Sam is passed out

I glance over and see that Samantha's eyes are closed. I tap Megan on the shoulder. "Meg, Sam's asleep." That seems to be all she needs to hear because my wife immediately picks up her pace and soon she is taking most of my 8 inches into her throat. I suspect that having her sister passed out next to us is ramping up the excitement level for Meg too.

I don't know how much more of this I can take, and Meg must sense this because she pulls her head off my cock with an audible slurp and quickly drops her pants and underwear and prepares to mount me. I glance over one more time at Sam to verify that she's still asleep. And sure enough her head is gently cocked to the side resting on a pillow, the rest of her mostly covered under the blanket looking peaceful and snug. Meg sees me look at her and says, "I feel kind of naughty doing this right next to my sister."

I smile and say, "I think this does make you a little naughty." Meg just smiles back at me as she straddles me and aims my cock at her waiting pussy. We both let out a moan and she sinks down on my rod. Both of us glance over at Sam again. {If Megan ok with Samantha=true}

"Honey, since I let you feel up my sister earlier I want to know, who's got the nicer tits?" Meg smiles at me as she begins riding me.

I'm no idiot, "You of course baby."

She moans as she impales herself on me again, "I knew I married a smart man."
