I invited a female friend over for drinks at home, on the condition that her boyfriend wouldn't come. Since she mentioned she likes being led by a man, I gradually increased physical contact. Soon, a light kiss didn't meet much resistance. Maybe she was secretly hoping for something like this. Checking between her legs, she was already soaking wet. With her boyfriend kept in the dark, there was no choice but to enjoy the moment. In the end, it led to unprotected creampie sex.
