How well you fuck, how it shows that you are my brother

He was his older brother and as such was always ready to teach him things, but he had little to teach him. they had been incestuous sex for several years, and neither of them cared. they carried their lives out of bed, but when they were together they always ended up fucking. that day they began to undress until they showed their erect penises and the youngest ate it to his older brother. then they switched to continue the other blowjob and started to penetrate each other. they liked to change, that's why first it was the young man who fucked her ass for a long time, both liked that. but after a while the oldest also wanted to put it in his young and hard ass, so it penetrated him as he usually did. the first to cum was the young man, he always won. later it was the older of the two who came after taking her out of his little ass.
