Curious, Jeff browsed through the available options, and his eye was caught by the choice to become alcohol. He had tried drinking with his friends once or twice but was always embarrassed by his total inability to hold his beer.
Maybe if he had actually been beer for a while, he might find it easier to digest. He hadn't had any plans for the next few hours anyway, so what's the worst that could happen?
He began checking out his house for something to contain himself in, and was surprised to find a large empty keg right by the garbage bin in his kitchen. He dragged it upstairs, opening up the top and standing uncomfortably in the cold metal as he set the options on the program.
He decided to give himself twelve hours as alcohol, thinking it would make for a nice rest and he would be ensured that no one would interrupt during that time. But as he confirmed, he realized perhaps he should have removed his clothes.
This problem was soon resolved as he felt a tingling sensation against his skin, and his clothes began to turn white and fluffy, before getting much lighter, the fabric becoming bubbly froth which spilled into the keg, making the "head" for the drink he would soon become.
Jeff hiccuped, feeling oddly happy and quite aroused standing naked in the froth. Slowly he reached down to stroke his hard cock, and before he had even completed three strokes he felt an orgasm rush through him, and orgasm that didn't stop. He managed to open his eyes as he struggled with the pleasure, to see that instead of cum, his cock was producing a thick stream of brown, strong-smelling liquid.
"Oh god...this is it..."
He struggled to get a hold of himself, but the pleasure was too much, and he felt the taste of beer rush across his tongue as it began to flow from his mouth too. The froth beneath him rose up, lifted by the warm beer underneath it. Jeff felt himself sinking, his legs becoming weak, then slowly numb until he couldn't feel them at all. He looked down to see that they had vanished, turned completely into booze.
Jeff groaned with pleasure, his hands slipping from his cock as his body was coated with wet beer, his arms turning limp as they wobbled, then collapsed into fluid, his torso bucking as it sank lower into the liquid, until only his head was poking up over the froth, and with a blinding flash of pleasure he felt an explosion of joy overcome him.
When he came to, he felt odd, almost incorporeal. His vision was blurry and brown, and he could see bubbles. The smell and taste of beer seemed to be everywhere. He tried moving, and felt his whole body flow back and forth in the metal keg. He was a keg of beer, he was stuck like that for the night, and it felt great.
