Aaron and Joe were laying on the beach when it hit them. A sudden intense wave slammed them and they were pulled into the depths.
When they came to, they found themselves on a different shore without any clue what happened. They got up, muscles throbbing in pain. They hadn't realized yet but their muscles were beginning to grow. Their gold and blue speedos, respectively, had ripped away as their nice
enough asses filled out forming magnificent bubble butts to match the perfectly sculpted pecs growing on their chests. Tiny scales matching their now lost bikini briefs were beginning to cover their muscled legs and lightly flecking their torsos like body hair. Their feet were beginning to shift into fins.
"Good. Your awake."
They turned startled to see an incredibly handsome tanned man with short dark hair and beard swim towards them.
"I was worried you wouldn't come to and your scales are coming in nicely."
Changes? They both looked down, suddenly aware of their bodies. Their legs were beginning to merge. Aaron's tail forming gold and green scales, whilst Joe's were coming in blue and copper. They were also hard as rocks.
"Such handsome mermen"
Looking up again the noticed the man... merman pull himself up showing off his huge black tail with its brilliant fin glinting purple in the sun. Fine irridescant scales framed his magnificent ass and powerful washboard abs as they faded into the glistening human flesh of his torso. He sat up between them, his long changed cock jutting proudly from a slit in his tail bejeweled with tiny soft scales forming a treasure trail towards his belly button.
He placed each hand on their hips, gently caressing the newly formed scales on their now joined thighs driving them wild with lust. Their own cocks, nestled in a depression formed by the seam where their legs once were separate, twitched in anticipation as his hands slowly made their way towards them.
"I'm Mike, by the way" he said before kissing each of his new pod mates passionately and gently stroked each of their changing members.
"Aaron"
"Joe"
They each began nuzzling his neck as they played with his chest. Mike caressed their heads and upper backs as they made their way to his cock, feeling and lapping at every inch of his torso. They paid extra attention to his nipples which made him moan in intense pleasure. As they reached his cock head they began to lap and lick, kissing over the head and taking turns sucking on it. Expansive jewel toned fins formed from their feet to rival Mike's making him so proud of his new brothers.
Noticing their cocks stretching and extending he pulled them up to kiss them passionately. Their cocks coiled around each other, creating a powerful knot of writhing members. Their well muscled tails wrapped around his and they became a tangle of fins and limbs. Kissing and licking, coiling and thrusting. They rolled into the surf as they did so, the cool water rushing into their gills amplifying their lust. Backs, pecs, arms, faces and still very human asses squeezed and carassed.
Their ministrations became more intense as each of their cocks found the slit at the base of another and entered, uniting them in mind-blowing ecstasy as their now much more sensitive prostates were massaged.
Eventually they burst in unison, filling the water with a mist of cum that would later attract females to have their own fun. Leaving the male eggs to be claimed by their fathers and gestating the girls themselves.
For now, the three gorgeous mermen settled on the ocean floor, cuddling and resting; black and purple, green and gold, blue and copper. Now longer black hair with an irridescant purple sheen floated around Mike's head, blending with Aaron's brown with green and Joe's strawberry blonde with blue and copper. Their beards gently exfoliating each others faces as they nuzzled each other. A new pod joined in the bond of love.
