An Experiment in Switching (Part I?)

"Put your tongue inside me further," she demanded while grinding her Mound of Venus against my chin, attempting to help the process...but based on the angle, perhaps it was to make me work harder.

"Rubbing your pussy mound on my chin like that makes the angle hard to put it in further," I explained. "And with this collar, attached to the lead which is tied to the bed, I can't lift my head up any more! Help me."

"Oh. Does this help?" She pushed my head down so that I was lying completely flat, and then scooted herself back. "Do you like looking at my pussy? DON'T answer...I know. Just stick your tongue deep inside. Stick it out as far as you can." She then proceeded to fuck herself with the tip of my tongue. "That's certainly not enough," she sighed while pushing her body more onto my face, to the point her asshole touched my nose. "That's more like it," she moaned while rotating her hips just enough to allow small gasps of air, but ensuring my tongue stayed inside. "I want you to hit my g-spot with your tongue," she explained as she sat up and spread her legs wider, making my face support her body...nearly swallowing my face with her ass cheeks. "Yes, that's good," she calmly said while rubbing her clit and cumming all over my face.

"My turn," I anxiously said.

"I agree...but not in the usual way. Let's get you cleaned up." She unfastened the restraints and told me to follow her to the bathroom. "Get in the tub. Get on your hands and knees. Now drop to your elbows." I knew what was about to happen. I'd given her several, but this was the first I was about to receive. How could I protest?

"I'll leave you alone to evacuate."
