Keep going

I'm in the bliss of finger fucking my wife under the blanket while her sister strokes my shaft. This could be amazing or terrible.

I decide to go all in. I maneuver my hand under the blanket to Sam's lap, slip inside her panties, and rub her soaking wet slit. She quietly gasps next to my ear. Her hand pauses a few seconds and then continues jerking me.

Sam's hand feels so good, I close my eyes for a few seconds. Meg shifts a little and then I feel her let go of my hand. Suddenly I'm full awake, hoping she doesn't go for my cock, already occupied by her sister's hand. Unfortunately, she does go for my cock.

I speed up my finger fucking to distract them, but to no avail. She touches my shaft and runs into Sam's hand on the downstroke. They both gasp and then Meg moans out loud as she shakes through a big climax, followed several seconds later by Sam squealing quietly as she comes as well.

I look back and forth between them as they look at the other. They laugh. Then they both throw off the blanket and Meg drops her mouth to my cock. Sam turns my head and kisses me with lots of tongue. I keep going at their pussies.
