A genius beauty with a IQ over 60, Mayu-san goes on an exposed date. After meeting for 5 minutes, she immediately gives a blowjob in a nearby toilet. She walks around the city with semen in her mouth, swallowing it discreetly on the train. Until sunset, she enjoys giving blowjobs in various places and swallowing in public. At night, she has sex while watching fireworks in a hotel. It was a fun day.
