Jun has gotten a serious boyfriend and decides to use me, a lowly office worker, as her sex practice dummy to completely win him over. She says to me in a mocking tone, "Sorry for making you come all this way. You always leave right on time, don't you? I've never seen you talk to anyone at work about anything other than your duties. You don't have any friends, so I figured you must be lonely. You don't have a girlfriend anyway, right? Probably just waste your time going to brothels." Though her words make me feel slightly embarrassed, I can't help but get secretly excited imagining why she chose me. Jun flaunts her incredible blowjob skills—not only gripping tightly and jerking me off roughly, but also slowly stroking and mixing in feather-light touches, accurately hitting all my sensitive spots. Her handjob technique is so skilled, it's as if she's a professional, driving me closer and closer to the edge. "It's been so long since I've seen a real cock—I got excited..." she says, then adds, "As a thank-you, I'll teach you how to touch a woman's body," allowing me to touch her. She's extremely sensitive, moaning and reacting intensely from even the slightest caress. Then she whispers, "Actually fucking you might be surprisingly good..." and takes my cock deep inside her. Despite me being just some guy who only knows paid escorts, she trembles uncontrollably, genuinely overwhelmed by pleasure the moment I enter her. Her cowgirl rhythm is incredibly erotic, and when I climax deep inside her, she gently forgives me. In the end, I can't help but feel she might actually prefer me over her real boyfriend.
