You *did* say that...

She helps you peel her sticky shorts off then folds them up and puts them aside. "You can wear them anytime. Ask me to blow a wad in them too, if you want," she says with a mischievious tone and a wink.
You look down at her cock and ask, "It looks slippery enough, doesn't it?"
"Yeah it does!" she happily exclaims. "Let me free these big titties of mine." She pulls off her shirt.
"What for?"
"'Cuz I bet you will love feeling their weight on your back!" She steps up to you, and turns you around by the shoulders. You feel her large chest press into your back as she pulls you close and wraps one arm around you. With the other, she is sliding her cock between your cheeks. She is definately slippery enough and she knows it. "I'm just making a mess, 'cuz I can!"
"I like feeling slippery, you can do that as much as you want!" You reach back and put your hands on her hips.
"Oh," is all she says. Maybe she was trying to play a game with you.
