Yui, a junior at National College, participated in the 1000 meter race. Her skin is fair and smooth, her hips and buttocks are high, her breasts are full, her body is tight and her skin is fair. Yui trains hard and her pussy is tight and comfortable. She's super flexible and can pound away in the girl-on-top position. Her libido is extraordinary, and she is so satisfied after one session that she will persist in her quest for orgasm! Even when she's sweating from an orgasm, she'll keep going until she reaches the end...
