The finger was actually a bit unexpected, and it woke Kevin right away. If Lambert had put it on him while he was asleep, Moore might wake up slightly shocked.
Jack really was a very caring lover and fair partner. Both must have had pleasure in having sex, although Kevin had long noticed that Lambert was particularly careful with Moore's pleasures.
Kevin sighed, relaxing under Jack's caress. The driver sucked it greedily, licked it and swallowed it, not forgetting the vigorous but careful movements of his finger at the same time.
"Oh, Jack ..." Moore moaned. "I don't know how long you caressed me with your hand, but I already ..."
Lambert, of course, knew it well. He must have sensed the changes that were happening instantly in Kevin's penis, which was after all swallowed up by Jack's mouth. He knew and expected it with the excitement of how hard he drilled a finger into his lover's ass.
