They show my boyfriend wanting to insert breast milk into my anuses – it hurts me and he scolds me for it

This one’s quite vulgar, my boyfriend is a young amateur he said to try his milk in my backdoor naked. I sometimes refused, and yet, I complied. It was a rather discomforting feeling that Stew; it was a painful sensation. He scolded me for not being flexible-minded and thus we had an embarrassing conversation regarding our sexual orientation.
