I'm just an ordinary college student, like any other person... The only thing that makes me different is that I live with my girlfriend, who is beautiful and has a great body, even though she is way out of my league. My girlfriend, Ichika, is very kind. But... there's something that's been bothering me lately. That is... she loves my nipples more than I love myself... my nipples are twitching whether I'm awake or asleep, regardless of my will... my nipples are living as Ichika's slaves...
