Summer Holiday/Spain Day 2 Hang by the pool

I had a nice long shower, then picked up my Kindle and went down to the pool for some lunch.

I opted for a healthy salad and sat down under a sunshade to read for a while. Inevitably, my eyelids drooped and I fell asleep.

I was lying on the beach, naked and a pair of twin girls were standing beside me, pointing at my stiff cock and giggling. I pretended to be asleep as they moved closer but couldn't resist opening my eyes a slit as they reached out to touch it.

They didn't seem to care if I was awake or not, and when one of them have my nob head a lick, I lifted my head to get a better view. The other twin nudged her sister and the both grinned at me before taking it in turns to suck the swollen head of my cock into their small mouths.

I waited, enjoying the sight and sensation, until, as if by some signal, they both stood up. I though that was the end, but they were just changing position. One of them stepped over my legs and stood astride my thighs; then she climbed forward until she was sitting astride my cock. The other twin stood beside my head and when I turned, I had a close-up view of a perfect little pussy.

I once saw a cartoon of a man on a beach with a girl using his cock and another using his mouth. Now that man was me, and my cock was trapped in the vice-like grip of a five-year-old cunt, while my tongue was exploring another one.

The two girls from before were standing in front of me and giggling. The object of their mirth was clear to see as the leg of my shorts had ridden up and my cock-head was poking out.

What do you do?

Pull my shorts up more so they can get a better look

Blush and pull the leg of my shorts down
