Softly awakening my untouched sister's desires

When my sister's friend visited, I teased her with my monster cock. Her innocent look turned to lust as she touched it, leading to passionate sex, leaving her moaning in pleasure.

After a long afternoon of work, I found myself in the company of my younger sister, who was eager to share with me the fantasies that had been haunting her. The girl was clearly aware of her own desires, but she was afraid to express them. So, in a soft voice, she asked me to fulfill her dream. And here is how it all began. The girl lay on her back, and I gently spread her legs, revealing the moist folds of her pussy. Then, with my fingers, I began to gently caress her, before slowly penetrating her with my hard cock. The girl moaned softly, as she experienced an orgasm, which was the first in her life. It was a wonderful moment, and I hope that my sister will not be afraid to express her desires more often.
