Shewolf, I just had another idea. How about if I stop in and have sex with your mother in law. Then, while she's occupied, you and hubby can do your thing.
I can probably stretch things out for a couple of hours. Will that be enough time for you to accomplish your mission?
Get back to me.
Best suggestion I've seen around here in a long time.
My MIL is quite a hottie. She used to model in her 20's and 30's...
