Unexpected Connections in a Hot Tub

Cabin part 2... so finally we said what the hell and we all got in the hot tub naked with our drinks as the sun was setting. I said let's talk about the elephant in the room. Mike stood up with his cock in his hand and said who me, it's not elephant trunk size. But it was at least 9 inches. My 7 was jealous.

We app agreed probably because it was the easiest way to keep things moving. It started off slow.
