I can't help myself (my slutty friend Nikki)

My friend Nikki (who lets me fuck her once or twice a week) is quite a little slut. She likes to tease me by sending me videos of her fucking other random guys she picked up. In the videos she sends, she is always fucking the guy without a condom. So, I know should wear a rubber when I fuck her but I just can't help myself... I always want to fuck her without a condom when I can. I just love shooting my cum right in her pussy.
