For the past three months, I've been receiving tutoring from Hikaru. She's a college student attending a prestigious university—elegant, mature, and always composed. Not only does she teach me patiently and kindly, but she also has a serious and disciplined approach to studying. However, being a teenager, I find it impossible to concentrate when she's near. Her body heat so close to mine, the subtle scent unique to adult women, and the occasional glimpse of her cleavage keep eroding my motivation to study.
