My friend's younger sister is a somewhat mischievous girl who loves to tease people. She often teases me by saying things like, "You must be very popular, right?" "How many fuck buddies do you have?" "You must have a girlfriend too, right?" and so on.
I often eat meals with my friend and his sister, the three of us, so our relationship was very good from the beginning.
However, since she is my friend's younger sister after all, I kept telling myself clearly in my heart: "It wouldn't be good to develop that kind of relationship with her." So at first, I didn't take any initiative towards her at all.
But she had an unusually large amount of physical contact with me, and often actively asked if I wanted to eat alone with her. Later, I simply mustered the courage to ask her directly:
"Why do you always like touching my body so much?"
She answered me:
"Because I like muscular guys."
Then she suddenly said very directly to me:
"If it's with you, I'd want to have sex with you."
When I heard that, I was really shocked and felt a bit at a loss. But at the same time, I started imagining scenes of having sex with her in my mind, which made me incredibly excited instead.
After that, we discussed some agreements between us, and just like that, we officially became fuck buddies.
And this video is a record of one of our sexual encounters.
