Sometimes he feels as if God is testing him and it wasn't that he couldn't control himself, it was because his body didn't like listening to him. So when Antonio steps out of that shower smelling fresh as a baby wearing that shirt, he curses at himself and averts his eyes.
Lovino knew he wasn't the honest type but what he lacks in honesty his body made up for it. It made him too predictable, which was bothersome, and he thanks God that Antonio was born so oblivious sometimes.
At that moment he prayed that Antonio was still oblivious so he wouldn't notice how his cheeks were tinted with a slight red, his eyes wandering too much, and his thoughts somewhere indecent. It was as if his mind wanted to reach out and run its fingers over the other's exposed skin. Dig its nails into it before it would travel down to where the soft peaks of Antonio's nipples laid and rub them.
And maybe, if the other was in the mood, well…
There were too many thoughts. Too many thoughts that rushed themselves to his crotch so he quickly leaves the room and damn the man for being so attractive without trying. The rest of time Antonio continues wearing the shirt he finds his interest for random furniture in the house increases and somewhere in the back of his head, though he'll deny it, he hopes that those thoughts will come true.
