Hunter is enjoying the show

"God that's hot. Shit."

Startled I turned to the source of the voice and saw Hunter standing next to us with his hand wrapped around his exposed dick. "Hunter! Dude, busy here. Go away."

"Well I can see that you are busy but I caught Riley and tossed her in the pool. But I didn't want to strip my sister so I came to get you and found you here with your sister. You didn't notice me and you two looked pretty hot, so I decided to stay and watch."

"Look, just go keep an eye on the three girls we already have naked so that we don't lose them. I will go get your sister. And don't mention this to anyone else."

"Well, what do I get if I don't mention it?"

Glancing at me sister, I turned back to Hunter and said, "She'll let you kiss her and your hands can only touch her ass. When she is done, you are done. Got I?" I said with a very threatening look.

"Got it." Hunter responded throwing up his hands as if to ward me off.

Getting up, I took off after Noelle leaving Hunter and my sister alone. Lucky for him, he did no more than we gave him permission to do. He did get lucky though because he got to feel my sister's ass and got to feel his dick pressed against her smooth stomach.
