Seiko C - Who Has Been Performing Since She Was Small, Rubs Up Against Adult Society (part 1)

Aika was originally a girl I met through a social networking service because she was having trouble paying her school fees. She is petite and has a childish face, but she has I-cup breasts, and her imbalance is very attractive. She is now my friend and I often call her up because she is quite dominant and has a strong need for approval.
