Yes

You try to respond but your voice is muffled by her ass. She slighlty raises her ass up, allowing you to respond. "I swear I'll be your ass ****" you desperatly gasp out. "Then beg to cum" she responds. You immediately obey "Please Mistress let me cum" you pathetically gasp out. Seemingly satisfied she slams her ass back down on your face and starts jerking you off again. You cum just as you pass out.
