Her boyfriend was a serious, lanky guy with glasses, majoring in science—the kind of guy whose personality was defined by his earnestness. But his cock was just as serious, a rigid, by-the-book type that would instantly lose its vigor the moment its rhythm was disrupted. Miki loved sex and longed for wilder, more varied, depraved experiences. Yet, afraid of making his cock go limp, she never had the courage to take risks. That's why he kept cheating. Though she appeared demure, in reality, she had a strong sex drive and couldn't stop thinking about cocks. A true cock-obsessed girl who lived for blowjobs, she was absolutely thrilled by the sight of a man losing himself in pleasure from her mouth—a passionate, cock-loving, licking slut. Even light rubbing over her panties got her slightly aroused. Instant handjob? No problem. Today, she was approached again, hesitated at first, but decided to take the plunge when she noticed the guy seemed well-endowed. Miki went all out with her blowjob, completely exhilarated. Just the act of sucking made her pussy wet and slippery. She'd always wanted to focus purely on blowjobs, but since most guys insisted on intercourse, she went ahead and let him fuck her too, just to be safe.
