I operate around Shinjuku, and after hooking up with a nurse girl at a club and spending an intense time together in a love hotel, she suddenly messaged me via LINE past 1 a.m. the next day: "Hey, let's hang out again sometime." That weekend, we met up in Shinjuku after her shift. This time, she came over to my place. Relaxing and playful, I became curious about her usual masturbation habits and asked her to show me. Watching her was insanely arousing. While we were chilling, my junior unexpectedly dropped by. At first she was a bit cautious, but after the three of us started fooling around together, she began to enjoy it and eventually didn't care anymore. Truth is, I had secretly invited him over. Even though she acted shy in front of my junior, she deliberately started getting affectionate with me. The mix of embarrassment from being watched and the thrill of this first-time experience slowly turned her on. Facing this H-cup beauty, my junior's cock quickly became rock hard. When he asked, "Wanna do 3P?", her reply was "I don't know…"—but that hesitation clearly meant she actually wanted to. She climaxed repeatedly with both my cock and my junior's. Drenched in bodily fluids, her entire body became soaked and sticky. It felt like I’d fallen into another world from which there was no escape.
