Slender beauty Nanako Asahina takes on her first cowgirl time trial! It's a simple game: if she can make a guy cum in cowgirl position within 5 minutes of insertion, she's a big success, but if she fails, she has to play a penalty. Nanako carefully gives him a blowjob, as she isn't measured before insertion. Nanako says she's good at cowgirl position. Will she be able to succeed?! You'll have to watch to find out!
