat out his stepmom, who is unaware of his true intentions. She sits on the couch, chatting casually, while he drops to his knees and begins to suckle her pussy. The subtitled hentai scene adds a layer of tension, as she tries to hide her moans from her friend in the other room. His tongue works her folds with skill, making her grip her thighs tightly to stay quiet. Her eyes roll back in pleasure as the secret act intensifies.
