I took my friend's sister, it was her first time and I complained a lot, but I think she liked it, I hope

A friend told me that her little sister wanted to have sex with a man, but she is not well with boys. she wanted to know what he was. all of her school friends had already experienced this. he asked me if i could have sex with her and i accepted her. we went to a hotel, my friend waited outside, but he told me to film everything. she was ashamed so we didn't take off her clothes, I turned away and started taking it, first with care, then with more force. it looked like it hurt, but I kept going. after a while, she started to like it. I think next time she will call me
