My best friend Karen taught me how to make love.

My best friend Karen taught me how to have sex. I have my first girlfriend and we are preparing for romantic dates. I am clumsy when it comes to dating, so I asked my childhood friend for advice, who is the girl in my class named Karen Yuzuriha. Not wanting my girlfriend to think that I'm a virgin and know nothing about sex, I asked Karen to teach me about it. She helped me practice in a way that made me forget all about my girlfriend; Karen certainly has a lot of experience in SEX.
