See what Cathy is up to

You head down the hall, out of your room toward your step sister Cathy's room. You pause before the door and think of her face, exactly like Carol, but different, just a little. She appears in your mind and you think, "You will not notice me. I am invisible in your presence". You then slowly turn the knob and enter the room. Cathy is on her bed, a pillow between her legs and she is humping the pillow with firm pelvic thrusts. She has the t-shirt she slept pulled up over her big tits and is using her fingers to twist and pull her erect pink nipples as she humps her clit against the pillow. You can see her pussy is soaking wet and the pillow is wet with her pussy lube as she humps it.

As instructed she does not notice you and you come close to her, your cock swelling to full erection as you watch her masturbate. You instruct her mentally, "Say out loud what you are thinking about as you masturbate. Tell me all your nasty thoughts".

Cathy complied with your request and said, "Fuck me with your big cock. Shove it in my pussy. Yeah, that's it. Fuck me hard, you are making me get off. Give me your big cock. Fuck, yeah I want you to cum all over my face."

She began to hump faster as she said this, her hips grinding her clit into the soaked fabric of the pillow, bucking her hips as she climaxed. Her fingers pulled and twisted her engorged nipples, pulling them firmly away from her big tits.

"Stop", you thought and the world froze around you. Cathy's face was screwed up in the pleasure of orgasm, her big tits and wet pussy on full display. You climbed up on the bed and started to jerk off quickly. Her tits were soft and you rubbed your cock-head over her breasts, and jutting nipples. Her mouth was open in the classic orgasm face and you kept jerking your cock until you were ready to blast your load. The first long cum shot went right into her open mouth, and you followed with five more long strings of jizz coating her face and tits with your sperm.

"Start", you instruct her again, and she chokes a little on the cum you blasted into her open mouth and then looks down in surprise at the cum covering her face and tits.

"What the fuck," you hear her exclaim.
