They were just in a soundproof room in their lab. Because it was partially made of glass, she could see her sisters. When Mary looked shocked and then... looked at her, she got really nervous.After what seemed like ages, her sisters came back, and Mary said, “I need you to pee in this cup.”“Gross. Why do you want me to do that?” asked Joni.“There is another way. But if what we suspect is going on, it might not be very safe,” Susan added.“What she means is Mom and Dad might find out,” Mary told. Smiling at her accomplishment, Madge put the brush down and began with afinishing powder to set the look. She finished up with a liberal amountof a strong floral perfume. Tim's eyes burned slightly causing him toblink and he coughed a bit as the perfume encircled his head.Almost finished, Madge picked up a brush and comb once again, to tightenand freshen Tim's ladylike vintage hair set that had been tussled a bitfrom a sleepless night. Soon his curls were once again lacquered tight.She then. ‘Okay, I can do that, but I really have to go!’ My mother stated less than forcefully as I slowly plowed my cock into her ass. To prove a point, I pulled up almost all the way out from her anus and pushed back in, a little harder and faster, all she could do was forcefully set her hand down on the bed and grip the sheets tight. I let out a long sigh as I pulled my penis out almost all the way and pushed it back in, I knew she was open enough to accept me without pain and shifted from moving. She was really pumping my face and I could hardly breathe, as myMistress was getting wetter and wetter. Her smell was musky and strong. I gasped for air as my tongue licked her clitty and vaginal lips. It wasonly a few seconds later that Laura clasped my head between her thighsand moaned of pleasure and orgasm. I was being smothered by cunt andloved/hated it. All this time my hands had been cuffed behind me, andthey were starting to ache. But I had this feeling that my Mistressdidn't.
