A girl with an Alexa logo on her butt

There, in the middle of the room, stood a petite woman with a blue Alexa logo tattooed on her butt.

Oh my gawd, who is this!? She is hot! Where did she came from? Jacob asked himself as he saw the girl slipping on some briefs of his father.

Intrigued he watched her getting dressed in the undies when suddenly he felt a certain stiffness in his pants. "Damn.." he muttered.

Unfortunately the girl heard this and quickly turned around.

"Who is there?" she asked afraid.
