Whatever Wolf had been expecting, it hadn't been for Felix to fold so easily. It wasn't as if he'd been resisting the subtle advances Wolf had been throwing out in the first place, but Wolf had seen Felix with girls. He was fully aware people weren't cookie-cutter straight or gay as he wasn't one of those people, but there really had never been any indication Wolf could see that made him think Felix could be attracted to men – not until he'd gotten him in his room alone.
Not that it mattered. Wolf didn't have to puzzle it out. Felix was kissing him back and that was all he had to care about. Well, that and he wanted to get the beer bottle out of his hand so he could touch Felix with both. The bottle cap was trapped beneath his hand against Felix's sweater, but when he broke free of Felix's somewhat cool grasp and lifted that hand to cup one side of Felix's face, he let the cap drop to the floor carelessly. It didn't make much of a sound against Wolf's carpet.
If he had been cautious before, he wasn't anymore. Wolf took advantage of Felix's parted lips and deepened the kiss with his tongue, uninterested in taking baby steps. They were both adults and, as far as Wolf knew, experienced (with which gender not important), so he let his body dictate to his brain. It decided it would be much happier flush against Felix, and it was Wolf's turn to feel a pleasant, consuming warmth wash through him.
