Human ashtray of dominant nylon

Slave Bobby has to serve as a human ashtray for the dominant young nylon. Lying in the middle between the two, he has to keep his mouth open and receive her divine ashes. This really amuses the two sadistic girls. And they use his non-smoking mouth to blow their smoke. Again and again they blow the smoke into his mouth decadent and enjoyable and then give the ashes into his mouth.
