I massage my stepsister's back and she suggests I use lubricant on my penis for anal sex

My stepsister came over for a relaxing massage, but she also suggested some fun. I indulged, stroking my cock with lubricant, preparing for our passionate anal encounter.

I was chilling at my place when my stepsister came over to get a massage. After a bit of necking, she suggested that I could use some lubricant on my dick for a bit of anal action. I obliged, and she got down on her knees to give me a handjob. But as soon as I started to fuck her tight ass, I realized that this wasn't my stepsister. My heart sank as I realized that I had been about to fuck a total stranger. I quickly pulled out and apologized, but she didn't seem too bothered by it. In fact, she even seemed to enjoy the whole thing. I tried to make up for my mistake by giving her a nice massage, and she certainly seemed to appreciate it. It turns out that this girl is quite the passionate lover, and I can't wait to see her again.
