Bethany breeds her roommate

Bethany thrust her hips forward plunged into hot, horny heaven. Amanda’s virgin pussy was unbelievably tight - so much so that it hurt Bethany’s cock at first. For several seconds, Amanda’s tight nether lips refused to yield to Bethany’s girth. Eventually, however, Bethany titanic new strength won out. Amanda’s entrance gave out, granting Bethany entry. A deep, satisfied grunt escaped Bethany’s lips as she felt Amanda’s hot pussy sheath her mighty cock.

“Jesus fucking Christ! This feels amazing!”

“Bethany, it hurts! It’s too big!”

Bethany gazed down at her roommate and felt a strange sexual rage fill her.

“Shut up and take it, you little slut!”

Bethany pressed herself deeper, feeling her massive testicles slap against Amanda’s pert little ass. For a moment, Bethany sat there with her manhood buried deep in best friend’s sweet pussy. Foul energy filled the air at the desecration taking place. The wicked light in Bethany’s balls flared brighter as demonic energy pumped into the girl-beast’s veins.

“Bethany! It’s too much!”

“I’m too much? I haven’t even gotten started!”

Bethany withdrew her cock until only the bulging head remained inside Amanda. Then she thrust her powerful hips and slammed into Amanda’s back walls. A loud slapping sound rang out as her balls hit against Amanda’s skin.

The beast was taking over. Bethany could feel herself giving in to pure lust and desire. Her hips thrust on pure instinct.

Never before had Bethany felt this good. Goddamn, was this how it felt on the other side of things? She could feel Amanda’s tight pussy stretching around her. It felt good to be so big. So powerful. Her cock was mighty and thick. With it, Bethany was rapidly reducing Amanda into a mewling little slut.

Already, Amanda’s body was beginning to change to accommodate Bethany’s size. With each thrust, Amanda’s push took the mammoth cock easier and easier. Soon, cries of pain turned to moans of pleasure.

“MORE!” Bethany howled. “I NEED MORE!”

The demonic crimson of Bethany’s scrotum began to spread like an infection. Veins of red snaked up the girl’s huge penis, tainting the pale flesh. The throbbing veins along Bethany’s length turned from red and blue to black.

“Bethany! Bethany! Fuck, Bethany!” Amanda babbled. The girl’s skinny thighs wrapped themselves around Bethany’s thick, muscular torso.

“I NEEDED THIS,” Bethany growled. “I NEEDED YOUR SWEET PUSSY, AMANDA!”

Splashes of red raced up Bethany’s washboard abs before enveloping her bulging tits. With each thrust, Bethany changed more and more. Her eyes filled with wicked light, turning from blueish green to a sickly orange.

“Fuck, this feels amazing!” Amanda whimpered. “Don’t stop!”

Nothing on this planet could stop Bethany at this point. Her immense strength was focused on a single goal: fucking Amanda’s brains out. The red stretched up her thick neck and crawled across her face. Her pale blonde hair turned a bright, platinum white and grew thick and wild down her thick back.

“WHAT IS HAPPENING TO ME?” Bethany howled.

Immense pain erupted in Bethany’s forehead as two sharp points erupted from her skull. The points elongated inch by inch into a pair large black rams horns.

Bethany moaned and her entire body shivered as she tumbled over a precipice. Her transformation was now complete. Her massive testicles twitched and her cock throbbed. Deep within her, a flood of thick, boiling seed launched out of her penis, jetting into Amanda’s soft, **** insides.

“Eek! It burns!” Amanda cried.

“Take it, my love,” Bethany said softly. “Take it all into you.”

Amanda squirmed and convulsed as Bethany’s fell seed absorbed into her innocent body. Black veins snaked along skin that grew paler by the minute. Bethany watched in wonder as her essence changed the girl. Two months at college had done a lot to bring the mouse out of her shell, but it was nothing compared to the effect of Bethany’s lust.

Amanda’s skinny body filled out in a lovely way. Her small breasts grew bigger lusty pulses of growth, settling somewhere in the double d range. The girl’s lips plumped up, her face went from cute to drop dead gorgeous, her brown hair turned as dark as raven’s feathers. By the time the transformation was complete, Amanda looked like a goth Aphrodite.

The newborn demon relished the last few seconds of Amanda twitching on her thick cock. Her bride was lovely. Buxom and beautiful and fully devoted to Bethany.

Finally, Bethany withdrew her penis from Amanda with a loud, wet pop, sending a final jet of inky sperm splashing onto the girl’s pussy in the process. The demon’s head spun. So many things had happened so quickly. It would take a while to get used to this new body. It was scary, but also wonderful. Bethany’s mind wandered to the hall beyond her dorm room. There were other girls out there. More pussies to paint with her black sperm. Bethany sat up and stretched her muscular body, readying it for more fun. Her eyes dropped to the discarded “mystery box”.

“It sure was a fun mystery,” she said. “And Something tells me the fun is just beginning!”
