"B-Butt cushion?" You echo to Mitsuri, as she giggled and chuckled. She was so beautiful when she does anything, and she was showing you so much kindness and affection, you were considering being flattened.
"Follow me cutie and I'll explain." She beckoned you with her finger and walked, as you now move and chase after the giantess. Following her and running after her ankles. She was walking casually and normally, so she moved through her home much faster than you did. You were running as fast as you can!
Mitsuri got to where she wanted, as she turned her head and saw you chasing into the room.
"So cute~" She remarked, as you ran in and got right in front.
"S-Sorry... I took so long?"
"You don't have to be, but next time if you want to move fast hihi... you can jump on my foot~" That was a good idea, as Mitsuri was in such a good mood. "See that seat over there?"
Honestly less of a seat, and more of a cushion sat in the middle of the room in front of a table. granted it was the Japanese style, so it made sense.
"Y-Yeah..."
"You are going to lay down there, and cushion my rear. I won't try to hurt you, I just want to feel you under me." You look at her butt once again, as she turned around and actually showed it to you. Pushing her rear closer to you as she smiled.
"I think you would like to be under here, wouldn't you?" She teased, winking at you as you look up to her.
"I-I don't think that's really what a personal servant does Mitsuri... but I'll happily do that." How can you not, you were about to be under the butt of a giant beautiful girl. Sounds too good to say no to.
"Aww, you will? You are the best Demon in all of Japan! Although there isn't much competition for you~" She winked playfully as you continue your journey. Moving over and climbing the cushion, before getting to the middle.
She was standing over you as you lay on your stomach.
"No silly, turn around. I want your face against my butt." The way Mitsuri put it, you might want the exact same. You turn around and get ready, as you stare up at her smile.
Mitsuri turned herself around, showing her rear in her black skirt. She's going to enjoy this very much, and she can tell you will as well. If this is good, then you can be under her rear in important meetings, or whenever she is busy doing something else. Maybe you can even be in between her cheeks at points! It all depends on how good this was.
"Here I come down cutie~" Mitsuri bent her large rear down, and it was coming for you. All you can do is take it, and take it you will happily!
For Mitsuri, it was simple as sitting down on a cushion, and noticing that something was there. For you, it was welcoming an amazing ass, being pressed and flattened under. It was as amazing as you thought it would be. Heavy, large butt pressing down on top of you. The cushion made it soft, as it rested on you.
The giantess continued to sit down on top of you, as she giggled.
"Okay, so far I'm liking this, you are super comfy to sit on. Although I need to test you a bit~" So the giantess did just that, rubbing her butt on top of you from side to side. Doing a small grind just to see how it will feel for you to be under her.
Her booty rubbed on top of you, just side to side motion as she was seeing what this would feel like. She enjoyed it... maybe to a degree where it was too much. She bit her bottom lip and continued.
For you, even though the treatment could be classified as rough, you were in love with it every second. Her butt was amazing, as amazing as her breasts were. Sure there was a skirt and her underwear over you, but you were still able to enjoy it. If only you were touching her actual butt then, you would have a boner that you could not control.
"Okay!" The giantess clapped. She stopped moving her butt on top of you and just sat normally. Holding her weight down onto you. "I think this is great! You are working out as a great seat. In fact hihi... I think all demons should be seats for pretty girls like me. Wouldn't that be great~" You don't know if she was serious or if she was just teasing, but you had a smile on your face regardless.
She moved onto her knees, as Mitsuri did want to see if you enjoyed it as much as her booty did. On her knees, she turned her head and looked down at you on the cushion.
Out of instinct, without thinking much you ask her. "Why did you stop?"
Mitsuri was a bit shocked when she heard this, before giggling. She moved and started to drop her butt back down.
"Right, sorry me... enjoy it." The fact that you clearly did, made her confident that this was going to be a daily thing. It was just so great, her little Demon Servant must really love her! Which was great for her, because Mitsuri was thinking that only made you more adorable.
You were pressed and buried under her rear, unable to move and you still enjoyed it. Living with Mitsuri? Even as her personal servant, seems like you were going to have fun with her body. She can do whatever she wants with you honestly, you will be loving it.
The giantess with a smile on her face relaxed with you under her.
A peaceful day for her, with her tiny demon under her large butt.
What happens next?
