'If it ain't broke don't fix it' You think to yourself. "Are there any other options, my lady?" You ask, trying to barter your way out of this.
"I would have said so if there were. It's okay, I'll be gentle." Sansa said in a sweet voice trying to guilt you into agreeing.
"I guess that I'll be your cushion... But it seems more likely to me that this is a reward for you." You said.
Sansa smiled and said "I guess that I'll let you pick your reward next time... but you already seemed to have agreed to this. And I don't suppose that it'll be that bad for you. I think you might quite enjoy yourself." Sansa sat up, reached forward and grabbed you. "I have to write a letter, so I don't think that there is a better time to... sit down and write it." Sansa said, giggling at the last part.
Sansa stood up off of her bed and walked over to her desk. She pulled back her chair and gently set you down in the center. "Now just relax and enjoy yourself, my little friend." Sansa said, as she moved and stood over the chair. An idea popped into her head, she giggled, and then hiked up her skirt above her waist exposing her panties, and began to lower her panty-clad ass on top of you. You were surprised by this, and laid down flat on the chair face up rather than be pushed down and be stuck in a potentially uncomfortable position.
Sansa sat down square on top of you, pulled the chair into the desk, and adjusted her butt on top of you to get comfortable. You found yourself yet again pinned beneath Sansa's enormous sexy ass. Sansa grabbed her quill and began scribbling out her letter. She occasionally wiggled her hips around, adjusted all of her weight to the center of her backside, or even used her armrest for support and gently bounced her ass on top of you for a bit. Sansa had never taken so long to write one letter, but it didn't particularly bother her.
Once Sansa was finished she pushed her chair back and stood up. She looked back to the seat of the chair and was shocked that you weren't there. She quickly realized what had happened and her face flushed with color. Sansa squeezed her massive butt cheeks together and felt you firmly wedged between them. "Can't let this opportunity go unused" Sansa said to herself. She walked over to her bed, and adjusted her skirt to sit on the bed like how she sat on her desk chair.
You couldn't believe that you were stuck between Sansa's ass cheeks, not that you could complain though, considering how comfortable that it was. you felt the pressure around you recede as she went to sit back down on her bed. When her ass was a few inched above the bed her cheeks were spread and you fell to the bed only to be enveloped be her ass again a moment later. Once she had sat down Sansa began to wiggled her butt left and right smothering you with her pale, soft ass flesh. She then began to move her hips around in random directions all over you. Sansa's soft ass was rubbing all over you.
You don't know how long this was going on, but it didn't matter because you were in heaven the whole time. You never wanted it to end, but it inevitably had. Sansa stood up off of the edge of her bed and pulled her dress back down to cover her... assets. You sat up, a bit dazed from all of the smothering. Sansa knelt down next to her bed and giggled when she saw your current state. "I thought that you said I would enjoy this more than you would, not that I didn't."
"Well I guess I was wrong." You said, admiring Sansa's beautiful blue eyes.
Sansa smiled and replied...
