While my brother is here, it would be wonderful if we could find the time to enjoy ourselves the way we did when we were young and ultra-horny. We stroked each others cocks as often as we could.
And we spent many terrific times with our buddies jacking and cumming.
That was a great time in my life - one that I think of fondly.
My brother-in-law has three sons. There's a fourteen-year gap between the oldest and youngest. While I agree his oldest son may require his own room, the two younger ones are close enough in age that it shouldn't matter. Ever. Sure, the chances brothers will begin jacking off together increase if they share a bedroom. But separating them is no guarantee they won't.
Truly, there is nothing wrong with brothers enjoying themselves like this - as long as it one is not forcing it upon the other. According to a psychologist acquaintance of mine, brothers stroking cock with one another is extremely common.
It should be accepted by parents - especially Dad, who should remember his own horny youth when hormones went crazy and he spent every possible moment playing with his cock and jacking off. And, perhaps, jacking off with his own brother(s) or buddies.
