Today is the graduation ceremony for her step-son, who always washed his pants covered in semen! Stepmother Futaba Mio, who has loved her son since he was little, takes a bold step to take his virginity before he gets a girlfriend! She straddles her son's young, hard cock, which he is confused by, and inserts it raw and vigorously pounds it into him! Showing her son where it joins her, she praises him, saying, "It feels good... You're good at it," and then she accepts his sperm, which she always smells and gets aroused by, in her vagina! "You've grown up, Sho-chan," says the perverted, slutty stepmother, smiling with satisfaction! But one time just isn't enough, so she wants one more time♪
