“Sorry, but no can’t do. Now stop complaining, you don’t see Lotus fuzzing about his clothing.”
Grim pointed to the laughing and smiling Lotus, the young baby bones was dress in a very cute bear onesie.
“He’s a baby! You can dress him up in a frilly dress and he won’t care! Besides…Did it have to be so girly?!”
Dark Tempest was wearing a lovely pink Lolita gothic dress with matching heels and accessories. She looked adorable, which she hated.
“Enough complaining. Your uncle Blue went to the trouble of finding something that you will like. If you do have to blame someone, blame your father. Grim showed him a picture of you in some of your older dresses.” Mass said.
Dark Tempest was now glaring at her father, Grim just gave ignore it. She wanted to give him a piece of her mind, but was distracted by Lotus’s cry for attention. She was going to comfort her brother, only for Mass to scoop him up first.
“Can you at least tell me why I have to go with you guys to visit the Swap brothers? Especially now of all times?” She tried to sound indifferent with the whole situation. Although, she was excited and afraid to finally meet her uncles for the first time in her life (excluding Fell reaper Papyrus).
“They wanted to meet their dear niece, once they found out they had one.” Mass causally said, as he feed Lotus a bottle of milk.
Tempest tried to ignore the pulsing pain in her chest. She had found it strange that her step-uncles never asked for her presences or visit her. Especially with how her parents describe them as “cheerful” and “caring”. Only to find out that she was never mention, was heart breaking.
“…If they make me go shopping for clothing, both of you will have to take care of cupcake until I reap all the souls from the big list.” She let out a false lie and grimace to hide her sadness.
“Deal!” Grim enthusiastically agreed, while Mass had a face of dread.
****************************
*Inside the Underswap brother’s home*
“HELLO DEAREST NIECE! IT IS I, YOUR UNCLE, THE MAGNIFICENT SANS! I ALSO GO BY BLUE! IT IS SO GOOD TO FINALLY MEET YOU! THERE IS SO MUCH WE HAVE TO CATCH UP ON!” Blue said while hugging the living life out of Dark Tempest.
In the background, Grim was laughing at his daughters’ dismay. Mass was entertaining Lotus with a rattle.
“Bro, she needs to breathe.” Underswap Papyrus said.
Blue looked at his adorable niece, to see that his brother was right. “I’M SORRY!” Blue then let her go. Tempest fell to the ground and started to swallow as much air as her non-existing lungs could take.
“Sorry about that, kiddo. Your uncle Blue can get a bit enthusiastic. I’m your uncle Papyrus, I also go by Stretch.” He helped her up to her feet again.
“It’s nice to meet you too, uncle Blue and uncle Stretch? And its fine.” She hoped that it came out forgiving.
There was a long awkward pause, Lotus called for his sister’s attention. Soon there was a comfortable atmosphere where everyone just talked and snacked on treats.
Dark Tempest was enjoying the small moment, even if she did not engage in any conversation. For once, she felt safe and comfortable in her parents’ presence.
“You look so cute in that dress!” Blue said, scaring Tempest to let out a small shriek. “Shame on both of you for not mentioning her sooner!” Blue scold Grim and Mass.
“Don’t blame us, you never asked if we had any kids before Lotus was born.” Grim pointed out.
“That’s no excuse, mister! Do you have any idea how much quality time we had lost?!” Blue was fuming.
“Blue, just let it go. It is somewhat our fault for not asking them if they had any other kids. Besides, now’s a perfect time to get to know her.” Stretch said.
“Your right, Brother! So Dark Tempest, tell us about yourself! Do prefer Dark or Tempest? Do you like puzzles? Do you love your dress? What’s your favorite color? How old are you? What are your hobbies? Do you have a cellphone? If you do, what’s your number? My is xxx-xxx-xxxx. Do you have a crush on someone?”
“…uh…I-I my either, but most use Tempest. I don’t like or dislike puzzles? I do like the dress, especially since it’s very comfy. I don’t really have a color preference, so…yeah. I’m fifteen… My hobbies are cooking, baking, and reading. I do have a cellphone and my number is xxx-xxx-xxxx. No, I don’t have a love interest.” She monotony responded, with a small blush on her face.
“Okay…uh, is there something we should know? Allergies, phobias, something of that nature?” Stretch tried to keep the float of the conversation going.
“I don’t have any allergies, although, I don’t like spice food much and I don’t like coconut. I don’t have any phobias... I work as a reaper, so don’t worry if I’m out too late or long…HURT CUPCAKE AND I WILL END YOU.” She said all this with a straight face, until the end.
“…Who’s Cupcake?” Blue hesitantly asked.
“Cupcake is Lotus, I just like calling him that.” Tempest said, as she took Cupcake from Mass’s hands and snuggled him.
“More like she didn’t know his name and just called him Cupcake for a month.” Mass said, while Tempest denied the claim.
“Which reminds us…” Stretch pulled a hidden rope from somewhere, which led to a sequence of events that resulted in balloons, confetti, and cheerful music being played.
“HAPPY BIRTHDAY DARK TEMPEST!” Everyone shouted.
“Whoa, I think you out did yourself this time Blue, you left her speechless.” Stretch lazily commented.
“But of course! It will be a disgrace if I did less than my best, especially for our niece’s first birthday party as a family!”
“I think you broke her.” Grim commented.
It took five minutes for her to react, by then all anyone could hear were inaudible nonsense from the cherry red girl. After that, the party began.
The birthday celebration ended a few hours ago, where everyone did enjoy themselves with games and food. The Afterdeath family took their sleeping children home and tuck them in into their bed.
“It’s cute how Tempest reacts to the simplest of gestures.” Grim commented randomly.
“…It was nice to see a side of her that was different from her hollow or sassy self.” Mass chip in.
Once they put Lotus to bed, they retired to their room.
“Grim…do you think we’re too hard on her?” Mass softly said.
“We have to be tough with her love. It’s kill or be killed in our world.” Grim replied with defeat in his voice.
“…I know. Let’s just hope that it will help her in the future.”
