A semi-solid sourish food prepared from milk fermented by added bacteria, often sweetened and flavoured.
I opened the fridge and saw the yougurt cup. I proceeded to open the lid, inserting my rock-hard cock into the sloppy yogurt. I then repeatedly fucked the yogurt and was satisfied by the moist slopping sound and the rippling through the yogurt. I then finished in the yogurt cup and proceeded to place the lid back on and put it back in the fridge.
