HHKL-023 - Used as a practice dummy for my female classmate's condom training

A serious classmate asked me to help her practice putting on condoms without ruining the mood. Before I knew it, she was using me for practice, and when she tried to put it on with her mouth, she got so excited I finished right there. She didn't stop, though—she rode me, broke the condom, and we ended up having raw, unprotected sex with a full internal finish.
