Good to see a bottom who enjoys sucking off us men.
The man would correctly be called a bisexual Top.

Sure, an old "straight" guy who shaves his balls but accepts a blowjob by a man!

Come on I don t buy that he is straight. If he was straight he wouldn t shave his dick in that age, unless he was still active in sex which would make him not get involved into gay sex just to cum. He would simply enjoy straight sex.
