She was trying to geth both cock's in her mouth.

She soon has you both in front of her, holding your cocks together, rubbing them around her lips and trying to get them both in her mouth at the same time, as she moans in delight. David eventually decides that you stand her up, bent her over the backrest, and fuck her from behind to see if that helps.

You take turns to grip her warm soft hips and steadily pump her full of cock. As the pace builds up she is whimpering and groaning until you can hold back no longer, "This is just too good," you sigh, "It's like my first fuck, only better! I've just got to shoot my load again! Hold on girl!"

With loud grunts, your thrusts go faster until you are slapping against her bum again, making her hips ripple. "Go on John, fuck me! Fuck me hard, that's it hard. Oh yes, Yes, Yes!" As she encourages you to fuck her harder and harder, you let out a loud groan as you empty your loaded balls into her once more. "That's it! That's it!" she pants, pushing back onto you. "Ooh yesss, John!"

As soon as you are finished, David takes your place. Marlies her pussy is mushy and feels like a bath of warm oil as her husband’s cock slides into the drenched combination of your juices, he soon feels the pressure starting to rise. He lifts her higher over the chair back so that her feet are off the ground and he begins fucking her for all he is worth.

"Oh yes! Oh David yes!" she cries. "That's fantastic, don't let it stop, please don't let it stop!" But it is to late, he feels the sap rising and her pleads are only adding to the excitement, there is no going back now, with a few final thrusts her husband’s cum is soon spurting like a torrid jet to join yours deep inside his wife.
