Dance class

I recently joined a Kizomba dance class and the teacher has large firm breasts like mine, all the girls at the class have to take it in turns to learn the dance with her but when it came to my turn her breasts pushed so hard into my breasts as she held me tight, she did some moves with me and all I could feel were our breasts grinding against each other, I would like to no if this can do any harm to them as I have 32EE breasts and hers are a 34F, they are also firm for there size, it's just that she really makes her breasts push so hard into mine and was just wanting to no if it's ok or not ?
