The following morning, he wakes up and decides to take Niora's hand, kiss it, then do to it what someone with a foot fetish would do to a female's foot.
Anything: including licking.
*and sucking*
But due to her having a tail, her human formed isn't until on land.
*he continues sucking on Niora's hand*
Niora wakes up.
*Lincoln stops playing with her hand*
Lincoln: Morning baby.
Niora: Morning, Lincoln.
Serena and the others wake up.
*Kema yawns while stretching her arms*
Serena: Today we take our Lil' Lincy to the lagoon.
Lincoln: Lagoon?
Serena: Yes.
Lincoln: Why?
Kema: To meet others.
Lincoln: Okay...
It cuts to them heading for the lagoon.
*Lincoln looks around*
It was full of mermaids.
Lincoln: ...
All the mermaids giggled upon seeing him.
*he blushes*
Lincoln: Wow, is this what you plan Serena?
Serena: Uh... why do you ask?
Lincoln: I was wondering.
Serena: *looks around*
Serena turns around and smirks knowing that her plan was working.
*Niora looks at Lincoln*
All the mermaids (including Serena) swim towards Lincoln and surround him with seductive smiles as they called him cute.
*he blushes brighter than last time*
Lincoln: This is new.
Kema: *flirts with him*
Lincoln looks down to see a lot of bras falling to the seafloor.
Lincoln: !
Lincoln looks up to see the mermaids all topless for him.
*his eyes widen in shock*
One of the mermaids pull his head and gets him to drink her milk.
*it tastes sweet*
He starts smiling as it tasted like strawberries.
*she runs out*
Soon a montage follows of him going to each mermaid and suckling on all of their milk.
*sometime later...*
Lincoln lays on the sand burping after his fill.
*a mermaid pours some water on him to keep him hydrated in his merfolk form*
Lincoln: Thanks for all that milk.
Mermaid: You're welcome.
He like it as his now fully extended harem cuddled him.
Lincoln: *sighs in pleasure*
Lincoln even thought about future plans with them.
*Niora lays next to him*
