MIDA-240 Let me borrow her for just 10 seconds…! I let my best friend, who I had formed a virgin pact with, spend a brief moment with my girlfriend… and somehow they turned out to be unbelievably compatible, so lately my girlfriend has been acting strangely!! Sakura Minato

A close friendship built on a shared vow of staying single. But as time passed, I got a girlfriend too. When my secret was exposed, my best friend and I were on the verge of a falling-out. I couldn’t bear to lose my only friend…! To make up with him, I made a promise to let him be with her for just 10 seconds, and that was my mistake. The moment he entered her, her expression changed and she started gasping… “Ah… ahh…!” Wait, no way. She wasn’t actually enjoying this, right? I never imagined they’d be this compatible. After that, the two of them kept secretly meeting again and again. I never thought I’d end up losing both my best friend and my girlfriend at the same time…!
