You can't imagine how sensitive is Ethan when it comes to tickling him. It was one of the times we decided to change our roles - this time he was tied to the bed. So, why not use the opportunity and play with him for a while? I tickled him for a few minutes, while he was wriggling and shouting, but after that it was time for a reward - I made him cum. However, that would be too easy if I just let him go after he came. In the end, you can see him wriggling again in his ties - that was caused by a post-cum teasing I did!
