Yuuna-chan is a beautiful girl with a short haircut and beautiful breasts! She has a serious look on her face when she hears about a virgin's troubles, as if she thinks it's a big deal. She's a big sister-type, kind-hearted girl! She's given the title of sex practice, and after she's increased her sensitivity with some dry sex, she slips in and pistons hard! Her sensitive body keeps climaxing instantly, but she ignores him and pounds away! She keeps tapping away, saying "I can't take it anymore!"
