I was sitting in my office when my wife called.  She wanted to know if I could take a week off and go help her Mom with some handy man work on her small farm.  I was not real excited about it but agreed and made the arrangements at work.

Her Mom was a big girl.  Maybe 5' 5" and easily pushing 250.  Every time we would visit she was always making some kind of sexual comment, widowed for about 10 years when I met her. 

I packed my bag for a week of work and headed out on Friday morning,  7 hours later I arrived.  Barb showed me to my room and I unpacked my things.  When I came out she was busy in the kitchen, I grabbed a beer out of the fridge and sat down at the kitchen table.  So what is my honey do list I asked.  Barb grabbed a beer too and sat down.  As always she was wearing tight spandex shorts and a tank top.  She never was one to hide her rolls and huge breasts.  She went over my list, we talked small talk and decided to run into town and grab a few things. 

We stocked up on food and of course beer and headed back.  Barb made us some dinner while I walked the property looking at what was ahead of me.  When I returned we ate and talked about our plan of attack.  The forecasts was nothing but hot for the following week so I helped Barb clean up from our meal and headed off to bed. 

I woke in the morning to the smell of cooking eggs and bacon.  As I entered the kitchen to grab some coffee Barb was in her night gown which barely covered her ass and as the sun came in the window I could see her rolls and saggy big breasts.  I could only smile to myself.  We finished up our breakfast, Barb clean up and I got dressed to begin my list. 

My first task was to tie up all the blueberry bushes.  About an acres worth.  Barb had a little road side stand where she sold blueberries and other things to make ends meet.  As the day progressed and the heat built up I removed my shirt.  Now at 45 I was in decent shape from all the work I did on our horse farm.  Barb came out a few times with a glass of ice water or tea.  As I was wrapping up the last bit of bushes I ran into a bees nest in the ground and got stung at least a dozen times.  Pissed off I made my way to the house.  My legs, back and a few on my chest.  I took some benydril and Barb grabbed some kind of lotion to put on it.  As she was putting it on my back stings I could not help but notice that it was a bit more than first aid.  More like the beginning of a sexual massage.  It was more evident when she rubbed my chest and legs.  She never looked at me as I watched her.  When she was done I must admit I was getting a bit hard.  I grabbed a beer, drank it down and went out to finish up.

I wrapped up for the day, put away my tools and headed in.  When I entered Barb had a beer waiting for me and she was already into one.  I drank that one down and another before I headed off to clean up.  As I showered I started thinking about that earlier rub down I smiled, soaped up my shaved cock and masturbated.  I need to mention that my wife had gained a lot of weight and I found her very desirable but she thought otherwise and our sex life had gone south. 

I came into the kitchen with my running shorts on.  I grabbed another beer and sat down watching Barb prepare dinner.  She announced it would be about an hour as she put things in the oven and suggested she put more cream on my stings.  I agreed.

We went into the living room and Barb began  to apply her magic on my back when my cell phone rang.  My wife.  I talked with her as Barb rubbed on my back and as I did all of a sudden my cock began to grow.  There was nothing to hold it down as I only had on the shorts.  And as I talked Barb's spot treatment turned into a back massage.  I hung up, closed my eyes and said that feels awesome.  Barb continued and then reached around and began rubbing my chest.  Her breast pressed against my back.  Suddenly she stopped and began to apologize.  I told her it was fine, it felt good.  She continued and I could feel her hands tremble a bit as she did.  Finally she came around to the front of me as I sat on a stool and began rubbing the lotion on my legs where the stings were.  There were a few on my inner thigh and I opened my legs for her to get at them.  It was now no secret that I was aroused.  My cock had made a tent of my shorts.  I closed my eyes and leaned back as Barb continued.  Cautiously she moved her hands inside my shorts, I said nothing as she slowly inched closer to my hard cock.  Finally she reached pay dirt and was touching my cock.  The next thing I knew Barb had freed my cock from my shorts and was kissing the tip, I moaned a bit and she took me in her mouth.  I put my hands on the sides of her head to control the pace.  Minutes later I was cuming in her mouth.  She looked down almost shameful.  As she stood up so did I.  She started to speak and I covered her mouth.  No words, our secret and I put my arms around her and pulled her close. 

