START-550 — A Careful Life Started With Rui, Whom I Just Started Dating. A Sex Life Where I'm At The Mercy Of My Insatiable Girlfriend, Sometimes Slow, Sometimes Passionate. Ichinomiya Rui

Rui is a colleague at work, and we're in the same department, so we started talking casually. I confessed my feelings to her on impulse at a company party, and to my surprise, she said yes. I'd never had a proper relationship before, and having such a beautiful woman as my girlfriend and living together feels like a dream. Plus, on weekends we just stay home and have sex all the time... I'm living a life that feels somewhat unreal.
