"I remember back in my youth around cottages, it was not uncommon to find a cock smelly, and once it was out and presented for sucking it was a brave person who refused, especialy once a cock was hard.
A lad I knew, once refused when the hard cock was pressed to his lips, and was given a good hiding, he also lost two teeth.
My solution was to slaver on it, and get rid of the nasty taste as quick as possible, (no wet wipes in those days) and of course avoid the guy in the future, which was not always possible in a dimly lit cottage, or dark area.
Being a known cock sucker, or even as it was known then a bum boy, in a small town, it was difficult to refuse any requests, as the person would likely ridicule you in public, and then there was the risk of the queer bashers catching you one night, some of whom I'm sure I would have sucked off at sometime.
All sex in those days was bareback, condoms were for use on women. I was often fucked by married men, and one thing was common, that was once they had cum, they insisted on being sucked clean, always for the same reason, incase the wife wanted sex when they got home.
