A common name for a porno, though a cement mixer is a special type of porno where body parts are arranged in incredible artistic arrangements....like when you get a flower arrangement and they make em all pretty.
A foul joke/prank performed. While perturbed, you take a dump inside a laundry machine dryer thats filled with your white laundry. You then run the dryer to 'mix the cement' and leave hardened skid marks on the victim's wardrobe.
I went in to grab my whites from the dryer and found that I had received a cement mixer.
While an erect penis is inside an oriface, rotate your partner's body clockwise without removing your penis. For maximum stimulation, try the counter-clockwise method.
When a man slides his erect penis inside a woman's vagina to full length and begins to rotate his hips in a 360 degree circle, essentially stirring the juices inside her. Centrifugal force causes the penis to shift in in the opposite direction of the rotation. This is best done without a condom however, as the centrifugal friction may cause the condom to shift and/or break. You've been warned!
I attempted the "cement mixer" whilst my lady was cumming and she flooded the bed! Thank god the sheets weren't high thread count!!
