She acts cold and indifferent when we meet, with zero friendliness—but whenever I call, she always shows up. Let me introduce my sex partner, Fumika-chan. When I asked her to wear sexy lingerie, she grumbled a little but obediently changed clothes anyway. The way she acts all tsundere yet ultimately follows my lead is incredibly cute. I wanted her to see herself in the mirror wearing that naughty lingerie, so I inserted my cock right in front of the mirror. She looked embarrassed, yet writhed in ecstasy at the lewd sight of herself being fucked—super erotic. When I pounded her tight pussy hard and deep, she completely switched into slut mode, moaning loudly as her pussy convulsed and clung to my cock. I came hard with a creampie. Still not satisfied, I attacked her pussy with a vibrator buzzing on her clit. I put an onahole on the tip of my cock and thrust it into her pussy. Even after blasting cum all over her belly, she kept going—this girl is seriously horny. I drizzled oil over her big ass and spanked her while thrusting, making her scream, "It's hitting deeper than before!" as she writhed and increased her hip speed. With a cocky tone, she spread her pussy wide, so I shot another load right inside. When she tried to casually get dressed and leave, I turned the vibrator up high, stimulating her pussy until she cried, "Too strong, stop!" while writhing in pleasure—her erotic switch clearly turned on. I shoved my cock in front of her face, and without hesitation, she took it in, sucking noisily with wet, slurping sounds. I fucked her bare pussy over her clothes again and again. Finally, I blasted thick cum straight into her mouth. I sent her off with a remote-controlled vibrator still inside, escorting her to the station. While she was climbing the escalator, I increased the intensity and got an angry glare—but it's obvious she actually loves this kind of play (laughs).
