Wolf had no trouble being bold, but he also clearly had the upper hand. Felix was going through emotional uncertainty, while Wolf was sitting on his high horse judging the poor guy. The playing field had been leveled considerably with Felix's confession, however, and Wolf was more than content to let the night take him wherever. He didn't know if Felix was ready to have sex or he merely wanted to kiss, but either way Wolf was fine to go along at his new playmate's pace. Not that his roll with the punches attitude meant he was about to let Felix call all the shots!
As soon as Wolf felt Felix's hand resting just above his kneecap, and did feel the vibrations buzz through Felix's lips, he knew they weren't going to part anytime soon unless Felix somehow got spooked, but Wolf was going to try his damnedest to keep Felix distracted from what was outside his room. Inside, no one could see or hear them, and as long as he could keep Felix's mind blissfully empty and in the moment, he was pretty sure there wouldn't be any problems.
He disengaged from the kiss and Felix's grasp (even though his fingers felt amazing in his hair), but for a good cause. Sitting on the edge of his mattress was going to get old fast, and Wolf wasn't going to wait around for the discomfort to settle in as his leg went numb or something, so he climbed entirely onto his bed and crooked his finger at Felix, indicating he should follow. After all, Wolf couldn't kiss him when Felix was all the way over there on the other side of the bed.
