DVAJ-630 一名女子田径队队员被塞进1厘米高的“空气椅”中，臀肉晃动不已；在下半身强化训练营中，她的阴道遭到贯穿；随后在“活塞式女上位”中被猛烈抽插，持续了2晚、3天和10小时……

Erika, a member of the track team, is told that she is on the verge of participating in the tournament, so she applies to participate in an intensive training camp. However, when they go to the training camp, only Erik and the coach are there. Taking advantage of the fact that no other club members are around, the coach touches Erika’s body lewdly while she is doing the air chair. Anticipating that Erika would not be able to resist, the coach pressed the tip of Erika’s glans against the entrance of her vagina in order to make her endure the air chair… Erika struggled desperately to keep from lowering her hips, but eventually her physical strength reached its limit. The cock is gradually inserted one centimeter and two centimeters into her.
