The first twink, his bladder full, decides to add a twist to his solo session. He stands, aiming his cock at the toilet, his body shuddering as he lets go, the yellow liquid arcing into the bowl. The second boy, hearing the sound, pauses his self-fucking, intrigued. He stands, his cock still hard, and walks over, watching as the first boy finishes pissing. He smirks, his mind made up. He'll join in next time, adding his own stream to the mix, their piss mingling in the bowl, their solo sessions becoming something more.
