KTDS-649 Flat-Chested Creampie 2 Sara Kotone

Sara-chan, a small and underdeveloped girl, trains every day with her older brother in order to become an adult woman. To practice her kissing, she stretches hard to kiss her brother and has her small tits caressed gently to enlarge them. She is also a pure sister Sara-chan who asks her to inject her brother's sperm into her pussy that does not grow hair so that she can become an adult woman as soon as possible. Big brother and her secret training are repeated until her little wish comes true!
