I've noticed on many pictures of erotic models they they have those marks, is it because they wear extra tight bras or that happens also you? I didn't think it was so tight around your body...

A bra needs to be snug enough to stay up and support the weight of the breasts. Ideally the fully stretched length of the bra band should match a person's underbust measurement. For example my underbust is 29-30 inches so I wear a 30 band.
Red marks from the band are normal as long as they are not causing pain and go away in less than an hour after taking the bra off. Some people might have indents on their shoulders as well if they have larger breasts since the straps are supposed to provide a little bit of support. Some people wear bands that are too large though and have therefore make their bands support too much of the breast weight. That's when you end up with shoulder pain and deep indents on the shoulders.1
