Is it normal with my boss

hello everyone,the thing is i am 19 and my boss at work is 50 years old,i was on my lunch hour he confronted me infront of everyone.can you come to my office,i then get in there he just came on to me kissing me i was pretty turned on by this,he then pulled his cock out from his trousers and said (go on suck it)so began to suck after about 20 mins of that he came all in my face.
is it normal i feel ashamed becouse of the age?
