Petite girlfriend prepares for anal penetration with butt plug

My girlfriend is the sweetest and most adorable girl you could ever meet. She's petite, skinny, and always eager to please. One day, I surprised her with a little gift - a butt plug to prepare her ass for the upcoming anal penetration. She was excited and eager to try it out. I slowly inserted the plug into her tight asshole, watching as her hole stretched and gaped to accommodate the toy. It was a sight to behold. The sight of the plug in her ass made my cock harden, and I couldn't resist fucking her right there on our couch. The pleasure was intense, and we both moaned in ecstasy as I pounded her tight asshole. The experience was mind-blowing, and we both fell asleep exhausted but satisfied.
