Then Karin said," master let me serve you".
I said," Karin you know Alina is still inside the bathroom".
But Karin ignored me and began to lick my chest. I said to myself," when did this cute little girl become so horny. Hey it seems to be a sleepless night".
Then I said," Karin remember to hide when Alina comes back", saying so I began to tease her pussy.
While inside the bathroom Alina was enjoying herself and then looked at her shivering legs and said to herself," damm that guy, I will have my revenge but before that let's wash".
Inside the room, Karin sat on top of me and began to ride me.
I squeezed her small breast from time to time.
I then asked," Karin when did you become so horny".
Karin blushed and said," master as a slave it's my duty to serve you. So master doesn't talk nonsense".
Saying so she continued to move her hips and after some time she began to have her orgasm.
