Carefully

"Do you want to put it in yourself?" You ask.

"Eh, maybe you can do it."

"Okay then. What do you say if it begins to hurt?"

"Fruit Loops."

"Good girl. Now strip."

Adela proceeds to strip down. As soon as she's naked, she lays down on your bed, ready for you and her new toy. You begin by using your finger to ease her rear entrance, spreading lube around it. Next, you slather the butt plug with lube. Certain that your toy is ready, you ask Adela "You ready?"

"Yes Sir."

Without further ado, you press the tip against Adela's ass, causing her to gasp. You do your best to ease the toy inside of her. As it sinks deeper Adela coos "Mhmm... That's nice Sir."

You continue to ease the toy further into Adela's asshole, to which she moans. Her body seems to shuffle with slight discomfort, but the smile forming on her face tells you she's enjoying this. As your little submissive moans, you feel your cock strain against your pants. You can tell by the resistance her ass is giving the toy, that it'd squeeze on your shaft perfectly. Eventually, the entire length of the toy is inside of Adela.

"Phew... Is that all of it?" She asks.

"Yeah. You okay?"

"Yep. It feels incredible."

"Good to hear. You've been such a good girl."

"Thank you Sir."

"Seeing as you've been such a good girl, I'll let you chose what we do next."
