Squeak...squeak... As I diligently applied the lube to the onahole, I felt the interior start to move slightly. ‘Did the inside just move? Or is it my imagination? It feels a bit warm inside too.’ Though it felt strange, I just thought, ‘Well, it’s expensive, so it must have some features,’ and didn’t think much of it. After all, it was my first time using such a large onahole. After making sure the lube was well spread inside, I positioned and inserted myself. It was slightly warmer than human body temperature and felt squishy and tight, making me exclaim in admiration. It felt better than any onahole I had ever used. About 1/3 of the way in, the tight interior made it difficult to go any further. “Is it because it’s my first time? I can’t get it in any further. I need more gel.” As I pulled out, it made a noise like uncorking a champagne bottle. Perhaps it was too much for the onahole since it was new, but the entrance wouldn’t completely close. I squeezed more lube directly into the opening and tried again. This time, it slid in easily, making me moan automatically. It felt as if the pussy was alive, sucking me in, and each ridge inside stroked me in such a way that I could climax instantly if I wasn’t careful. I was shocked that the advertisement wasn’t lying. I decided I’d have to leave a five-star review later as I continued thrusting. Squeak, squeak... Erotic sounds filled the room, and it wasn’t long before the intense tightening and suction brought me close to climax. I couldn’t hold back and climaxed immediately; simultaneously, the interior tightened and began to spasm with me. The pleasure was unlike anything I’d experienced with any previous onahole; I seemed to eject more semen than usual. “This purchase was really worth it. I didn’t know such things existed.” Despite having just finished, my erection was still going, so I flipped it on its stomach to a doggy style position. I started vigorously thrusting, admiring the rippling ass and twitching anus. As I pushed forward, the narrow interior stretched around my large glans, and when I pulled back, it tightened as if begging me not to leave. Compared to the small onahole I usually shook by hand, using the full-body onahole required more energy. After about 10 minutes of relentless movement, I climaxed again. It felt as if a succubus had drained my energy; my body was completely exhausted. After enjoying the long afterglow, I pulled out and drank some water to rest. As my strength returned, I carried the onahole to the bathroom to wash it. Given its size, it couldn’t be washed in the sink, so I had to use the shower. Ssshhh... I turned the handle, waiting until warm water flowed out. Once the temperature was right, I held the onahole under the stream. The wide spray allowed me to wash around the opening all at once. The moment water touched the clitoris, I felt something twitch. But I brushed off the thought, reaching inside to scrape out the semen and lube. Though I hadn’t noticed while just inserting myself, feeling around with my fingers made me aware of the detailed internal structure. There were odd bumps on the top, and the pussy walls were either wavy or had lots of ridges. “Wow, they really paid attention to the internal details. I need to clean this and write a review right away.” After thoroughly cleaning and drying it, I logged onto the site where I had made the purchase. And then a message popped up. [This page cannot be displayed.] What? The page disappeared in just one day? It wasn’t sold out but just gone, had I been scammed? Various thoughts crossed my mind, but it didn’t matter much anymore. By my standards, it was a pretty good onahole, so I decided not to worry about it and started working on my lab report which was due the next day. === The next day A mandatory lab class at the engineering college. I couldn’t graduate without it, but it was a dreadful subject that took up to three hours for just one credit and required weekly preliminary and result reports. Going to school to perform the experiments was irritating, but there was a silver lining. Shin Ah-young, rumored to be the prettiest girl at our school, was in the same lab section. Being able to see her for three hours was a relief from the tedious experiment. No matter how tough the experiment, just seeing her face eased my fatigue. As I arrived and sat down to check the equipment, Shin Ah-young entered. She always had a bright, pretty smile, but today her expression seemed gloomy and under the weather. Rubbing her lower abdomen, it seemed like she might have eaten something bad or it was just one of those days. ‘I should be careful when she’s like this. Better not to hover around.’ As her gloomy expression drew attention, our classmates started to inquire. “Ah-young, are you feeling okay today? You look a bit down.” “What’s wrong? Are you sick?” “Ah... no, I’m fine... it’s nothing.” She tried to smile, but her expression clearly showed she wasn’t okay. Her beauty still lit up the lab; large breasts that one hand couldn’t cover, a slim waist. And her jeans seemed ready to burst from her large hips and tightly packed legs. She truly deserved the title of having a perfect figure. And not just that. Her flowing black hair, large, dark eyes, long eyelashes, a high nose bridge, and lips that were small but plump. Her body and face together created tremendous synergy. I felt a stir below but desperately hid it, knowing it would be social suicide to show it. Stealing glances at Shin Ah-young’s backside, the teaching assistant came in and the experiment started. “Today’s experiment involves ~~~, measuring with ~~~, and doing ~~~. Let’s get started.” As the experiment went on, I noticed Shin Ah-young moving in and out of the lab more frequently than usual, reinforcing my suspicion that it was indeed her time of the month. “Great work today!” After a long session, I started packing my bag to leave. As I was about to head out, I heard my classmates talking to Shin Ah-young. “Hey Ah-young, want to grab some lunch with us later? There’s a new place nearby that’s really good.” “Sorry, I have something to do today... Maybe next time.” “Alright, see you next time then. Bye!” Since I wasn’t too interested, I decided to head straight back to my dorm. My mind was already filled with thoughts of using the onahole while fantasizing about Shin Ah-young’s body. Ding ding ding Once in my room, I threw my bag aside and immediately went for the onahole. I laid it on the bed and started to vigorously fondle its firm breasts. ‘I wonder if Shin Ah-young’s breasts are about this size? They seemed really big and soft. Would her nipples be this pink too?’ Curiosity got the better of me, and I climbed on top, positioning my cock between the onahole’s breasts. Although mine was large, it was completely engulfed by the G-cup breasts. I sprayed some lube over my cock and began rubbing it between the breasts, thoroughly covering every corner. As I rubbed, a new sensation overwhelmed me due to the lube. ‘Oh... so this is how it feels... It’s actually quite nice.’ While engrossed in the act, I felt something with my palms. Pausing, I saw that both nipples on the onahole were erect. The nipples were as firm as the breasts themselves. It was irresistible. I grabbed them between my thumb and index finger and began to play with them. After about five minutes as the sensation of climax began to build, I sped up my movements and ended up ejaculating between the cleavage. Blurt... Blurrblurt... Leaving a red mark from my palm on the now flushed breasts, I looked downward. Unlike yesterday, the clitoris had peeked out of its hood, and the entrance appeared somewhat moist. Though the oddity was greater than the day before, the erotic appearance made me dismiss it. ‘Ah, who cares? If it turns me on, that’s enough. Just keep going.’ I grabbed the lube and squirted it onto the clitoris. Watching the fluid flow into the pussy, the inside felt already sticky. I positioned myself and thrust all the way in one go. Then I felt something at the front end of my cock. ‘There’s something at the end... is that supposed to be the cervix? They even replicated that?’ Curious, I tapped the cervix with my glans, and the inside tightened and spasmed. Whether it was squeezing to draw in my semen or blocking me because that wasn’t a place to enter, I wasn’t sure. “Does it have a vibration feature too? It keeps tightening and trembling.” After a mindless session of thrusting and climaxing once, twice... I lost track of time. Eventually, I felt as if my testicles were completely drained and pulled out. Looking down, I saw the sheets were soaked, and a white, frothy fluid continuously oozed from the pussy. “Did I ejaculate this much? I need to wash and do laundry right away.” Cradling the onahole to my side, I reached the bathroom to clean it. Perhaps due to using it too vigorously, the onahole looked deflated. “Maybe I should have been gentler with it...” I washed off the dried semen from the breasts and the fluids that had leaked from the pussy with warm water. This time, I carefully wiped it down with a dry towel, hoping it would last longer. Hoping it would last, I stored it in a well-ventilated place and went about my other tasks.
