When I treated my convenient sex friend lightly... I got seduced by her more erotic, bold, and mischievous best friend, fell into depravity, and betrayed my girlfriend with her best friend Tsubomi Mochizuki
I realized my girlfriend was cheating, and it hit me hard. Ever since she joined a university club, her attitude changed noticeably. She used to be so eager, but lately she's avoided sex with me. When I confronted her, she left for a club retreat. Right after, her best friend, Tsubomi, came over to my place. She claimed she lost the key to her bike and needed to come in. I couldn't help but stare at her panties peeking out beneath her mini skirt, though I kept telling myself not to notice. Tsubomi knew about my girlfriend's affair and actually encouraged me to move on, suggesting I find comfort elsewhere. We started kissing, spending intimate time alone in my room. I whispered in my heart—I still love her. But given this lucky break... if she's cheating, maybe I can too, just this once. I gave in and had an affair with Tsubomi. I knew it was wrong, yet I pretended innocence while doing filthy things. Her kisses and blowjob were insanely more erotic than anything with my girlfriend. Her body was extremely sensitive, incredibly slutty. After just one time, I was completely hooked—what a pathetic, pussy-whipped man I've become.
