Step Up With Me. With Me, #5

Richard "Tank" Martin was a big boy from the start. Born weighing over 11 pounds, he didn't stop growing. When he was in middle school, a football coach took him under his wing and finally explained to him the mystery of calories in, calories out and from then on it was all good for him. At least he thought. Being called to meet with his platoon sergeant and told that he was now part of the Army's overweight program, sent him into a spin that only his crews can help him out of.
Dr. Jack Dillon thought his life was good and finally settled. Part of an active veterinarian practice, volunteering with a service dog organization, spoiling his sister's triplets and training in sports ju-jitsu.the only this missing was a partner. He never thought that his world could be shattered with just a phone call even after being around his military friends. Tank and Jack have been dancing around each other for months until Tank takes a chance and kisses Jack at their friends' wedding moving their slow dance into a heated bump and grind.
Can these two survive the changes coming their ways together or will all the changes break them apart?
