Becky wants to try her newly grown cock on you

By: Cheese111

Mike and Dan stood before your towering girlfriend, both still unmolested but positively drunk of her heavy musk. "Me next! Me next!" They crowed enthusiastically. It was disturbing to see your friends line up and beg to be abused. But worse yet was Becky's gaze stayed fixed on you.

"You're adorable, boys. But I want something a little sturdier. Little Willy, why don't you come over here and show them how it's done?" Her voice was sweet as honey, but you knew it was all a facade. If you refused, she'd unleash whatever she had in store for you onto your friends. And they wouldn't be able to survive it. With a pained grimace you try to get up, Kim moaning as your ass reflexively tightened around her cock. Big Willy slowly slipped free, your sister eagerly playing with it to keep it rock hard.

Slowly you get closer to Becky. If she was a little intimidating before at twice your size, now it was getting freakish. She would have to kneel down to bring your face in line with her junk. Her throbbing tower of lust was still fully erect, even after filling up three of your friends. And you were next. The moment you were in arm's reach she took charge, grabbing you by the waist and simply lifting you off your feet. The ease with which she could manhandle you was scary, but the look on her face told you her plans were far worse.

Becky turned you around to face your friends before lining up her cock with your abused asshole. A little bit of cum still leaked from it, Big Willy having done a good job of warming you up for the main event. You peer down at the thick cock about to enter. After everything she'd done to you over the last day and a bit you'd hoped to be more mentally sturdy, prepared for the horrors to come. But you're pretty sure that dick is going to snap your pelvis in two. Your horny girlfriend enjoyed watching you simmer in fear, but her primal needs were aching to be met. She lowers you down, two large hands around your waist ready to **** anything that wouldn't come naturally.

You gasp in shock as you feel the sheer width of her tip squeeze between your legs. It'd grown fifty percent larger since the last time it's done this, taking the girth from overwhelming to impossible. But Becky was keen to show that with a little bit of elbow grease she'd get it done. With a sickening squelch she begins the invasion of your ass, barreling through any defenses and plunging a solid foot and a half of her cock into your colon. You grunt and whimper, feeling your innards get pushed aside by the large shaft. Becky moans, relishing the relative tightness of her little Willy as she drives more and more of her huge cock inside. Your breath goes shallow as your lungs are squeezed between your ribs and the huge cock pushing up your chest. No matter how much damage it'd do in the process, you knew Becky would take this to the hilt.

No sooner had the thought crossed your mind as you felt her shaft bulging out your neck. She was utterly insatiable, ramming herself in ever deeper. You could feel your body strain and stretch to accommodate this nightmare. Thank whatever mad science Kim had used on you that let you handle this as you're pretty sure a human body can't warp and twist the way you are right now. The taste of pre pollutes your mouth as it bubbles up from your throat, the vile source not far behind. Becky thrusts, pushing her cock all the way through and filling your mouth with her throbbing spire. Your jaw felt ready to pop loose as the thick head of her manhood **** it wide open. Your eyes were filled with dread as you could only squirm weakly, your expression locked in fear.

"Aw, is Little Willy a bit too small for my cock. It's okay, I'm sure your friends can take care of the last part. Open wide, boys." Becky cooed, Mike and Dan eagerly stepping forward, staring down the barrel of her dick, seemingly oblivious to you being skewered on it.

Kim calmly strode up behind the two, inspecting their bare asses briefly before whispering in Mike's ear. "Want a little something extra to heighten the pleasure?"

He nodded feverishly before letting out a pained shriek. Kim only needed half a word before she'd taken his hips and rammed her foot-long cock up his rear. Mike clearly wasn't accustomed to that level of butt-play, tears welling up in his eyes as your sister gently humped him. Becky let out a small giggle. If he thought that was going to be too much, he had a whole world of trouble coming.

"Here it comes..." Becky grunted, lining the thick tip of her cock up with Dan's face. He understood the message and took hold of the sensitive bulb. Like a ghoulish parody of a kiss he tried to suckle on the twitching tip, Becky quickly delivering him what he so eagerly desired. You felt the rush of fluids push through her shaft, the pulsing flesh reaching a fever pitch as she unleashed a near literal firehose of cum right down Dan's throat. The moment he thought of pulling back Becky put a hand on his head, keeping him firmly in place until she was satisfied. His gut began to swell up with seed, his movements becoming erratic. "Ugh, fine, Mike, take the rest." She grumbled, switching targets mid-orgasm to spare Dan's life. Mike was slowly getting used to Big Willy pounding his rear. He was barely ready for your girlfriend to grab his head and **** the rest of her climax down his gullet. Kim moaned with barely any restraint as she too came, filling up Mike from the other end.

Dan had gone to his knees, clutching his heavy gut full of cum and locked somewhere between discomfort and pleasure. Mike only remained on his feet due to Kim propping him up with her cock. Becky let out a big sigh of relief. "Phew, almost thought it'd be too much for them. But now we're out of people to fill up..."
