可愛い義姉が昼寝をしている間に、僕はオナニーしてお口の中で射精。

My shy stepsister is afraid because it is raining and thundering very loudly outside, I tell her that we should share my bed and take a break with me, what she doesn't know is that while she is resting I masturbate really well and pour my milk into her face and swallows it
