SONE-887 | So close! So close! So close! My girlfriend's cute little sister, Marin Mita, is so close that you can 100% kiss her!

[Can you resist being stared at by such a cute and cunning girl?] Today is the long-awaited date with my girlfriend. When I get to the meeting place, I'm surprised to see her younger sister there!? Apparently her name is Marin-chan, and we decide to go to their house. But Marin-chan seems to be acting strange. She's really close to me. Not just physically, but even her face. Face to face, almost 0cm. Almost zero distance to her lips. What's going on... She's too cute, I can't handle it. She's too cunning. Can I kiss her? Is it okay?! Smack!!! And my libido exploded.
