I lose control when i see my uncle on all fours at his desk in the office.

At twenty-three years old, i had no choice but to start working in my uncle's company. he is very serious and very bad tempered. i don't dare contradict him at all. the other day he calls me into his office and makes me undress. although i don't understand anything, he is the one who packs so i have no other choice. i'm not able to move when he takes my dick into his mouth and starts licking and jerking me nonstop.
