In her hair

Joey remembers that every time a girl has let him cum on her face she has said something like: "Sure you can cum on my face, just keep it out of my hair."

Joey smiles to himself, and moves into position to blow his load all over Rachel's hair.

"Oh man, this is going to be sweet." Joey thinks to himself.

He is jerking of faster and faster, and he feels his balls starting to tighten.

"Hi hi hi hi." Joey starts to giggle to himself as he shoots a string of cum right into Rachel's hair. The next string of cum lands almost right next to the third one, and the third one drips down on Rachel's face, running across her cheek, then down her neck.

Joey keeps jerking off until the last cum has dripped onto Rachel's hair, then stands next to her admiring his work.

"I guess that she will be surprised when she washes her hair tomorrow." He says to himself.

Rachel is still sleeping, not being aware that she has some very special hair gel.
