Bubble bubble toil and trouble

Turning to you with a sickly grin, she begins to hike up her skirt to show you the results of her spell.

A purple light begins to fade from her bulging panties. She slips her fingers under the waist band and gently tugs them down, revealing a 5 inch erect cock!

You stare at her in complete shock and dismay as you begin to comprehend what had just happened. Not realizing you had somehow fallen onto the floor, you attempt to flip yourself over onto your stomach. Your still erect and sensitive dick hits the hardwood floor and you moan in ecstasy. Your grind against the floor for release, your feet kicking off your pants and undergarments in the process. After calming down you attempt to sit up, this time using an overturned table that fell over with you as leverage. The witch watches you with a anticipatory smirk, as you get to your knees. As you attempt to get to your feet a familiar feeling hits you. A pulse heads from your stomach and down through your bowels and bladder. Your entire body begins to feel hot again as you look down at the sweat-soaked shirt clinging to your chest. You begin to see a faint green glow emanating from your stomach and crotch. Taking all your strength, you remove your shirt to get a better look.

The witch begins to gleefully jump up and down, her new member bouncing with her.

“Oh goodie, the spell is working even better than expected! Usually I can only gain a quarter of an inch at a time, but now we’re really cookin’! With every inch I gain, my witches semen becomes even more potent for my potions. You’ve got quite a bit more to give! My previous sacrifices have had enough strength to run away, but it looks like you’re too weak to leave the spell’s range.”

A bead of sweat travels from your forehead down between your pecs, follows the trail down your glowing stomach to rest on your pre-cum dripping 5 inch dick. The pulses begin again, only this time faster and somehow more intense. Your arms feel like bricks as you brace your palms against the floor and rest on your haunches. You involuntarily start to arch your back as the pulsing begins to shift lower. All of your focus is on the green **** as you watch it begin to move down to your balls. You watch in horror as your sack begins to expand, glowing brighter and brighter.
