I'm a solo jerk off champion, and today, I've got my girlfriend's panties to keep me company. I inhale her sweet scent, my dick already rock hard. I grip my shaft, pumping it slowly, building up the friction. My balls tighten as I near my peak. I groan, cum shooting out, coating her panties, claiming them as my territory. I pant, pleased with my performance, ready to clean up and start my day.
