When your bud has his hard cock balls deep in another dudes mouth and unloads not once but twice he ain't straight! Lol That being said that was hot and i jerked off to it!
Look at how high his mound is - his balls are right up near the shaft - he's super excited. That first load was pure relief - he was carrying it and he just had to get rid of that. The second, ummmm, he made you work for it. Great cocksucking technique, I'm sure he left feeling amazing, and you? So satisfied at what you did, and already ready for the next time.
