"Very well, kneel for me," she tells you, "and take a praying position, it's easier that way." She begins jerking her masculine bits as you oblige, get harder and larger. "Now, just do everything I say and you'll be cum in no time." She puts her cock's head in front of your face and you see the slit open slightly.
"Push your hands in." As you do, you feel the opening give way, but only enough for you you get in to your wrists. The shaft squeezes on them tightly, and it feels like it's sucking.

"No idea, but I hope it's somewhere fun." You shift about again, getting comfortable, and soon you drift off to sleep.

You think it's a little odd that you retained your consciousness after digestion, but your thoughts are interrupted as you feel pressure building up around you.
