A shame-filled exhibitionism challenge: dressing an adult woman in a school uniform. Mina seemed to have enjoyed the previous uniform play a lot, so when I asked her to wear the sailor outfit again, she happily agreed. "Haa, you're such a troublesome person... This is the last time, okay?///" she said, pretending to resist while clearly delighted. In such a cooperative mood today, we went for a walk with Mina and the "jumping vibrator." Once we reached the apartment staircase, I inserted the vibrator and secretly turned it on. "Aan!?... Nn... Aa///" Fidgeting, Mina desperately tried to suppress her moans, not wanting anyone to see. So I cranked the vibration up to "strong," causing her to crouch down from the intense stimulation. "Wait... someone might come... Aaaah, no, stop///" I then took her to the shared rooftop space and continued the humiliation play. Mina climaxed repeatedly, struggling to stay quiet. "Aaaaah, no no no... this is bad, wait, wait///" Then—gushhh... she unexpectedly peed herself. Her skirt was completely soaked, so we hurried back to the room laughing. I had invited a friend over, who now joined us, throwing Mina into total confusion. "Huh? Wait, what are you doing? What are we doing, three of us? I don't get it w///" Now it was a threesome: Mina in her sailor uniform, my friend's cock, and me. Mina sucked his dick eagerly, then finally took it deep inside her pussy—sllluuurp!!! Overexcited by her first time with another man, she was so horny that my friend couldn't stop thrusting. Mina lost all control during the intense sex, and we ended up going for a second round. We jerked off both cocks together with oily, slippery hands, then launched into a full-on greasy threesome. In the end, we blasted her face with massive cumshot loads, thoroughly enjoying the insanely hot mating session.
