Lube his finger

Carl lubed up his index finger. He was going to savour this moment.

"OK, I'm going to lube you up a bit first as I think you'll need some before we start."

"OK, just be gentle..." said Steffi.

Carl could be nice and simply lube her up for the thermometer, or go further. He spread her cheeks looking at her pink rosebud. It tensed up as soon as he spread her.
