I eagerly tear into the package, my heart pounding with curiosity and excitement. Inside, I find a small, discreet vibrator, its smooth surface glistening with my girlfriend's juices. She's left a note, detailing exactly how she wants me to use it - first on my throbbing cock, then deep inside my ass. The thought of her watching, of knowing she's the one controlling my pleasure, sends shivers down my spine. This is going to be a long, horny day, and I can't fucking wait.
