Your mind quickly jumped to one branch of thoughts connected to Lauren’s remark over the experience. You clearly loved the feeling of having sex with a mermaid so what about giving the girls a chance to bang a Merman...
“Ring. I wish to be a merman worthy of these mermaids” you then announce. “Wait? Did you just-” Lauren started as your body underwent the change. Your legs were pulled together with your skin of everything below the waist both merging and shifting into deep white that matched your former trucks. What had once been toes shot out and spilt into branches with a transparent membrane forming among them to create your tailfin...
...even your upper body shifted as your muscles toned from the only slightly average build to one now typecast as a general all-round fitness lover, not super-sized muscles ready to bend high-grade steel beams, but still strong and healthy.
“Wow... you... you’re a dream boat” Molly muttered in wonder over the results. “Well... it was part of the wish” You confessed while leaning up a bit and rubbing the back of your head. “Why has your tail got a bulge though?” Molly then asked. You look down and see this bugle exactly where you’d earlier by location had a penis...
...of rather there was one until for some reason Lauren sneakily swam behind you and started fuddling you which resulting in a tentacle-like thing burst out with the same rushing feeling you usually got from being aroused. And admittedly this ‘tentacle’ did share a few characteristics with your penis, just longer looking and seemingly stretchable...
...apparently mermen had a very different design for sexual intercourse.
“ohhh... I wonder how deep this guy can go?” Molly pondered as she swam in front of you and eloped you in her arms, her vigina placed directly in place for your cock to enter her.
And you didn’t hold back and took your chance as you followed her lead. Your cock started borrowing itself into her. Your lips lock up. Your tails twisted together as your cock went deeper and deeper into Molly. Lauren, Amber and Veronica just watched in either wonder, confusion or jealousy as they watched.
It was clear though that Molly was enjoying it as much as you it seemed until finally after awhile of your cock not getting any deeper you unleashed was should clearly amount to galleons of your typical hot seed from your erection into her. To the point Molly and you to a lesser extent having an orgasm second after second until subconsciously the two of you parted.
“So... that’s what merfolk sex looks like from a...non-participant perspective” Veronica remarked. “These tails are more flexible then legs you know” Amber assured while Lauren swam up to you and Molly. “That...was amazing” you slowly profess. “Glad your happy” Lauren accepted before asking Molly “What about you Molly?”
