This spurred me on and I began to move my hand down her body, moving lightly and slowly. She began to wiggle and move in response to my hand and I fin...ally took her nipple in my mouth. Her sharp intake of breath made me realize she hadn’t expected it. While I sucked and licked her nipple, my hand got ever closer to her sweet pussy. I knew from our talks that she kept it shaved and I couldn’t wait to get my hands on it. When my hand finally reached its destination, I laid the whole thing on top. "You can't get pregnant while you're breastfeeding, Marie. You produce hormones that are like birth control pills. Don't you know anything?"Marie thought about it for a moment. It sounded right. Did she read it on the Internet? "Really?" she asked."Of course. Ah, here we go..." Crystal moved to the side of the bed as a naked Kevin climbed on, his less-than-average-sized stiffy pointing toward his goal.Marie looked at it. It was thin, like a couple of pens tied together, and maybe 5 inches in. When I walked by I heard her say 'I'm serious!' and giggle. It piqued my interest and instantly got me hard, so I hovered around the door for a second to try to listen. I couldn't hear what he said, but then she said 'someone online said that's what happens.' I could hear him laugh and say 'maybe you're just used to it' or something and her laugh and then silence. After a moment she yelled out 'you don't believe me, do you? I swear, it got smaller.'Fuck, it hit me so hard haha. She was telling. .I unzip my trousers and expose my cock, she likes the look of it, hard and veiny, with a big puple head, I grab a handful of her hair and guide her mouth to my cock, she opens her mouth wide and slides as much down her throat as she can....I look over my shoulder, out of the window in the darkness I see you standing there looking at us, a look of lost bewilderment on your face, we havent even turned the cab interior lights off, you can see everything, my cock is now at the back of your wife's.
