Made by 競泳水着の空 (TENT), directed by TENT

Swimsuit club captain Ema Maeda is made to stay after practice. She is forced to wear goggles between her legs and is subjected to obscene acts by the coach in the name of instruction. She is panting and screaming from the pleasure while being unable to move. Dirty minded instructor is free to do whatever he want. It is a full video, no cuts at all for the upload here because it was very well filmed by TENT (no mosaic).
