許久沒見到教練，身材愈發精壯，連出席的助手也驚嘆：「這手感也太好了！」

After all this time without meeting, the trainer has gotten even buffer and leaner. Even my assistant gasped: “Touching him feels amazing!”

為了給教練新的訓練，調教前我只問他：「今天我們專練『插入』，你可以嗎？」教練二話不說地答應，只是他沒料到要插的位置不同。

In order to give the trainer some new training, I asked beforehand: “Will you be okay with it if we focus on ‘inserting’ today?” The trainer accepted on the instant, not knowing that the insertion point was different.

距離教練上次的尿道調教，已經過一整年，這次的難度當然也上升一個檔次。隨著金屬棒插入，在近15公分深處來回摩擦的酥麻觸感，都可以透過教練深沉的呻吟聲感受到。透過鏡頭，來一起屏息感受尿道調教的樂趣吧！

It has been one full year since the last urethra training, so it would naturally go up a notch this time. With the metal rod inserting the trainer’s cock, rubbing up and down 15 cm deep inside, we can feel that sensation through the trainer’s deep moaning. Through the camera, let’s all feel the joy of urethra training!
