During the two days my parents were away, my sister's friend Maron-san (a slut) suddenly showed up and I, a virgin, was trembling inside when I saw her arguing with her... "Your sister is at fault, so you have to do something." What could I do!? Before I had time to think, she took my first handjob, blowjob, sex, and even creampie... Cute face, beautiful tits, and even though it was my first experience, it was too stimulating! "I like your dick (blushes)" I was made to cum over and over by her insatiable dick!
