Rex's cock immediately slipped into my mouth. It was big and slimy, and I had to open my mouth wider to fit him in. His cock sunk in as far as it coul... go.Daddy used his hold on my hair to move me back and forth, Rex's cock sliding in and out of my mouth. Rex sighed, wagging his tail slowly as his cock was serviced. I could only take his cock up to his knot, but Rex didn't seem to mind. He humped his hips a little, and I gagged on his cock."Keep sucking!" Daddy told me, and I let out another. Laughing, you push my hands away, kneeling down in front of me. You deftly undo the button, pull the zipper down and slide my jeans down over my hips to my knees. My cock head peeks from the waistband of my underpants twitching like a caged animal. You reach in and your hands begin to stroke my hard shaft sending a new rush of blood into my already engorged cock. “I want a shower.” “We had one before we went out.” “I want to get the smells of the city off my body. I want to feel really clean.. I slowly undo the bottom and unzip your jeans and take them off, only for you to flip me back over to do the same. You start to dry hump me, and we just can't seem to stop the yearning to just fuck wherever we are to get to the bedroom, but then I get you up and you wrap your legs around me as so take you into the bedroom and toss you onto the bed. I turn around slowly, methodically bending over and pulling my underwear down and off so that u get a a very nice view. I look over my shoulder. “Just a guess. Don’t worry it doesn’t show ... yet! Whose is it?” he inquired.“It could be yours you know,” Yvonne said, “In fact I think it is.”“Do you really think so?” he asked.“Don’t be...” her mother started but she was interrupted as David continued, “If you think so we should make a fortune, or at least medical history. Except for the first time, and you’ve had at least one period since then, you’ve only swallowed my cum. You may not have been told but you can’t get pregnant from.
