Girl with pigtails in a cap is fucked in the first person

I’m definitely not a psychologist by any means, but I still can’t understand why my stepsister came to me asking me to have sex, and when I came inside her in the process, she was offended, but that’s definitely not my problem anymore! And first you need to learn the culture and not enter without knocking. And don’t listen to friends who did such dirty things and liked it, friends can be wrong.
