For me, who has few friends, Valentine's chocolate has always been just one piece—from my mother. I've grown used to being alone, carrying that loneliness every year. But one day, after school, I visited my friend's house like usual. I rang the doorbell, unlocked the door, and stepped inside—only to encounter something completely unexpected. My friend was suddenly replaced by a girl. She was exactly the type I'd never even be allowed to interact with normally—short skirt, long socks, slender legs... Her name was Himari. She said, "Wait in the living room until my little brother comes home," inviting me inside. But now, I'm in the most difficult situation of my life. Himari won't go to her room! She's standing right in front of me, talking to me! And I can see her panties!!! Shit, shit, shit, shit... I can't stop getting hard!!! Please come home soon, my friend! Himari, whatever you do, don't notice my erection!!!
