Only One String Attached

Part 3

"Katsuki, would you like to join us today?" Kanami warmly offered.

"I really do need to go, unfortunately. Maybe another time." Katsuki said, forcing a small grin on his face. "It was very nice to meet you both." He said, before striding out of the apartment. Eijiro watched him leave, worry tugging at the back of his mind.

"Alright, Ei. Go get ready. We got stuff to do today." Hotaru chided teasingly, the strange tension seeming to follow Katsuki out the door. Eijiro nodded, and headed to his room, getting ready for the day. As he started pulling clothes out, his phone buzzed, capturing his attention.

Katsuki: text me when they leave. I'm taking you out tonight.

Eijiro's worries that his moms had scared him off subsided a little bit.

Eijiro: KK 👌😁😁 Where are we going? Do I need to dress up?

K: Nowhere too fancy. Just don't look like a fucking slob.

E: you got it 👍🤜🤛

Eijiro grinned at his phone before getting ready. He continued pulling out his clothes, adjusting the outfit a little bit so it was appropriate to go straight to dinner. As he opened his top drawer to pull out a pair of clean briefs, his eye caught on something shoved in the back corner. He paused for a second before pulling them out, the red lacy panties unfurling from the crumpled pile they were in. He pulled them on to see how they fit, if they did, maybe he could surprise Katsuki tonight.

He had bought this particular pair of panties after Hiroto had left, not for any reason other than the thought of wearing them had made him feel sexy. The shade of the thin red material matched his dyed hair almost perfectly, and that had only made them more appealing to him. But that was months ago now, and his stomach was getting rounder as his pup grew inside him. They still fit him, but the fabric was stretched across the slight curve, distorting the delicate design, and causing the material to roll down on itself.

He sighed, self conscious thoughts taking center stage. There was no way he could wear these today, they don't fit right, and Katsuki definitely wouldn't find them sexy. He hooked his thumb on the fabric to change them out, but there was a banging on his door.

"Eijiro, c'mon honey. We only have a few hours!" His mom called through the door.

"Okay!" He responded before sighing. In reality, he had time to change underwear, but he'd just change them out when they got back and before Katsuki picked him up. He pulled on his jeans, and shirt, grabbing one of his other shirts to layer with, before running out to the living room.

"Finally! You take longer than Ma to get ready." Kanami joked, glancing over at her partner who pursed her lips to hold back an amused smirk.

As soon as his shoes were on, they were out the door. They had planned a day out of taking him to see the new Crimson Riot movie, lunch, and then grocery shopping, since he didn't have a vehicle of his own and they didn't want him having to carry all the groceries himself.

"Call us if you need anything, okay?" Kanami fussed after they unloaded the absurd amount of groceries they had bought him. "And give Katsuki our number, in case anything goes wrong. Then he can contact us."

"I will." Eijiro reassured her. "Thanks for today."

"Of course, honey." Hotaru smiled. "We love you."

"Yeah we do. So, so much." Kanami gushed, pressing a hand to his cheek. Even though he was an adult, and definitely didn't need his mom's to scent him anymore, he nuzzled against the small gland on her wrist.
