Maybe Tanner didn't have any experience, but that definitely didn't stop everything that he was doing from feeling incredible. Very quickly, Keith found himself hardening, becoming more and more desperate for more of those touches, more of the complimentary comments that Tanner dispensed so effortlessly. He knew he'd never been this hard before in his life, never wanted anything this badly. "Tanner... don't stop..." He murmured the words softly, pressing himself up into Tanner's hand, encouraging him to stroke him more.
Once they were both stripped down to only their underwear, Keith knelt between his legs, and his lips teased down over the teenager's stomach, lower and lower, closer to his waistband. His breath barly ghosted over that tempting bulge, and his eyes were locked with Tanner's, carefully monitering his reactions to make sure everything he was doing was fine with Tanner, that he liked it.
Despite the undoubted desire he had for Tanner, Keith didn't make a move to take off his underwear until he was given permission, and he saw how sincere it was, how much Tanner clearly wanted him. But he didn't waste any time, once he had that permission. Immediately, his fingers, which had been teasing at the waistband, hooked more firmly and dragged the last piece of Tanner's clothing down his legs, freeing his erection and leaving him fully naked.
Once that was done, Keith just looked at Tanner for a moment or two, the expression on his face slightly awed. The young man was beautiful, there was no other way to describe him. He was, in fact, the most gorgeous thing that Keith had ever seen. Carefully, he reached out and wrapped his hand around him, stroking him slowly but firmly, fingers wrapped around his shaft. But even that wasn't enough, and he soon bent down, brushing his lips very lightly against his hardness, exploring this, too.
