Once Kit sunk all the way down like that with his fangs and everything, Booker was a complete gonner. There was no control or holding back left. Throwing his head back, there was a mixture of a cry, a moan and the words 'fuck, Kit'. Only seconds later he was cumming, completely forgetting about not wanting to do it in his mouth. For a few moments, all he could think about was his climax because of the older vampire.
When it was over, he slouched and let out a shakey laugh, hands going down to carress Kit's face, trying to pull him up.
