B x Caring! Motherly! Reader

You and Tia (Newtale (y/n)) were sitting on the couch with B, er, you were sitting on the couch. Tia was laying down like a cat with her head on your lap. Her cat hoodie ears were perked down as her bone tail swayed off the couch.

"B," B turned to you as you smiled shyly, "I, uh, I can't get up." You said nervously. B nodded before he stretched his hand over and tapped Tia's head twice. Tia opened her eyes, blinked twice, and sat up before yawning like a cat. "Morning Tia." B said with a chuckle.

"Mornin' dad." Tia replied as she stretched her arms. "Are you feeling ok Tia? You've been napping a lot recently." You said with concern as you placed your hand gently on Tia's shoulder. "I'm ok. I just been having trouble sleeping." Tia said as she smiled tiredly.

B could tell you were concerned before you had Tia lay down against you again. "Then you get some rest." You said before Tia closed her eyes and drifted to sleep. You ran your fingers through her dirty blond ghost hair as B smiled.

"(Y/n)," you turned to B to see him smiling with some green on his cheek bones, "thank you." You tilted your head as you laid your hand on Tia's shoulder as she softly snored. "What are you talking about B?" You asked. "Thank you for acting as Tia's mother, she hasn't had the best past." B explained happily.

"(Y/n)... would be... a great... momma..." Tia said in her sleep as you blushed lightly. B heard you nervously chuckle before he kissed your cheek. You flinched as your blush grew and deepened. "Tia is right." B admitted before you smiled.

"Heh. Thanks B."

"You're welcome (y/n)."
