After my first year of college I decided to spend the summer at my grandma's house. She live closer to my college town then any other family and my parents were on holiday in Europe anyways. My grandmother lived in a very small town so I didn't see any sense in driving down. My car would just end up sitting in the garage the whole time.
So after my last final I took the first flight to my grandma's and then took a taxi to her house. When I arrived I noticed that my grandma didn't have a car either. I remember hearing my parents say that most people in the town just use bikes to get around.
My grandmother and I had a blast for the first several weeks of summer. She loved having the extra company around. It had been a while since grandpa passed and my grandmother always loved when we came to visit. She taught me a few of her famous recipes. I helped her with a her gardening and fixing the odd fence or window. I also figured out that my grandma and I both have a dirty sense of humor.
Now that it was August our time was coming to a close and it felt like we had done just about everything the little town had to offer. The only thing we had left to do was attend the annual baseball game played by locals.
I was actually excited to go this year and was half way out the door when I heard a voice from behind me.
"Where are you off too honey?" My grandmother had just walked in the room and was headed my way.
"I'm going to the baseball game, you wanna come with?" I saw her eyes light up as I finished my invitation. She simply smiled and nodded her head several times.
"I'd love to, I'll make us some snacks the prices for concessions at the game are outrageous." She said as she ran back to the kitchen.
After a few minutes my grandma returned with a giant picnic basket full of sandwiches, chips and drinks. I opened the door for her as we made our way outside. As we reached the car port I stopped in my tracks.
"Nana, That basket is to big you'll tire yourself out carrying it the whole way. Let me carry it for you." She looked back at me with a sweet smile.
"Oh sweet heart were going to take the bikes it's faster." She finished talking and then moved to a medium size shed at the other end of the complex. She set the basket down and unlocked the door. Inside were two heavily customized bikes that my grandma and grandpa had use to travel around town.
As we pulled the bikes out and got ready to head out my grandmother kicked her bike in disappointment.
"I forgot the chain on my bike is broken." She said in a defeated tone. She looked up at me and pointed to my bike.
"We can just take your grandfather's bike. There is plenty of room for both of us and I can just hold the basket on the back." As she started to head towards me I looked down at the bike I was now on.
My grandmother was right about the room aspect of the bike. My grandfather had installed a huge seat in place of the standard one. I had my doubts but, as my grandmother climbed on I figured it was worth a shot.
My grandmother wrapped one arm around my waist and used the other to steady the large basket on the back of the bike. A few seconds later we were off and pedaling down the bike path.
After only a few miles on the semi-bumpy path I could feel something poking me in the back. It took me a while to figure out what it was as we rode down the path. Once I figured out what it was I was in disbelief. It felt like my grandmothers tits were poking me in the back.
Several questions were racing through my mind. Why was my grandmother not wearing a bra? Why was my grandmother getting hard nipples on the bike ride to the baseball game? I tried to justify it in my head as bumpy roads and that it was hot outside.
Only a few more minutes passed before my grandma poked me in the side.
"Honey I don't think this is going to work. Maybe I can ride on the front of the seat and balance the basket on the handle bars." She said.
A wave of panic washed over me as she suggested the seat switch. I was just now realizing that my grandma's tits rubbing on my back had made me semi hard. I tried coming up with logical sounding reasons why that wouldn't work but, she wasn't having any of it. My grandmother ultimately won the argument and we stopped to switch our seating up.
My grandmother seemed pleased with the new arrangement as she smiled back at me. I tried to create as much space between my crotch and my grandma as possible.
After a few more miles on the bumpy trail my grandma's ass had moved all the way back on the seat. With the next big bump we hit her ass bumped into my shorts covered cock.
"I think there is a piece of the seat hitting me Richard would you see what it is?" She didn't look back at me just continued to hold the basket in place. I tried to play it off like it wasn't a big deal.
"I don't know what it was nana let me reposition the seat that could help." I grabbed grandma by the hips and pushed her up the seat a bit while pushing myself back a bit.
After a few more minutes we were in the same position again with her ass hitting my now rock hard cock. Grandma rubbed up against it one more time as if in disbelief. There was nothing to hide behind now I had to come clean.
