Min flickvän ber mig att hjälpa henne med läxor, jag går in i hennes rum och jag kan inte stå ut med lusten att knulla henne, så jag kommer i henne

She asks me to help her with homework, that's why I go into her room and since I can't stand the urge to fuck her, and there's no one else there, I decide to lift her skirt and fuck her, I came in her after having sex.
