It was the second day of the canoe trip and after being on the water all day and having a few cocktails by the crackling fire my wife decided she was going to turn in and get ready for the following day.
This left her mother and I sitting by the fire drinking and talking and as the time slipped by we soon heard my wife's low snores emanating from our tent and we both laughed and agreed she was worn out.
Her mother stated that it was almost 1:00 a.m. and said she needed to go to the bathhouse down the road and shower before turning in for the night.
I said okay and asked if she needed an escort and she stated she would be just fine and headed off down the road.
I slipped into my tent and was getting ready to slide in next to the wife when I thought I might head down to the bathhouse and see if the mother in law was the only one in there.
As I headed down the road I noticed that almost everyone in the campground was already asleep or passed out in some cases so I continued on toward my objective.
As I entered the bathhouse I could hear the shower water running and my mind reeled at the thought at sneaking in on my mother in law like this.
If she caught me here would she scream, would she be embarrassed, would she be mad, would she tell her daughter; I didn't know the answer to any of these questions but the thought of her in the stall with the hot steamy water pounding on her body was starting to excite me.
I quietly slipped into the outer disrobing area of the stall and stood there a minute to make sure she hadn't heard me and when I got enough courage I stepped up on the changing bench and stole a peek over the top and down into the stall where I saw my mother in law facing away from my direction soaping up her body.
I watched almost mesmerized as the suds and the water ran from her shoulders and down her back then across the swell of her lovely ass and disappear into her cheeks only to reappear again as it ran down her beautiful legs and into the drain on the floor.
I thought to myself how lucky that water was to be touching her all over and all at once like that and I realized I was hard as a rock and hadn't even touched myself yet.
I almost fell off the changing stool when she turned around and looked directly at me and asked if I was going to just stare all night or if I was going to wash her back for her.
I was stunned at first and a little caught off guard and when I asked her how she knew I was there she just laughed and said a woman knows.
After undressing in the changing area I slipped into the shower stall with her and she handed me her wash buff with the soap in it and turned her back to me.
I started at her neck and worked my way down going from side to side and up and down not wanting to miss a single inch of flesh.
When I got to her ass I spent quite a bit of time washing it and even running the buff all the way down between her legs across her asshole and to the bottom of her pussy.
She seemed to enjoy this because she leaned forward and jutted her ass toward me and rose onto her toes.
She suddenly turned around and asked if I was going to do the front too and I said I had watched her do the front and she replied that it felt better when I did it and that she was felling pretty dirty right now.
I again started at her neck and worked my way down her body spending plenty of time washing her tits and watching her nipples grow harder each time the buff passed over them.
I ensured that I washed her belly button out real good and this made her giggle and then I moved on to explore the rest of her body.
When I moved down to wash her legs my face was very close to her pussy and I almost buried it in her crotch with the soap and all but restrained myself.
She was not as well trimmed as my wife but I guess that vanity passes a little with age but it didn't matter to me I knew there was still the sweet spot under the hair and I was going to find it.
After washing her feet off I rose up and my dick was hard as ever and she reached out and grabbed it and said she had never seen anyone get so excited over a little soap and water.
I told her it was the skin that the soap and water was on that was so exciting and she leaned in and our lips met and our tongues twirled around each others mouths like boot scooters in a honky-tonk bar.
As we kissed she squeezed my cock hard and my hands reached back and took her ass cheeks and pulled her body into mine and our hot flesh seemed to melt together as our passion rose to the boiling point.
The hot water pounded down on us as our tongues and hands explored each others bodies until I felt I couldn't stand it anymore so I leaned her back against the wall and started to circle her tits with my tongue.
She was rubbing my head and I could hear low moans emanating from her throat as she became more excited with each passing lick.
I soon let my tongue trail its way down across her stomach to the drenched patch of hair on her pelvis and started to slowly lick through the hair and around the edges of her clit.
She pressed her pelvis out and spread her legs a little allowing me to she the beautiful pink pussy lips just below her hair.
I let my tongue explore the outer regions between her inner thigh and pussy without actually making contact with her lips and this was getting her even hotter.
On my next pass I let my tongue lightly slide right straight up her outer pussy lips without parting them and then started teasing her clit.
She was rubbing my head and squirming around so I knew she was enjoying her tongue bath and so was I.
When I moved my tongue down and parted her lips she was extremely wet and I could tell it was not from the shower water, this moisture was coming from the inside.
I let my tongue explore her from her clit to her asshole and back not giving her one second to relax or catch her breath as I licked, sucked, probed and nibbled until she thought she couldn't take anymore and she pulled me to my feet.
She said she wanted me inside of her now and that she was going to explode on my cock.
As our mouths met again she raised her right leg and wrapped it around my waist and with a little adjustment in my stance my cock was pressing against her moist lips.
I pressed my body up and forward and my cock slid easily up into my mother in law until I was buried to the balls.
