Kevin's cock consumes more lotion. Emily's vagina is in for a surprise.

"Hold up, let me try something..." his cock said as it spotted the empty bottle of Auto Masturbation Lotion on the floor.

“Hey Kevin, I hate to interrupt but you brought more than one bottle of the good stuff right?”, his cock inquired.

“Uh… yeah”, Kevin said as Emily’s breasts giggled.

“Go ahead hun, we’ll still be here,” her breasts stated in unison. Emily began to whimper as she was close to yet another orgasm thanks to the stimulation of her living breasts and vagina moving on their own. Sensing this her vagina began to massage her clit with it’s labia, laughing maniacally as Emily writhed in her restraints. As Emily was sent over the edge, her breasts growled and then began to make out with each other, causing Emily to scream as her next painful orgasm began to peak.

Kevin froze in awe of the strange but sexy sight in front of him as he grabbed his cock on instinct.

“Hey hey, snap out of it buddy!”, his cock exclaimed as it squirmed out of his hand.

“Right… sorry”, Kevin said as he shook his head and fumbled through his bag for another bottle of lotion.

“Okay, now what?”,Kevin said, holding the bottle below his waist.

“Unscrew the top and leave the rest to me”, his cock instructed. Kevin complied and his cock stuck the tip of it’s head in the bottle, sucking the contents inside itself. Kevin lost his balance as the intense yet alien feeling began to transform his genitals from the inside. A strange warmth enveloped his shaft and testicles as the empty bottle dropped to the floor.

“What the, what’s happening to me?”, Kevin asked as he began to freak out at the new development.

“Oh wow this is better than I thought. I feel great!”, Kevin’s cock exclaimed as his hips pulled him forward toward Emily once more. Before he could react, he tripped and fell on top of Emily, giving her breasts the opportunity to grab him by the neck and pull him in close.

“For fuck sake Kevin, please I can’t take anymore. I’m sorry okay?” Emily begged.

“Don’t listen to that dumb bitch. She humiliated you. She dumped you. Let us give you the attention you deserve”, her breasts said as one of the tiny mouths changed back to an erect nipple before plunging itself into his mouth. The other rubbed itself against his cheek while nibbling and whispering in his ear.

Alrighty handsome, show me this trick of yours?” Emily’s vagina said with a giggle. Kevin’s cock wasted no time as it grew like a tentacle, forcing itself inside Emily at such a speed her living vagina gagged in response. Emily’s vagina growled like a wildcat, as it contracted it’s walls, tightening itself to ensure maximum stimulation. Emily’s left breast began to moan as it rubbed it’s tit against Kevin’s playful tongue.

“Hey move over girl it’s my turn!”, her right breast exclaimed as it forced itself inside Kevin’s mouth, pushing her left tit out.

“Fine”, her left breast sighed.

Emily let out an ear piercing scream at the over-stimulation of her hypersensitive parts, ripping the sheets beneath her as yet another orgasm was forced out of her.

“Oh fuck, I think I’m going to cum”, Kevin said, gripping the bed as his cock sprayed it’s seed inside her. Once his dick retracted to it’s normal size he pulled away and watched as Emily’s vagina sucked his cum off it’s lips.

Emily felt a warmth envelope her entire body and shrieked when she suddenly could not move her arms or legs.

“Hey, Kevin! What the fuck is happening to me, I can’t move?!” Emily screamed.

“Go ahead and untie us Kevin. The restraints are no longer needed,” her vagina instructed as Kevin released the cuffs on her hands and feet.

“Whoa, what the fuck?!”, Emily screeched as her ass and legs scooted her and stood her up on their own.

“Wow, thanks for this Kevin. Now these beautiful legs are all mine.” Emily’s vagina said with glee as Emily jumped up and down against her will.

“Yeah, and these arms and hands are ours now. Now we can give ourselves a good massage anytime we want”, her breasts giggled as they squeezed themselves with her hands.

“No, stop!!”, Emily begged as her vagina excitedly sprinted her out the door.

“Hey, uh what exactly just happened?”, Kevin sheepishly asked his cock.

“Simple, I used your last bottle of lotion to transform myself. Now I can change my shape and grow at will. Not only that but my testicles produce an endless supply of nanites. When I fucked Emily, I pumped enough nanites inside her to reprogram her nervous system so that her vagina and breasts controlled everything from the neck down. In the process her ovaries were transformed in a similar way as my testicles. Anyone she fucks will be affected as if they used the Auto Masturbation Lotion themselves.” Kevin looked down in disbelief as his cock said these things and then had a perverted yet awful idea...
