Riko and I have been in love for a while. Every Friday night, Riko, her best friend Moe, and I gather at our house and have a party together. Today, Riko had to rush back to her hometown because her cat was sick, so only Moe and I continued the party as usual. Due to not paying attention to the time, Moe missed the last train and had to stay here with me. Suddenly, she began to pay attention to my chest and started touching it. From the moment Moe touched my nipple, things got crazy between us. She kept fondling, touching, and teasing my nipples. The sensual pleasure that I had never experienced before that she brought made it impossible for me to resist. We went wild, our nipples touching each other, exchanging passionate kisses. And in the three days my girlfriend was away, we kept having sex with each other, to the point where I didn't even know how many times I had ejaculated...
