He owes money to his friend and he pays him with some blowjobs

He still owed money to his friend, he felt terrible, but the other smartass had come up with a way to be at peace: his cock was getting hard just thinking about it. Come and give me some blowjobs, he said, and although the other did not want to, that little bulge in his underpants was too tempting, he should not owe him any money, and on top of that he would enjoy that big cock in his anus. Done deal.
