Soft lovemaking with a pregnant wife

I'm a married man with a beautiful bride who's currently pregnant. We've been trying to spice things up in the bedroom, but it's not always easy when you're tired from work and dealing with a growing belly. Lately, we've been relying on my buddy to help us out. He's got a bit more energy than I do these days. So, the other day, my wife and I were lounging on the couch when she started feeling a bit frisky. I had to step away for a bit, so I let my friend step in to help her out. He's got a pretty good technique when it comes to getting a woman aroused. He started off with some gentle fingering, then moved on to some soft licking and muff diving. It was pretty hot watching them get down and dirty.
