A loving mother, for a change

We open the door to find Rias in the kitchen connected to the living room, she appears to have made light snacks for us and turns to greet us with them. "Oh, you're home! I made snacks, help yourself." Wait 'yourself'? Oh, wait, doy. Robots. I enjoy the snacks and the larger house, but I never really needed much space. She so how knows my favorite foods and prepares them perfectly. "Honey, I was thinking we could have a family game night to bond. What do you think?"

"I didn't even know we had board games, but I'm fine with that."

"I would prefer a more personal method for bonding, but there's nothing wrong with that."

"Whatever."

"Okay, I've already chosen our first game." Rias seems really enthusiastic about this. We spend the night playing old-fashioned games I didn't even know they still made. I don't know how rolling dice and moving pieces helps bond, but it does pass time. When I get ready to go to bed, Rias stops me.

"Y/N, where are you going?"

"To bed."

"Not in there you're not. I couldn't find anyone that could fix your window today, and you can't sleep next to a broken window. That's just asking to catch a cold!" I hadn't thought of that...

"Alright, I'll sleep on the couch."

"No. You're sleeping with me tonight." I feel a blush rise in my cheeks. A maternal, bustier version of Rias just asked me to sleep with her. I know with her programming, she doesn't mean sex, but come on! You know how any teenage boy would react to that, and if she's supposed to act like a mom...

"Do I have to?" Akeno brings forth an alternate solution.

"Well, if you don't want her, I'd love to share a bed with you." Oh, yeah, she's like that...She'd probably react better than Rias, but knowing what she's into...

"Nope, Rias is good!" Rias looks satisfied at the outcome while Akeno pouts.

"Oh, poo, why does he always do this?" I've literally only done it twice. Once if you don't count the one at the other apartment.

"You need to stop being so ecchi, Akeno-neesan." In her room, Rias is in a nightgown that...oh what'd I expect!? It perfectly highlights her bigger tits and wider hips, on top of being one step from translucent. As she sits down, I feel that same blush rise in my face. At least she isn't naked. We pull the cover over ourselves and I turn over to help sleep and avoid temptation. Temptation comes right back though, when I feel two very large somethings press into my back. She wraps her arms around me in a sideways hug and whispers to me.

"Good night, son."

"Good night."
