So it isn't very long but very hot. A couple of years ago my cousins and I were having a sleepover at my house. This is due to my grand parents not having enough room and they live at the other end of the country so they would often sleep over, so we went to go to bed after a long day of messing about in the garden and we only had one blow up bed so my younger cousin (aged 15 at the time) slept on that bed whilst my other cousin (aged 16 at the time) climbed into my double bed with me.
We are both pretty broad lads with nice bodies and we both sleep in just boxers. So this night it was about 100 degrees in my room with the three of us so I took off my boxers thinking it would help me cool down and get to sleep, which it did. I woke up at about half two to find that I had no covers on and my cousins hand around my cock slowly jerking it. I got up and grabbed the covers and said 'WTF dude!' he said, 'Sorry it looked hard so I thought I would help you out'. He had given the perfect answer so I just turned over and pulled his boxers down to his ankles and helped him out.
We soon heard my other cousin whisper what are you guys doing? We said nothing and stopped for a bit before carrying on. We threw the whole sheet off the end of the bed and held and stroked each others dicks until our cousin got up and went to turn the lights on. Before we could do anything the lights were on and me and my cousin were fully open for my other cousin to see. We let go of each others dicks and went for the covers. 'why didn't you just tell me you where jacking off' he said.' I've had this boner all night, can I join you?' 'Yeh sure we said' so we all lay against the head of my bed jacking off. We took it in turns to cum and we went to sleep all jacked next to each other. The next morning we woke up with dried cum stuck to us. We haven't done anything since but have loved that time ever since this day.
