Last Saturday it was about 100 degrees, so my friend John and I decided to go to a lake about 30 minutes away to hang out. We spent most of day there, and I got a pretty bad sunburn. We went back to his house about 7:00, and his parents had gone out for the night. I was complaining about my sunburn, so John found some lotion and stood behind me and spread it on my shoulders and back. It felt really good, and cooling. He reached around and spread some on my chest and stomach, and when he rubbed over my nipples it felt really really good, and I could feel my dick start to get hard. He did the back of my legs, and when his hand was on my inner thigh, his forearm brushed against my crotch and boner.
John didn't say anything, and then he did it again, but held his arm against it, and started rubbing back and forth. He then groped me with his hand, rubbing up and down my boner through my trunks. Neither of us said anything. He reached up, and untied my trunks, and slid his hand inside. He grabbed my dick in his slippery hand, and ran it up and down. I could feel his bare chest against my back, and his hard dick against my ass. I still didn't say anything, just leaned my weight back into his chest. He pushed my trunks down, and started to pump me. He wrapped his other arm around my waist, and starting rubbing my stomach and chest while he jerked me. It sent me over the top, and I busted my nut all over the floor in the best orgasm I had ever felt. John kept jerking me, but my dick was so sensitive I had to pull his hand away. I turned around, and undid his trunks and slid them down and his dick popped up and slapped his stomach. I turned him around and starting jerking him off the same he had done me. He came really fast, his cum just oozed out though. He didn't shoot like me.
The whole time we never said a word to each other. After we had both cummed, he said, 'that was hot' and I agreed.
I have jerked off every day this week replaying it in my head. Tomorrow were gonna go back to the lake, so I can't wait to ask him to put some cream on my back again.
