Thank you for your comment.
In this scene, he doesn't have an erection yet, so maybe his pre-cum isn't dripping.
The tickling scene is also planned to be drawn in the manga version. Eventually, Yuta will start to feel sexual about tickling as well.
Wow wow wow! Please continue this scene. So very sexy. His most exposed parts, he can’t hide and they’re being used against him. He has to succumb to the pleasure at some point. Great great job! Thank you for inspiring so many thoughts about this.
