My sister, who has yet to reach orgasm with her boyfriend, buys a dildo online to practice squirt. I peeked into her room and saw her practicing, it was so erotic that I started masturbating and got caught. She was surprised that my erect cock looked just like her dildo and wanted to try it. She squirted for the first time with a real cock. She then told me to cum inside her, and I experienced my first creampie.
