I don\'t want to be fucked in the anus but my boyfriend convinces me

This girl is very shy about sex and is afraid to try new things in bed. She currently has a boyfriend and he is the opposite of her, he likes to experiment with sex toys, positions and condoms of different flavors. They have been together for two months and he can't believe she won't let him penetrate her anus. She explains to him that she has never done it and that her hole is too small for a penis to enter, but after many conversations and trying lubricants, the girl lets herself go and her boyfriend penetrates her anus. He feels the greatest pleasure of his life because he feels that he took a new virginity from the girl and she felt a lot of excitement and pleasure for daring to do something new.
