Lisa's coming over

I was just chatting with Lisa (no, I haven't mentioned her before, but I'll fill you in later) and I told her what I was up to today (gym, piano, accountant, evening drinks) and she said that she was going to put aside part of her afternoon to masturbate.

So I had a brainwave. "You could come over here to my place and masturbate while I'm doing my taxes, and I can watch you out of the corner of my eye."

She thought that was a great idea and said that in that case, she'd bring some toys with her. More later..
