Grow his cock back into my tits

"Grow his cock back into my tits," Mom's inner voice aggressively demanded.

Another bolt of energy coursed through my veins. I couldn't see what was happening because of the huge mass of soft boob in my face, but I could feel my shaft thickening and lengthening in my hand as I jerked. The head of my cock bumped into the underside of my mom's gigantic super-jugs and kept expanding, forcing its way between them. Mom moaned in ecstasy as my thick rod stimulated her hyper-sensitive bust.

"Fuck them honey," she commanded out loud.

I obediently sandwiched her breasts around my shaft and thrust into them with manic fervor.

"mmhHMM BIGGER cock," Mom commanded lustily.

More energy shocked into my system. The head of my cock continued growing out of my Mom's breasts and into the cool air of the cave. I felt Mom's warm wet tongue licking the underside of my elongating shaft. Her moans rapidly increased in volume as I sucked and fucked her glorious rack. The sensitivity must have been better than I expected because it only took about 20 pumps for her to reach a second breast-gasm. She shrieked as her fat nipple pulsed in my mouth, cups of cool milk spurting out. I drank it down eagerly.

"CUM for mommy!" Mom's thoughts screamed, mid-orgasm.

Another blast of mystical energy, this time it raced straight to my groin. I involuntarily erupted between Mom's tits.

"HAaa!" I let out a muffled yell of surprise into my mother's huge breast.

Hot thick batter shot out of my pulsing column of man-meat above our heads. All blood drained from my head and was replaced with a tidal wave of pleasure. Through the haze of ecstasy, I could hear rope after rope of cum *glomp* onto the sand above us. My huge cock pulsed and my churning balls pumped for what seemed like an eternity.

"More! more!" Mom demanded, licking my pulsing cock shaft lovingly.

An endless supply of cum continued to blast out of my prick. The pleasure was becoming unbearable. My mind gave in to delirium and I drifted off into a deep sleep while still erupting away.
