Pull out and hose the mother's butt with cum

You feel the cum boiling up in your balls and pull out just before you fire off. Jet after jet of sperm coats the mom's lovely rump. Finally you stop shooting. You take a step back to admire the view.
"Oh... my... God..." the mom gasps, slowly coming down from her climax. "That was... that was..."She reaches behind her and scoops up some of your cum, licking it off her fingers. "Mmmmmm," she purrs. She turns her head and you give her a smile.
"Brandon..." she says slowly, trying to formulate her thoughts. "Um... we shouldn't..."
You reach over, turn her to face you and hold her body tightly against your own.
"You liked that," you say, softly kissing her neck. Her body shivers at the touch of your lips.
"Yes... well... I'm your mom... it's..." she stammers, still in a bit of a sexual daze.
You purr, "If it feels good... it's right." You kiss your way to her chest and she lets out a soft moan as your lips kiss her cleavage.
