Suddenly I did

I was frightened at first when this strange guy walked into our house. It was just me and my sister alone and I went to call the cops but he told me I didn’t have to. There was something about his voice, but I just believed him. I stopped and came closer when he told me to.
He told us to strip off our clothes. It wasn’t something I ever in a million years thought I’d do but the way he said it made it seem totally normal. So my sister and I stripped naked and then he told me I needed to suck his cock. It was only after he told me that that I realized it was true. I was hungry for this guy’s cock.
So I knelt in front of him and yanked down his pants, savoring his dick before thrusting it into my mouth. He pulled my sister close and kissed her. She resisted until he told her not to and then she sighed as she melted into him, pressing her naked body against him.
The stranger’s hand grabbed my hair and moved my lips up and down his shaft. I sucked his dick as I watched my naked sister make out with him. He told me I loved the taste of his dick and suddenly I did. I sighed as I sucked him off, tongue gliding across the underside of his shaft. I never really enjoyed giving blowjobs but I loved this one. His cock was perfect in my mouth and I ran my tongue lovingly over the head, moving faster as his hand shoved me up and down his shaft until he exploded into my mouth.
He told me to swallow it all so I did, gulping down his hot cum. My poor sister didn’t get any, but the stranger assured her he would make up for that next time. Then he left without even giving us his name. I keep thinking that I still needed to suck his cock and I couldn’t wait until he returned.
