Yes

"Um... yeah... sure," I answered, not quite sure what was going to happen next. This wasn't turning out exactly as I had expected but, hell, I sure was having fun.

"Ok, so now you have to decide whose ass you like better," Lizz grinned at me then at Ash. She turned her back to me and nudged Ash to do the same.

"Well, what do you think, little brother?" Lizz asked me over her shoulder. She wiggled her ass for me and Ash did the same. "Take your time, get a good look. You probably want to get a good feel too," she suggested with a wicked grin.

I moved up a little closer and bent down a little, looking from one to the other. They were both smooth and round, although Lizz’s was again a little bigger. But I kind of favored Ash’s petite little butt. I had actually admired it for some time now but we were just friends and I hadn’t tried anything. And then tonight happened.

They both bent over slightly as I ran my hands over their smooth skin, one hand on each ass. Taking my time and feeling them all over and giving each cheek a few squeezes. They were both soft and smooth but Ash’s was a little firmer and I liked that.

Then Lizz bent over completely at the waist to where I could even see her pudenda poking out from between her cheeks. This caused me to turn my attention to her completely, rubbing her ass a little harder then running my fingers between her cheeks and feeling her soft mound from behind.

Ash looked over to see why I wasn’t feeling her butt anymore and saw what Lizz had done. So she bent over too and bumped her ass against Lizz’s.

“Hey, over here, big boy. Don’t ignore your date.”

I moved over to Ash and gave her ass the full treatment too, stroking and squeezing her cute little cheeks, sliding my fingers into her crack and even pushing at her pussy lips to open a little bit.

“Ok, ok, I think that’s enough time now,” Lizz stood up. “So what’s your verdict - big sister or girlfriend?”

“I’m afraid I have to go with Ash on this one,” I answered. “Her ass is so cute and perky. Sorry, sis. So what’s next?”
