The last pearly ball out, Bones gave Kirk's cock one last, slow lick before sitting up. Bones was so hard he couldn't see straight, but fuck, watching Jim like this...

Bones slipped the dildo out of him, and breathing hard, he took the tube of lube, slicked Kirk's cock up once quickly and climbing on top of him, slid down on his shaft, his breath shuddering as he slipped all the way down, not touching Kirk in any other place but where they were joined.
