Aiko (23), someone I've known for a while and actually my friend's girlfriend. We were supposed to have dinner together today, just the three of us, but I got a message saying my friend might not make it due to work. It's annoying when someone can't just say outright whether they're coming or not. But this time, it turned out to be lucky. I changed the plan and moved things to a hotel room I'd booked, suggesting we just hang out and drink there instead. Of course, I informed my friend—he wouldn't mind, especially since I got a nice hotel on company expenses. I told him we'd all relax and have fun (half-joking, of course). The other half? Well, I definitely wanted to fuck her. I knew Aiko had big tits and was easy to pressure into sex. Since I had a great room and was planning to bring in a call girl or someone I'd picked up online after work, I'd brought a vibrator just in case—and now I put it to use. Though she was probably still thinking about her boyfriend, she was also pissed he'd flaked on her without a proper explanation. And more than anything, she was a horny girl who couldn't resist pleasure, especially someone as weak to advances as Aiko. She started clinging tightly to my cock, my friend's best friend. Once I was inside her pussy, she squeezed me hard—so damn tight and hot. Her reactions were filthy; she wrapped her arms and legs around me as I pounded her missionary, moaning "dai shuki hoorudo" and making the dirtiest moves. Part of me still wondered, "What if he contacts us…?" But judging by Aiko's actions, that thought had already vanished from her mind.
