"Do men also like their nipples played with?" Student council president Sumire goes to a love hotel after school to study sex with a perverted old man she met on social media. Seeing the old man moaning and feeling pleasure from his nipples, she becomes addicted to nipple play. "Does it feel good if I pinch it? Does it feel good if I bite it? It's dangerous if he licks it, right?" After playing with her nipples and getting her pussy fucked by his hard cock, her adolescent sexual rampage continues.
