My sister-in-law was beautiful and often came over to our house. Unconsciously, I fell in love with her. One day, she suddenly started seducing me. Whispering in my ear, she said, "I like your brother, but sex with him is boring... would you lend me your cock?" When she found out I was a virgin, she got even more excited and forcefully took my virginity with a bareback creampie. From that day on, she began forcefully taking my cock every day, repeatedly having creampie sex with me.
