It's your day off and I asked you to stop by to work on a project that's due really soon. 
I answer the door and explain that I was booted out of my yoga class for wearing stockings instead of yoga pants...I just don't see what the big issue is.
I show you them and start to do my cool down stretches that I wasn't able to do in the class...but I'm getting really horny and start to rub myself....and that's when things get steamy between us... I can't help myself...I suck you off and then ride you...I don't even take my stockings off! 
Once we've both cum really hard, working on our day off doesn't seem so bad anymore.
