Mizuki Amane is currently living together with her boyfriend, and the couple is rumored to be deeply in love. Today, returning home from a fall festival, they're relaxing in their yukata when her unusually flirtatious behavior starts making his heart race. Her passion quickly builds, and their loving session begins. Starting with intense kissing, she enthusiastically gives him a handjob and blowjob. Then, climbing on top, she rides him in cowgirl position, climaxing repeatedly—driving him to finally creampie her.
