Yes, get them to join you naked

"Okay ladies." I said, "I think we need to try something here."

"What do you mean?" Mia asked from her position quickly yanking her hand out of her pants and pausing the movie just as the father was about to enter his oldest daughter.

"Well, I feel a little singled out being the only one naked here. And I can tell you three want to have some fun because the movie is getting you three horny." I said as I was cut off by protests from all three.

"Now stop. Riley you are practically grinding yourself on the edge of the chair. {Bella} you have your hands down your pants and you are playing with your tits. Mia I can very clearly see that you were playing with your pussy. So why hide it. Make your lives easier and join me naked. We can watch the rest of the movie naked. It will be fun."

"You just want to see us naked." Mia accused me.

"I already saw you naked." I said causing Mia to blush and {Bella} to get confused considering she didn't know about that yet.

"But you are right. I would love to see you all naked. What sane straight guy wouldn't? But I really do think it would be easier for you girls to play with yourselves if you had no clothes on. So what do you say?"
