No, but Nate does

You look down into Molly's eyes and see she doesn't want to give up her bone. Thankfully Nate is now siting up in an armchair across the room, and has apparently been watching. "I've got some for you" he says, stroking his cock.

Your Mom, heads over and drops to her knees, from your angle you can only see her from behind, her head bobbing up and down, but the smile on Nate's face reminds you that she's an expert.

Meanwhile, Molly is happily suckling lightly on your shaft and rolling your balls in her fingers. You like back, hands behind your head and close your eyes, letting the horny little creature play happily.

"Mmm, Tastes like Molly" your Mom says between mouthfulls. "Did you have a good time, dear?"

"Mmmhmm" Molly replies, not letting your cock go.

Finally the pressure builds too high. You roll over, forcing your sister onto her back, straddling her shoulders. You fuck her cute little face forcefully until your cock throbs, then bam! she chokes as the first load hits the back of her throat, she manages to swallow the rest but when you pull your cock out it's slippry with a mixture of saliva and the cum that's now coating her mouth. You hold your cock in your hand and wipe it across her face.

Molly smiles as you climb off her and drifts back to sleep.
