I have a very beautiful and obedient younger sister. Even though she is at the most beautiful age of her youth, she has never had a love affair. As a responsible older brother, I always care about her, so one fine day, while her parents were away from home, I helped her know what the feeling of happiness in love is. We made love for a long time and she must have enjoyed it too, especially when I ejaculated into her vagina, she kept moaning in pleasure.
