A junior colleague secretly watches his senior's videos and discovers Kohinata-san, then surprises him by sending a message saying, "Senpai! I went to see Kohinata-san already lol." While his initiative is impressive, it's a bit overwhelming how he keeps booking the senior's favorite girls one after another. Still, his laid-back attitude of "Well, I'm gonna watch the videos anyway lol" shows real growth. Today, Kohinata appears in an unusual look—her usual short hair tied up in a single ponytail, making her look incredibly cute and instantly sparking the thought, "Whoa, this is exactly how I've always wanted to see her..." What's more, she's chosen the masturbation option, which comes as a shock. When the junior boldly says, "Please let me watch you masturbate!" she responds adorably, "It's embarrassing when you say it so seriously... shy laugh." He's grown so much that he even asks her directly, "Do you masturbate?" She shyly replies, "Eee~ it's embarrassing lol... I've done it a little before... lol," then sits on his chest while still in her panties and begins the masturbation service. Watching from this front-row VIP seat drives him wild with jealousy. Then finally, she takes off her panties, revealing her masturbating body right in front of him. Embarrassed, she lifts her skirt, touches her clit, and moans, "I'm starting to feel good..." As she inserts her fingers, wet squelching sounds fill the air—her voice and movements turning serious and intense. "I'm cumming... I'm gonna cum!" she cries out, her pussy dripping wet as she reaches a powerful, genuine orgasm. Watching from the best seat in the house, the junior's cock is already rock hard. After being generously coated with lotion and having his nipples teased with fingertips, he erupts in rapid spurts of cum. "Wow! It's still coming!" Kohinata exclaims as he shoots a massive load. "I'll be back again soon," he promises—his boldness truly remarkable. She's a slender beauty with B-cup small breasts, stunning legs, and a perfect ass. In the end, she gives him a handjob, vigorously stroking his glans with her skilled hand. While professional men's esthetic services are great, specialized handjob parlors featuring inexperienced amateur college girls (JDs) and office ladies (OLs) are highly recommended. These are much cheaper than regular adult services like delivery health (deriheru), health clubs, soaplands, hotel health, kaiun massage, or erotic massage, yet still guarantee a satisfying release. There are plenty of cute, beautiful girls available. Just like with other adult entertainment, depending on your negotiation skills, you might even meet outside the shop, have them wear your favorite cosplay, film gonzo-style sex, or watch them masturbate—anything is possible.
