He might run the risk of growing too affectionate with how comfortable he's growing. It makes him a little more free with where he places his hands on the swordsman, how his thumbs make small circles against the fabric of his clothing about just where he's contemplating putting marks. Somewhere high enough for the whole fucking world to see his ownership sucked in a dark bruise on Squalo's throat.

"I'll see about getting you a special job, just so you can find out." Because he can spoil Squalo when he chooses. Though it's probably not really spoiling if it's Xanxus getting the contract. He always tends to go for the most difficult things, always up to throw the man he firmly believes it the best swordsman in the fucking world against jobs considered impossible by sane standards.

"Like you'd let me forget. You bitch too much too loudly for me to ignore, you mouthy fuck." The fondness in his voice can't be avoided and he hides it by responding to the tug of teeth by surging forward to give the man a punishing kiss that's certain to leave lips swollen. Only when he's certain of that does he pull back with a dark smirk. "That's also something I'm not going to forget." Anyone who dared to think they could take Squalo from him...well, they wouldn't live long enough to realize their mistake.
