Both of them might not have been so eager to touch each other if they could have at least been busy with something to vent their excess energy.
Unfortunately, they only stayed in their RV as they hadn't encountered anything in particular that they needed to solve by themselves.
Treyton could only continue training his ability, while Luciel spent his time watching movies or doing other things.
Treyton also didn't stay well-behaved even though he knew they couldn't do anything further.
He would passionately kiss and touch Luciel from time to time when nobody was paying attention to them, especially when they were on their bed at night.
So, Luciel, who could have just stayed well without any problem, was thoroughly provoked by Treyton, who couldn't find something else to use his excess energy for.
Of course, both of them couldn't be satisfied with just kisses and a few touches, and they ended up with unsatisfied desires.
