Yes.

You nod a bit sheepishly, and Rasna smiles placidly, then approaches you.

She turns, and elegantly takes a seat on your lap, her ass coming down right on top of your erection, the weight making your penis start to bend for a moment before it is pushed up against your stomach. You could swear she presses backwards against your cock on purpose...

The sudden intense sensation of rubbing up against Rasna's gorgeous ass makes you buck your hips involuntarily and begin prematurely ejaculating all over the seat of her pants, as well as your shirt and stomach.

Rasna remains sitting calmly for a moment before rising and turning to give you a disapproving look.

"You got my pants all dirty. I only see one way for you to clean them."

Her voice is firm and commanding as she turns again, this time lowering her ass onto your face. You feel the unpleasant squelch of your own cum as Rasna presses her sullied ass into your face.

"Start cleaning boy. Lick and suck your slimy goop out of my pants."

The idea is disgusting, but it's a little tough to breathe when Rasna presses down and you can't exactly run away while tied up as you are...
