Everyone in the class knows that something has happened between yutong (aka tongtong) and zhangqiao (aka qiaoqiao to yutong).
And this is what happened between yutong and zhangqiao during the KI class today. I was early for the lesson today and zhangqiao was already in the class when I reached there. Zhangqiao, the hardcore philo KI kia, is already prepared to have an enjoyable KI session.
Look at how happy zhangqiao is before the lesson.

And here comes zhu yutong entering the classroom. At once he saw his dearest beloved qiaoqiao. Lust overcame his sanity and turned him into a lecherous monster.
There he is, extending his grips of vice all over qiaoqiao. Poor qiaoqiao is struggling using his utmost strength to resist the monstrosity.
Despite qiaoqiao's resistance, yutong still ultimately managed to overwhelm him. Here is qaoqiao, piteously subdued under the onslaught of yutong. (please do notice that sex is beside them. in fact, sex has been lurking around them, eyeing for a perfect opportunity to come between them, which is soon to come.)
Allah bless qiaoqiao that he'll not be too traumatised by this incident.
This is what happened shortly. I've pixelated the head part coz it's R21 (live yaoi leh). Anyway there is more to come between them. This is just the beginning. (rmb i told you all about sex lurking around?)

After this horrifying incident, I tried to take a photo of yutong. Yutong, whose insanity has finally subsided, realised that what he had done was very very very wrong. Covering his face in shame and guilt, he has decided not to let me take the shot.

Anyway, sex's grin suggested to me that he's satisfied after witnessing (or rather, participating in) the incident.
