Aiko (23) from Shinjuku Koyuen Women appears in this video. Unlike previous girls we've featured, she's not just someone we picked up—she's actually my friend's girlfriend, and also a friend of mine. We had planned a dinner date with three of us meeting up today, but her boyfriend might not make it due to work, leaving her feeling a bit uneasy. However, that turned out to be lucky timing. Since I had already booked a hotel room with company funds, I suggested we change plans and just relax, drink, and enjoy ourselves in the room. Of course, I made sure to inform her boyfriend about the change. I managed to get a high-end hotel on the company budget, so I figured we could all unwind and have a good time (half of me thought that, anyway). The other half? Well, obviously I wanted to fuck her. Aiko has big tits and I knew she was easy to seduce. Originally, after work, I planned to bring in a delivery health girl or someone I'd picked up via social media, but instead I ended up using that vibrator on Aiko. Although she was still thinking about her boyfriend, she was also frustrated about being let down yet again. More importantly, she's a total slut who can't resist pleasure and gives in easily to pressure. She started clinging to my cock like a desperate woman. When I entered her pussy, she squeezed me incredibly tight—so damn good! Her reactions were super erotic! While I was pounding her in missionary, she wrapped both arms and legs around me, moaning "dai shuki ho-ru-do." Part of me was still thinking, "What if her boyfriend contacts her?" but clearly Aiko didn't care at all. Man, Shinjuku Koyuen is the best.
