Bestial orgasm on the bus

The woman is on the bus and she's traveling at a standstill because there are so many people. A very horny man is supporting her from behind, holding his dick up to her ass. She doesn't say anything and gets very nervous. When the man touches her pussy she is petrified, not knowing what to do. The man fucks her pussy with his fingers causing the girl to inevitably get horny and the pussy drips with juice. The girl's legs are left shaking in an intense orgasm
