Sirius gave the hand a squeeze before he wrapped both of his arms around Remus' middle. His knees dug into the ground which gave him just enough leverage to pull Remus back into his chest. Holding tightly as if he might never let go, Sirius let out a shaky chuckle.

"I--" he started and then stopped, finding words completely unnecessary. All he needed or wanted was to continue holding Remus until he asked him to stop.
