Today is a special date with Mizuki. I came up with a unique plan and met her at our rendezvous spot, where I secretly attached a remote-controlled vibrator and a strapon to her. Mizuki is my proud girlfriend—big-titted, extremely horny, and irresistibly cute. Though initially hesitant, she agreed, letting me equip her right there on the street. Her reaction was even more exciting than I expected. As soon as I turned on the strapon's switch, her body trembled and she started squirming. She crouched down on the sidewalk, overwhelmed by pleasure, her face flushed with shame as if she didn't want anyone to see. To passersby, she probably looked suspicious, but that was exactly the thrill of this date. Repeatedly triggered by the switch, Mizuki collapsed onto the ground, her legs shaking uncontrollably. Her unbearable arousal radiated from her groin, and her ecstasy gradually surfaced on her face. Naturally sexy and adorable, Mizuki grew even more seductive as she struggled to endure the pleasure. Even when approached by strangers, I kept the device turned on. Eventually, she couldn't take it anymore and sat down right on the street. By now, she'd completely shifted from dinner mode to full-on horny mode. We moved to the staircase of a nearby building to avoid attention, continuing the strapon torture. Her entire body writhed and trembled until, unbelievably, she climaxed from the strapon alone. I switched the strapon from her groin to her nipples, teasing them with vibrations, making her moan helplessly. I mischievously caressed her overheated, lustful body as she, tormented by shame and pleasure, thrust her ass out and shuddered through orgasm after orgasm. I pulled her panties aside and relentlessly tormented her with the strapon. Her reactions? "No, no, stop!"—yet her hips buckled as she came over and over. I went down on her ultra-sensitive pussy, sucking and licking her fiercely, driving her into convulsions. Burning with desire, she moaned while touching the bulge in my pants. Faint voices of people nearby could be heard, but lost in pleasure, Mizuki willingly took my cock deep into her throat, performing intense deep throat. Since the strapon was still attached, she climaxed mid-blowjob, her whole body jerking violently. Suddenly, I said, "I'm going to fuck you now," to which she panicked, "Here? Impossible!"—but still, driven by desire, she thrust her ass back and accepted my cock in doggy style. Even while covering her mouth, moans escaped her lips, turning me on even more. Just sliding my cock in and out brought Mizuki to the brink, and she climaxed again almost instantly. Wanting more privacy, we moved to a quiet landing inside an apartment building. The moment we arrived, Mizuki suddenly became aggressive—kissing me passionately and sucking on my nipples. Unable to contain her excitement, she not only gave me a blowjob but boldly started titty-fucking too. She mounted me face-to-face, impaling herself on my cock, moaning uncontrollably as we fucked hard. We switched to cowgirl position, then reverse cowgirl, relentlessly pounding her. I fucked her hard from behind, spanking her ass with each thrust, making her entire body spasm in ecstasy. Finally, I unloaded a massive creampie deep inside her tight, quivering pussy. Flushed and breathless, I fully savored this shame-filled sex with my gorgeous girlfriend.
