This story takes place almost six months after the story in Part 3. My wife and I are home.
My wife and I had started trying for a baby. We had married a little bit later in life and perhaps left starting a family a little later in life too. Unlike some of our friends, conception for us wasn't coming easily.
My wife went after the advice of a specialist Doctor. IVF was discussed, obviously. The initial advice however was that sometimes couples put too much pressure on themselves to conceive that it can work against them. Often stories are told about couples that finally give up trying for a baby and suddenly have success.
The suggestion from the Doctor was to take a holiday, try to relax, get away from work. Try to spice things up a bit.
In an effort to tick all four boxes at once my wife announced to me that night that, "We're going to my mothers' place".
My mother-in-law knew we were trying to have a baby and, I believe, knew of our difficulties. She was happy for us to visit.
We left the next morning and arrived at about lunch time. After a brief lunch my wife said that she was going to a day spa -- by herself -- as part of her relaxing process. As I had done previously, I went for a run on the treadmill.
I was a typical sweaty mess afterwards. My mother-in-law was in the lounge room on her phone (Facebook, no doubt) but was keen to have a chat. I kept the discussion brief and towelled off and started to strip off in front of her. My mother-in-law took it all in her stride and I suspect in the context of what we had previously done together, it was "small change". Stripped down to nothing, I went off for a shower.
Under the pretence of not having a towel (I didn't, but I knew where they were kept), I called out to my mother-in-law for one. She brought one in and sat on the edge of the bath as I finished up, stepped out and received the towel to dry off. She sat there making small talk and taking my nakedness all in. No doubt I was bringing back memories of our last visit.
My wife came back a few hours later. She had been away longer than expected.
In the early evening, my wife was quite open with her mother about trying for a baby and the need to relax, spice things up and try new things. (I don't remember the Doctor mentioning to try new things but I guess it was in keeping with the directive).
She asked me to stand up and take my jeans off. I was happy to. She reached into my boxer shorts and extracted my penis. She explained to all of us that "this one" needed to perform over the next couple of days. My wife didn't often personify my penis, but I liked it when she did.
She carried on that whenever I seemed to be "ready for action" that she would make herself available. My cock was responding well to this plan, as its stiffness and length attested to.
"But ...", my wife continued. "The next couple of days the focus needed to be on my pussy". I loved it when my wife talked dirty. Doing it in front of her mother added an extra dimension.
After making this further proclamation, she also stood up. She took down her pants and underwear to reveal to the room her freshly waxed pussy. My wife had trimmed in the past but this was the first time she had a wax down there. This explained why she had been away longer than expected.
I sat down again, in order to admire it. "Wow, that's great", was all I could say. I was honestly lost for greater eloquence. Her mother made some positive comments and my wife seemed very pleased with the responses all round.
I reached out and felt the smoothness of her pussy. It really was amazing.
"Do you want to give it a test drive?" my wife asked me. My cock was ready to go so my answer seemed pretty clear. We hurried off to the bedroom and I came inside her pussy very quickly.
The next day the weather had turned and it was raining. I got up and had a coffee. My mother-in-law was already up. I noticed the house felt warmer than usual. My wife got up soon after and I went off for a shower.
Just as I was finishing up my shower, my wife suggested to me that I could hang around the house naked for a bit. I was happy to do so. I had done it before and it felt nice. My wife then jumped into the shower herself.
About 15 minutes later I was astonished (but pleased) to see my wife join me also stark naked. She explained that she wanted to continue to show off her "girl bits" to us.
Well, that was an interesting morning spent inside, I can tell you. Every time I looked up, I was greeted with the sight of my wife's bum, boobs or smooth pussy. It didn't take me long until I was sporting a permanent erection, which brought forth looks and comments from the ladies.
At one point, I sat on one of the tall stools at the breakfast bench and my cock stood up perfectly vertical and above the bench top for all to see. My wife reached out and gave it a few nice touches for good measure.
The rest of the morning proceeded with my wife touching my dick or me fondling my wife's arse, boobs or gently touching and admiring her pussy.
I think all the attention I was giving to her pussy had come to her notice as she lingered in the lounge room in front of me after bringing me another coffee and adopted a wider stance with her legs. This allowed me to allow me to look closely at her vulva and split apart her pussy lips for further inspection.
My mother-in-law was enjoying our interactions. She herself would give my cock some nice, teasing touches. I would pause at whatever I was doing to let her have her play. Most of the time, she gave my balls a cradle and a feel, which was also nice.
Later in the morning while my wife and her mother were watching TV, I walked in -- my on-going erection leading the way. My wife reached out to me, took a hold of my cock, brought it to her mouth and proceeded to suck on it. With all that had been going on, I found myself a mere 20 seconds or so in on the verge of cumming. I said this to my wife and, sensing the urgency in my voice, stopped what she was doing. She laid down in front of me and her mother on the carpet and opened her legs widely.
Without hesitation, I adopted the position on top of her and pushed my cock inside her smooth pussy. She was very moist and I went in easily. She wrapped her legs around me and with less than a dozen meaningful thrusts, I came hard inside her.
My mother-in-law, feeling very much part of the process, said, "Well done, my darlings!"
We were all quite done and spent for the rest of the afternoon. My mother-in-law, I noticed, turned down the heating in the house as my wife and I put clothes back on again.
