In terms of sex between two men, the top was the one who gave, and the bottom was the one who received.
Probably that's why Yan Renzhong decided to "give" it to Shen Jingwei on the latter's birthday.
And this philosophy was all wrong and should be thrown into the trash can, so Shen Jingwei thought in resentment.
Clearly, tonight, he lost everything he had to Yan Renzhong. He had allowed Yan Renzhong to play with him in many, many ways, and entered the hole that had never before been breached by anyone.
So whose birthday was it, again?
Who was giving something to whom?
These thought circulated in Shen Jingwei's mind, a coping mechanism to enduring Yan Renzhong's entry.
Shen Jingwei was kneeling on the bed, his legs spread wide by Yan Renzhong's. The man himself was holding Shen Jingwei's waist up as he slowly lowered Shen Jingwei onto his erect member.
