"Oh Merlin. Please do not stop," he said in a low voice, as Theo's hand kept at it, working Greg closer and closer to that orgasm Greg had been dreaming about. He found himself moving into Theo's hand, fucking the fist the best that he could as he held onto Theo's ass.
"You..you did," he said, breathlessly as he felt himself ready, swelling and then with a loud gasp, bursting forth into the warm bubbly water. Theo's attention kept going, milking Greg's orgasm to the point of Greg gasping out and his whole body jerking. His free hand found Theo's and he stilled the movement, murmuring through his gasps, "Yes, yes. Loved it. Loved me. Sucking you there. You, you did it Theo," Greg said, pressing his lips to Theo's for a long deep kiss.
