Ryleigh Sullivan has no plans on following through with the next Best Friends Challenge, especially when that challenge includes babies, bottles and back rubs. Well, she'd take the back rubs, but she may be down a husband if Martin doesn't get it through his sexy head that she's not ready to be a mother. The more he talks about it, the more she realizes they may never see eye to eye on parenthood. It's never fun when sex becomes a game of what if. Especially when their marriage has been the best kind of love so far.
