How long do you last?

Normally, I'd say 15 - 20 mins..... thats good enough for her....

For when she is ready, she tells me where she wants my cum, and its almost like a command.... otherwise I'd prob continue..

However, there are always the moments of 1-2 mins MAX in the morning right before her sister "routinely" comes in to borrow her heels for the days work...

Its always the same time of morning, and there have been a few close calls...
and one really embarrassing moment of getting walked in at the time of dumping my load on her......
