In truth, even though she really loves him, they've been fighting and she can't spend her birthday together... She asks a handsome actor to cuckold her instead and cum inside her to wish her a happy birthday! Mori Hina, who doesn't know anything, gets a luxury car drive, a helicopter night view, 100 roses, and a cum-hugging necklace. After pleasing her with a number of surprises, the raw sex they have is super cute and super erotic (there's even a surprise twist at the end, using Shinjuku's giant screen!!?).
