Kanchigai kara Tsukiau Koto ni natta Jimi na Joshi ga Jitsuwa Mechakucha Dosukebe Onna datta

The school festival is coming up soon. I needed to shop for my club's exhibit, so I asked a quiet, unassuming underclassman to come along—only for her to mistake it for a confession of love. She’s all giddy about our "first relationship," but honestly, she isn't really my type. Hoping she’d dump me right away, I threw out a wild line: "If we're dating, that means sex first, right?" But to my surprise, this quiet girl started teasing me by riding me.. Wait, what?! Didn't she say earlier she wanted a date where we could act like a lovey-dovey couple in town?! I thought she was just a quiet, shy girl, but she’s got this incredibly voluptuous, sexy body and is grinding against me so intensely. On top of that, she gives me this sultry, erotic smile and says, "You don't have to hold back.."—there's no way I *could* hold back after that! "Quiet girl"? Not a chance! She’s cute, incredibly sexy—she’s the best girlfriend ever!!
