After taking some time to get used to the feeling, I cautiously got closer until my groin area had a full hold of her ass. I felt her soft ass compres...s as my dick pressed into it. After a while, my hips started to move almost involuntarily to make my hard dick thrust hump her ass through our night garments. I could see our bodies were moving as one from my heaving and grinding of her ass from below and the side. This turned me on more and more until after a few intense hits, I felt the rhythmic. I fondled the guys low hanging balls before putting my mouth on his huge light skinned cock. I loved the huge blue vein running up the bottom. I began sucking it and within seconds it was this huge, proud erection that had to be at least 10 inches long! I first sucked the head before my traditional bob and I needed to get the shaft lubed up with my saliva before proving Susan wrong. The guy trembled and enjoyed my mouth sucking his dick. That's when I went half way down, paused, then engulfed. "Steph, it won't take me more than an hour, maybe two! I've installed all of those in our kitchen at home, and even for some of our other friends. There isn't much 'real' installation, mostly putting in plugs and hooking up a couple hoses," I explained to her.Stephanie's face lit up."That would be wonderful, Mark. OK, if you don't mind, I'll call you tomorrow" and she left for home.The following day was Valentine's Day, and for the first time in our marriage, there were some things not. She dressed somewhat unconventionally, also. I would almost call it dorky or else not intentional sexual or even feminine. Occasionally, though, for work or some other function, her rarely seen tight fitting outfits only added to my conviction of her flawless body. She often walks her to little dogs in sweats, but again, occasionally I'll be lucky enough to spot her eatable behind in yoga or stretch pants, after which I regularly masturbated. I should note here that the admiration was.
