Reach under my shorts and rub my cock while I watch her?

Watching Rochelle and rubbing my cock over my bathing suit was making me really horny! My cock was rock hard under my shorts. I looked back toward the stairs of the deck to make sure no one is coming back to the deck, and then I looked back to Rochelle and slid my hand underneath the waist band of my shorts. My hand lightly gripped my shaft and I slowly slid it up and down its length as I stared at Rochelle's ass.

God, if she would just turn again slightly so I could see her side-boob in her swimsuit, I would probably cum in my shorts!

There! She was turning slightly to grab another hot dog for the grill... No! Shit! She turned right around and looked right at me!!!

"What do you like on..." she started.

I whipped my hand out of my shorts faster than the Flash. My heart was pounding in my chest and my fucking cock was making a tent pole in my shorts. I tried to adjust my seating a little so it wouldn't be so noticeable. I think I succeeded. She continued to look at me and she only stopped talking for a split second though it seemed like minutes. Did she just see me with my hand down my shorts while looking at her? And if not, surely she saw my stiff erection practically poking through my swimsuit?

"Ketchup, mustard, relish?" she asked.

"Um," I said with a slightly quivering voice. "All three."
