Really, Sam hadn't done this for years. Lucifer didn't bathe with him any more, and so he hadn't had any practice recently, hadn't had any need to do more than make sure that he could keep holding his breath, just in case. One day, he'd be grateful that he could.

Right now, though, Sam just needed to test himself once, get his bearings before he tried to do anything more complicated than just go below the water.

He languished attention on Eliot's nipple just for twenty seconds or so, then resurfaced, taking a breath, then exhaling low, emptying his lungs all the way. He took a deep breath, slowly, drawing it down to his core, and then ducked forward, bending into Eliot's lap. His hand smoothed up, guiding his half hard erection into his mouth, taking the tip in firmly so that he could seal it with his lips, and swallowing the warm bathwater that went in with it, so that there was no risk of it dripping into his lungs and making him cough.

He tongued the head, tip delving against the slit suggestively, teasing at the vaguest taste of him that hung underneath the cleansing water. He bobbed down further, encompassing more of Eliot as he came into his own, erection filling under the efforts of Sam's teasing.
