While their parents are away, a brother is treated like a toy by his step-sister. While he is relaxing in his room, his mischievous step-sister comes in and starts playing with his dick. The step-sister is curious about anything naughty, and with a bottomless sexual desire, she slurps on his fishy penis with her saliva, then slides it into her pussy without a condom. The step-sister is so naughty that she moves her hips obscenely while engaging in a deep French kiss, and intentionally makes him cum inside her, leaving the brother at a loss for words.
