Naughty Big Brother Attacks Sister Masturbating

Synopsis

Tonight, our parents are out on family business.

I’m left home alone with my sister.

As the night grows late, my sister prepares for bed in her room.

When she’s alone, I peek inside to check on her.

Then I hear her soft breathing…

…Is she masturbating?

Curious about my sister, I burst into her room.

Flustered, she denies it.

But I press her about it and force her into sexual play with me.

I strip naked in front of her, showing off my erection.

My sister is flustered by my nakedness, but she can’t hide her interest in my growing member.

Soon my sister submits to me and starts playing with my cock.

I then attack her in return.

My sister, having lost all will to resist, surrenders herself to me.

Until morning comes, I release my pent-up semen inside her over and over again.
