Stepfather fucks me! Am I pregnant now?

It was actually a normal Saturday evening. I wanted to go out with my girls and was getting ready in the bathroom when my stepfather suddenly stood at the door and glared at me from top to bottom again! How hypocritical! He must have really liked my outfit and started fingering me straight away. If mum only knew! I didn't really know how to get out of this situation and of course I was horny again anyway. It was really appealing to fuck my stepfather while mum wasn't at home. But can't he be careful? He lost the condom in my pussy and squirted all over me! Is he crazy? Am I pregnant now?
