Grandma's House

Every Easter, my entire family (about 40) travels to my Grandma's house to celebrate for a week of food and fun. During our stay, space is limited as well as bathroom/shower time. This, combined with the constant onslaught of little cousins, leaves no time for masturbation.

An avid masturbator, a week without leaves me crazy for a wank. To make matters worse, on the way home my father decided to take the scenic route via the ferry, which meant even longer till I could get home and wank.

We left Grandma's and headed down the freeway, after a few hours we hit our turn off to the ferry, little did I know it was a dirt road. Our car sits very low as it's a family vehicle and the vibrations from the road were violent and stimulating.

I'm sure I don't have to tell you that within minutes my 8-incher was pressing hard against my jeans. MY GOD I WAS HORNY! I couldn't stand it-my cock throbbed and ached! So I had to relieve it, problem was my sister was sitting next to me and mum and dad in the front. What to do?

Luckily, my sister fell asleep within the next few minutes and so did my mum; dad was focused on the road so I knew this was my opportunity.

I grabbed the picnic rug from the back, claiming that 'I was cold' and threw it over my crotch. I had to be careful not to move too much, so I popped my slick cock head out of my fly and began rubbing it for all it was worth.

The pleasure was intense! Harder and harder, and faster and faster I rubbed my cock. Precum was flowing out. I knew it wouldn't be long before I came so I crammed my cock into my jocks and rubbed my head through them. I could not get cum anywhere obviously.

I rubbed it so hard for about 15 minutes till this violent surge erupted from my cock. I dug my toes into the floor to try to stop myself from moving and I felt my underwear filling up with warm, sticky cum.

I left my cock to marinate in this delicious package for the rest of the trip. I fell asleep and awoke to mum shaking me.

As I left the car I noticed a huge wet spot on my jeans-it had soaked through! So, I wrapped the blanket around me and ran straight upstairs claiming I had to pee! I got changed and kept the jocks wet to wank into later.

My god, the best cumshot I'd ever had!!

Or was it...
