I love those details. Vegas is so caring in the series, he waited for Pete's consent. I think he was just teasing…
Yes and this is why Pete fell for him. Not for the pain or torture but this small details. Since Pete knew Vegas from before he mighthave been expecting it. He also saw how he treated Porsche. But suddenly this man made a whole 360? That's a side of him pete never knew about. The 'I don't hurt my lover' side.
