Jessica fills her pussy with sharp push pins. First she fists herself to stretch her pussy big enough to insert a see-through cylinder which keeps her vagina open to pour the push pins in. Then she grabs a brush and uses it to keep the pins inside while she pulls the cylinder out. So now the sharp stuff are pushed against her vaginal wall directly. To top it all she fucks herself with a long dildo while the pins are inside and she also uses a vibe on her clit. She moves on the dildo up and down vigorously and she cums pretty quickly. In the end she removes the push pins from her pussy using her fingers.
