A classmate with small breasts came into the classroom in a hurry! She must have been in a hurry, because she was not wearing a bra, which made me very excited! I couldn't help but flick her nipples with my fingers, teasing her, but even though she was angry, her breathing gradually became irregular...huh? Is she feeling it? In revenge, she flicked my hard cock, and we both got really turned on! We ended up having raw creampie sex in the classroom!
