Percy wasn't very experienced, or at all, but it felt so natural that he relaxed even more, enjoying the feel of Cass' fingers and cock moving around him.
"So good," he muttered into the kiss, not sure that Cass had even understood, but it was irrelevant. What mattered was all the sensations that Cass was causing, sensations that were foreign to Percy. It had been too long, and within minutes his body was as tense as a coiled spring. When Cass rubbed the head of his cock on the upstroke, all tension was released as he came all over their body, shaking with the intensity and with Cass' name on his lips.
