Someone comes into the room

Sarah and Mandy burst into the room, Sarah looking quite angry. Meg leans back, letting your legs take a more relaxed position, and glares at your sister. You briefly think you'll be getting out of this, dignity (mostly) intact, before Sarah shouts, "Hey! You said you wouldn't start without us!" You feel a weight in the pit of your stomach, which you realize is going to be filled very soon.

As Sarah turns and locks the door behind them, Mandy unfastens her pants and pulls them down, revealing her nine inches of meat. Though not terribly thick, her balls are very large, swollen with cum. As she kicks off her shoes and tosses her pants into the corner of the room, Sarah unzips her fly and pulls out her thick, veiny cock. It swells in her small hands, growing to its full ten inch length, its substantial girth being much more intimidating than its length.

Meg snorts derisively at your sister. "Whatever, I still get him first!" She shoves herself forward, meeting brief resistance before burying her cock in your ass. Searing pain shoots through you, and you clench your anus reflexively, which only serves to worsen the ordeal. She starts pumping your ass, slowly at first, but in less than a minute she's already pounding against you, her thighs slapping against your cheeks.

While you were... 'distracted,' Mandy has climbed up onto the bed, and straddled your chest. She presses her stiff rod to your lips, rubbing the head back and forth against them. "C'mon, open up, I wanna try it, too!" You planned to ignore her, but one particularly fierce thrust from Meg strikes directly against your prostate, forcing a moan out of you. That is all the opportunity Mandy needs to slip her cock right into your mouth.

As your tongue runs across the head of it, she shivers in pleasure, and pushes herself in as far as she can. Holding your head against her groin, cock throbbing in your throat, she groans quietly before slowly withdrawing. She starts to piston in and out, back and forth, head and shaft rubbing against your tongue. With every stroke, her balls slide across your chin, and her thin blonde pubic hair brushes against your lip.

Meg's pounding intensifies further, watching her friend's ass swaying back and forth in front of her. She squeezes your legs hard, and presses herself against you, moaning incoherently as her cock throbs in your ass. She pumps her seed into you, grunting and grinding her hips against your own. Finally, she pulls out, her flaccid cock sliding out of your abused hole and slapping against her thigh. Cum oozes out of you, dripping onto the floor below.

Mandy's own thrusting has intensified, and with a shout, she stiffens and begins shooting thick ropes of cum into your mouth. Her stringy jizz slides across your tongue and down your throat, forcing you to swallow, which only means you wind up sucking the sticky cum straight out of her shaft. After several seconds of this, she's left panting above you, seemingly in a daze, her cock resting in your mouth.
