Let Her Insert Herself For 10 Seconds...! When I Lend Her To My Best Friend, With Whom I Had Formed A "virgin Alliance", For A Moment... I Had No Idea That We Would Be So Compatible, But Something Has Been Wrong With Her Lately! Sakura Mizuto

My non-mate friend and I built a [Virginity Pact], but time passed and I got a girlfriend. When it was discovered, I faced a crisis with my best friend! I can't lose my only friend...! To get forgiveness, I let him insert into her with a promise of [just 10 seconds]—that was a mistake. The moment my friend's dick entered, her expression changed and she started moaning... 'Ahh... ngh!' Wait, no way? You didn't just cum, right? I never thought they'd be this compatible. After that, the two secretly keep hooking up. I'm going to lose both my best friend and my girlfriend...!
