Jack growled slightly, hips hips starting to thrust into Mac's hand. "Mac....it's...you're amazing" he whimpered, feeling himself getting closer and closer to release. His arms wrapped around Mac's neck, fingers entangling Mac's hair.
It only took a few more moments for Jack to come completely undone. His body relaxed in Mac's arms only a few more moments after releasing, but his arms still held Mac close. "I love you" he purred out, nuzzling into Mac's neck.
