Geoffrey and Virginia were cruise ship veterans. After Geoff had retired, the elderly couple spend their savings sailing around on luxury cruises. The two of them were happy in their sunset years.
When Virginia first heard of the life-rejuvenating properties of mutant semen, she was excited. Her body had become old and brittle. Mutating could give her a new lease on life. Geoffrey disagreed. Mutations were very unpredictable. You could add decades to your life only to spend it as a completely helpless blob. That was hardly even living. Not to mention the legality of it. Geoffrey and Virginia's different perspectives led to bickering led to inaction. However, Cafly way about to make the decision for them.
The happy couple were asleep in their cabin. An anomalous, pink ooze dripped into the room. Cafly reformed her body. She knelt at the foot of their bed. She pointed two of her three cocks at the faces of the unsuspecting couple. Then, she worked her shafts.
Geoffrey woke up as something splashed against his face. He was startled and stumbled out of bed. He clambered to his feet and wiped the liquid off his face. Only then did he realize what had happened.
Geoffrey's shoulders slumped as the fat that clung onto his old bones melted away and redistributed itself. His hips grew wider his skin rejuvenated itself. His flabby, old-man tits swelled as they mutated into the real deal and grew to be as large as cantaloupes. 5 additional nipples appeared on his chest. Three were in a row below his original set and the remaining two were in a third row below that.
Geoffrey's dick was the next to change. His penis grew bigger and bigger. Until it was roughly as long as his torso and had balls that hung tobhis knees. The pleasure he felt was mind-melting- literally- as his neck and head sank into his shoulders. Only smooth flesh remained between his shoulders.
Brown hair started to grow out Geoffrey's restored foreskin. Blind hands stumbled as they struggled to find the erect hyper-penis in front of them. Geoffrey breathed in with his new mouth for the first time as the curtain of skin with lifted. Geoffrey's now very feminine head was attached to massive cock that was attached from between her legs.

Virginia gasped and sputtered. She threw the blankets away and wiped the sticky liquid off her face. Once she saw the pink giantess sitting before her, she knew it was already over.
Virginia felt a weight growing on her face. She used her hands to inspect her lips. She could feel her lips becoming thicker by the second. Then, her lips grew away form her face. Flesh filled the gap left behind. Her mouth hang off of her face like an elephant's trunk.
Virginia went cross-eyed looking at what had become of her face. But, not for long as her eyelids swelled as transformed into two, new, fat lips. Her newest mutations extended away from her face in the same way her original mouth had.
Virginia's nose transformed into a singular eye. Her arms vanished without a trace. Her rump shifted and morphed as two feet grew to replace her ass with the accompanying legs soon to follow.
Virginia's mutations finished with her wrinkled, tanned skin regaining it's youthful vitality. Her gray, thinning hair changed to be a brilliant and full head of snow-white hair.

Geoffrey stared across the room to the woman that had been the love of her life. Everything about the both of them had changed. Geoffrey gazed into the deep, loving eye of his wife, taking the moment to drink from it.
"What are you waiting for Geoff, kiss me!" Virginia spoke with all three of her mouths.
Geoff joined Virginia on the bed. She kissed the lips that had formally been Virginia's right eye. The kiss didn't stay just a kiss for very long as Virginia's lips stretched around Geoffrey's dickhead and started to suck-off her whole shaft.
Cafly, satisfied with her work, left the two lovebirds alone. She dissolved her body into its liquid state. She slid under the door she came in through and searched for new victims.