We ate dinner and made small talk, my wife called her and they talked for a bit before Barb told her we had a big day ahead of us and we were turning in soon.  We drank a few more beers, Barb was not much of a drinker so I could tell it was having an effect on her.  Barb had also been out in one of her gardens during the day and she got a little burnt.  Why dont you clean up and I will put some lotion on your sunburn I suggested.  Barb agreed and returned wearing the same night gown she had on in the morning.  I sat her down and began rubbing her shoulders and neck.  Barb had long greyish brown hair so I moved it off to the side to do my task.  Again I was getting hard, and I moved close to let her know.  She commented, your a horny one and laughted.  I moved my hands around to her front and began rubbing her chest.  Her breasts were so damn big, I have never seen or felt anything like them in my life.  As I rubbed on her nipples she threw her head back and began to moan.  I continued to play with them and suddenly she began to shudder.  Barb was cumming. 

Barb's orgasm was intense and it really made me hard.  I walked around in front of her, grabbed her hand and lead her to the couch.  I sat her down, kneeled in front of her and lifted her night gown.  She had the most gorgeous fat pussy.  I pushed her legs a part and began kissing on it.  Suddenly my cell rang, grrr, my wife.  As my wife talked her Mom's pussy was in front of me.  I continued to play with Barb's pussy as I talked and Barb had to cover her mouth to keep quiet.  Finally the conversation ended, I dropped the phone and buried my face in my mother in laws pussy. 

I worked Barb's pussy with my mouth and fingers.  I could feel her pussy begin to tense and her body begin to shudder again.  Her old pussy gushed bitter pussy juices on my face.  I moved up from her pussy and began sucking on her huge breasts.  equal time for both.  Barb lowered her hand down to her pussy and began working herself.  Again I could feel her shake and shudder and she came again and again as she refused to take her hand off her clit.  Finally exhaused, she laid back.  I moved my face to hers as her eyes were closed and stuck my tongue in her mouth kissing her deeply. 

I stood up and lead Barb into her room.  I helped her undress and removed my shorts.  I instructed her to lay down and began to kiss and massge her from head to toe.  Every inch of her body.  Barb laid there moaning and squirming as I made my way.  When I finished I lay on top of her and whispered in her ear, "I am going to fuck you",  please she responded. 

There was no doubt Barb was wet.  She pulled her legs up and I began to push my cock into her big wet pussy.  I was surprised how tight she still was.  She was warm, wet and I came quickly.  With my cock still in her she managed to work her hand between the rolls of fat to her pussy and she worked her clit until she came so hard she pushed my cock out.  Barb fell asleep in the wet spot and I next to her. 

I woke to the smell of eggs and sausage.  Not bothering to dress I entered the kitchen.  Barb was also naked.  I walked up behind her, put my hands on her hips and kissed the back of her neck.  I then whispered in her ear, you are so much better than your daughter.  Barb giggled. 

It was Sunday morning, the phone rang and guess who.  As I spoke to my wife her Mother sat across the kitchen table naked.  Her hugh saggy breasts in full view.  She asked how things were going and I responded with a big smile on my face.  "Things are going very well here, got a lot done in a short period of time."  After I hung up the phone Barb got up, came around the table, bent over and I fucked her again.

Though out the day Barb came to check on me.  Each time she did we ended up fucking.  That night after chores were done we cleaned up and sat around drinking beer, fucking, licking, sucking.  And when my wife called we made it a habit for Barb to sit on my cock while we talked.  The thought of that alone made us both so horny.

This continued for the entire week I was there.  Barb even let me fuck her in the ass which her daughter never did. 

As I packed my bag Barb stood in the doorway.  I played my bags by the front door and we sat and talked for a bit sitting next to each other.  We agreed that somehow we needed to make our secret happen more often.  I stood up, gave Barb a long and deep kiss pulling her tight against me.

When I arrived home my wife wanted to know all the details and I found myself hard pressed to recall much of the handy man crap.  As I lay in bed that night next to my wife whose body was slowly approaching the size of her mothers I attempted to make a move and got shot down once again. 

The next morning at work I called Barb.  You need to visit soon or come up with another to do list.  She laughed.  You got it she responded.
