Of course

Your painfully punished penis punches against the confines of its cage again and again. Cum pulses from the tiny hole of its prison against your will and its own well being. Your meager seed dribbling down your pathetically compacted manhood as your girlfriend watches with rapt attention.

You fall to your knees in bittersweet pleasure. The sight of your girlfriend's intensely ravished form is more fuel for your lust than you could possibly handle.

Carrie, whom you fully expected to mock every second of this pathetic display, goes oddly silent. The hand that had originally cupped her mouth to stifle her laughter now slowly trailing down to her womanhood.

The fact a cleanly carved path to this end exists through the topography of your sister's monstrous emissions is not lost on you. And this powerful reminder of her deific sexual performance mixes with the confusion of the display.

Your denied dicklet pumps and pumps and pumps its little squirts of faux-manhood against the hardwood beneath you as Carrie smirks and pleasures herself to your unintended show.

Each dribbling pat of your scrunched sack's wasted discharge makes Carrie bite her lip harder and finger herself a little faster.

Eventually your whimpering display ends and your girlfriend slowly walks over to you, tossing her folded clothes aside and freeing up her hand to grab the back of your head.

She pulls you dangerously close to her dripping quim. She's wetter than you've ever seen her before. Her shaven innie drools its arousal so fiercely that a few weeping strands fall between your splayed kneeling legs, inches away from giving you precious sensation.

You look up at Carrie as she pulls your head back sharply, but before you can speak she gently places a finger to her lips and quiets you.

"Ahh ah ah, no talking for my little guy, OK?" She tuts.

You feel her left foot raise and start trailing down your stomach until she has your balls beneath her toes.

You give her a pleading look before she says, "Now now, did someone cum without permission again?"
Before you can protest she begins gently stepping on your taut little grapes. The soft tacky flesh of her foot quickly exerting a threatening pressure on your precious pebbles.

But before things get any more intense, Carrie seemingly has a change of heart and says, "Luckily for you, seeing you cum so hard at just the sight of me was a pretty big turn on. So I don't think I'm going to step any harder, but for cumming without my say so you're definitely not getting unlocked yet. Nod, if you understand."

Her grip on your hair loosens and you give her two slow nods, the pressure on your imprisoned package easing slightly. "Good boy." she says.
You breath a sigh of relief, but then notice her snake your package in between her big and first toe and press down again.

"Don't be so relaxed yet, I said I didn't think I was going to step any harder, but if you want to avoid your punishment you are going to have to earn it." She sings.
"Eat." comes the order from above, and without a second thought you begin leaning towards her glistening entrance.

Immediately your head is pulled back sharply, and the formerly gentle grip on your balls is dialed up to eleven.
"Waagh, ung what did I do?!" you exclaim, before this treatment intensifies. Her grip on your hair becoming increasingly painful, and the weight on your nethers becomes crushing and rhythmic.

"Firstly, I didn't give you permission to speak. Secondly, I told you to eat, and pathetic little cucks like you don't even get to touch my pussy, unless they've been very very good. You understand?"

You quickly nod, the pressure easing up again.

"Good boy. You're going to be helping me eat all of your sister's thick perfect cum off of my body. Won't that be fun?" Carrie taunts.

Releasing your hair, you look up at the smug glazed form of Carrie and realize just what an incredibly daunting task that may be.
