Jane needs a seat!

Jane has her slave on some stools and uses his face as her seat, while she's playing with her phone.

If a girl is on the phone, she forgets normally on what she's sitting, so his face gets mercyless squeezed under her ass and the air-supply has also some longer breathing breaks.

She tells on the phone to her friend, how is her seat and may be she will lend him (her friend is 30 kg/60lbs heavier, but who cares)
