--------------------------------------------------------------------------------------------------------------------------------
You and Eric couldn't believe it when Ariel told you two that she was pregnant, you three were so excited and couldn't wait to meet your future son/daughter. For the past three months, you two had taken care of her making sure that she didn't strain herself and just focused on making sure her and the baby were happy and healthy. If she had a craving, one of you two always got it no matter how ridiculous, back or feet hurting, you two were there attending to her every need, and don't get her started on when you two spoke to the baby, she swore it was the cutest thing, she saw.
You had gone out to the ocean to give her father an update on how she was doing with the pregnancy since you were still able to get in the water and into the kingdom. You were returning to shore when you saw Eric standing there in a white button smiling as you came to shore, you had to admit that ever since Ariel had gotten pregnant seeing him as father made you realize that you wanted to have a kid too.
"To what do I owe the pleasure of having you greet me at the shore?" You asked him as you walked on land.
"I was missing you, my love, I've been spending so much time with Ariel lately, that I've been neglecting my favorite hybrid." He said kissing you.
"I've missed you too my love, but I know Ariel is our main focus right now but I won't complain if you wanna show me a little attention." You said as you kissed him.
Soon enough the gifts that King Triton had given to give to Ariel for the baby, were soon forgotten as you two were tangled up in each other in the sand. You two lay there catching your breaths when Eric noticed your far-off start meaning something was on your mind.
"What's going on in that pretty head of yours?" He asked looking at you.
"Seeing you this past month with Ariel and our kid has made me realize how much I want to have a kid with you, but given my nature, I don't think it would be possible." You said sadly as Eric's heart broke hearing how sad you sounded.
"Hey hey look at me, you would be a wonderful mother, and no matter if our child turns out to be a human, mermaid, or hybrid like its mother, it would be the greatest gift ever. I know I didn't plan on Ariel getting pregnant so soon but I am willing to keep trying to see if it's possible as well for us, if you are." He said squeezing your hand.
"I would like that a lot. I love you Eric." You said placing a kiss on his lips.
"I love you, my little mermaid." He said smiling at you.
It was nearly three weeks later, Ariel was finally showing, and by goodness did she have this beautiful glow about her. You three were currently eating breakfast and talking about your plans for that day when you felt yourself getting sick.
"Y/N!" Ariel called out seeing you dart for the nearest trash can.
You were puking your brains out when you felt Eric grab your hair and rub your back, as you finished puking. One of the maids handed you a napkin to wipe your mouth as you stood back up and suddenly felt lightheaded.
"Here take a seat my y/n." Eric said helping you into a chair.
"Can one of you go get the doctor please and thank you?" Eric asked one of the maids.
He sat with you making sure you ate some crackers and drank some water while they waited for the doctor to come, and stepped out to check on Ariel who was looking at you concerned.
"I need about twenty minutes to do some tests on her." The doctor said as Eric nodded his head leading Ariel to the dining table.
"Y/n what is it?" They both asked as you walked back into the dining room.
"I'm...I'm pregnant." You said in disbelief as your two lovers looked at you.
"You are? That's amazing! How far along are you?" Ariel asked wrapping her arms around you.
"The doctor suspected maybe 4-6 weeks, which means our babies will be born almost four months apart." You smiled at her.
"This is so wonderful!" She said smiling at you as Eric walked over.
"She's right this is such amazing news, sweetheart, I'm happy right now." He said wrapping his arms around you and spinning you around.
"Eric!" You said giggling as he put you down.
"I'm sorry and just so you know if they are human, mermaid, or hybrid like you we will love them unconditionally." He said smiling at you.
