buddies like this are priceless. But If I had a buddy like this? I'd return the favor. Us men need to take care of each other. Men don't get enough touch time. and that fucks up our mental health. I wouldn't give him just a blowjob. I'd give him a massage too. And I wouldn't avoid his butt. That's an important area for men.
Wish I had a buddy that understands my ongoing desire and need to give him blowjobs... I'd suck his dick three times a day ..7 days a week... and promise to swallow his cum EVERYTIME I sucked him off....
