Ivan felt very happy as he watched his boyfriend moving himself up and down, making the former feel the pressure, warmth, and smoothness inside the latter. Dino, who still was not used to doing it with him on the top, somehow felt embarrassed doing it yet he continued with it since he wanted to do it for Ivan. The feeling of the hardness and large size of Ivan's manhood inside himself was worth it for what he was currently doing.
[I can do this.] Dino thought determinedly as he continued to move himself up and down. [If it's for Ivan, I can do it!]
As he continued to watch his lover doing it, Ivan instinctively touched Dino's tits, making the latter feel ticklish. This made Dino feel a more intense wave of pleasure than before as indicated by the hardening of his tits. As much as he loved feeling Ivan's large hands on his tits, Dino found his lover to be touching them rather roughly, so he knew he needed to tell Ivan to be more gentle.
