Toriel

"So...who's Toriel?" Mako asked breaking the silence and following Frisk. "Well, I know she was once the queen of monsters but she got divorced, and when I fell down here, she was right there to guide me...she also saved me, from that dreaded creature..." Your ears perked up "Who exactly are you talking about? What creature?"  Frisk opened their mouth but was cut off as the door swung open "My child! Thank goodness you've returned- who are these beauties?!" Toriel rushed past Frisk sweeping you and Mako up in her arms. "They fell down the hole..." You blushed as Toriel pinched your cheeks "I-I wonder where all the other monsters are, except for froggits, where are they?" Mako yelled into the goat's floppy ear. Toriel said nothing for a while, then suggested pie and a bath, obviously trying to change the subject. Being tired, dirty and hungry you all decided to accept her offer.

-Timeskip-

"B-but mom!" Frisk cried, not wanting to bathe alongside you "I can't take a bath with her! We're both teenagers!" Toriel huffed, "Frisk, dear you're both girls, so it's fine" You covered your mouth and snickered. Frisk whispered "Actually, I sexually identify as Agender not A-gender." Mako, being the snarky little turd he was, stuck his hip out in a MTT-like pose, "What's wrong Frisk, afraid you'll be aroused by my sis too much?" You blushed and grabbed Frisk by their sweater, pulling them to the bathroom. "W-wait! Let's talk about thiiiis!" Frisk pleaded grabbing things so they wouldn't have to take a shower with you but to no avail.

-Very smol Timeskip, like 5 minutes-

You turned, reaching to the middle of your back, attempting to clean it, and failing. "Hey Frisk, could you...like...wash my back?" Frisk was currently sitting in the corner, wallowing "S-sure whatever" You smiled, sighing as your back was cleaned, suprisingly well, by Frisk. "Thanks bud, I'll do you too..." After awhile of washing and rinsing, you stepped out of the washroom, a towel over your waist and head. Frisk came out too, wearing boxers (both girls and guys can wear them so eh why not) and their sweater "Ahh" you sighed, "this is the life" You noticed Frisk, not staring at your eyes, but rather a very noticeable, uncovered part of your body. "O-oi! My eyes are up here y'know!" You covered your chest and ran straight to the room you and Mako were sharing. After picking out a pair of boy shorts and a white tee, you sat down to mess with the Tv remote that was on the nightstand. 

-knock-
   You turned towards the door, standing to open it, "Yes?" Mako smiled "Hey sis, Mum said that if you want something to eat, you'd better get some pie," You chuckled, thinking of goat mom, "Well, guess I'm not eating tonight, I've gotta catch some Z's," Mako sighed, and walked up the stairs, no doubt going to eat some pie, you closed the door and laid down, falling asleep before you know it.
