Yumi has recently become obsessed with BBQs, and when Kosuke, her friend's son, came over, she invited him to join her for a barbecue. However, Kosuke kept staring intently at Yumi's voluptuous body. Noticing his gaze, Yumi gave in to a mischievous impulse and seduced him. He then unleashed his insatiable stamina, repeatedly thrusting into her mature body and cumming over and over again. With his endless energy, Kosuke continued fucking her relentlessly, pushing Yumi's body closer and closer to its limit until she began screaming in overwhelming sensation.
