“Might as well get this started,” Raven mumbled, crawling up on top of Beast Boy. Her breasts pushed against his chest and her thighs rubbed up against him legs, sending shivers all down Beast Boy’s body. Just being touched by Raven was turning him on. Raven moved down Beast Boy’s body, rubbing herself down against him as she went. Beast Boy gave a cry of anguish and pleasure when he felt his cock rub against Raven’s ivory skin. When she finished getting into position, Raven was on her knees at Beast Boy’s feet, facing away from him. Soon after, she leaned her body back, letting her cape flap quietly behind her. Lifting herself up, she finally dropped her butt directly onto Beast Boy’s together-pressed. He yelped when he felt his toes rubbing against Raven’s soft buns. Raven wiggled her ass back and forth, digging Beast Boy’s toes into the doughy fat of her pale backside. She continued to push her ass down over him, until one of his feet started to dig into her crack. On the tips of Beast Boy’s toes, he felt a small, rubbery opening rubbing against him. Raven dropped some of her weight down and the narrow opening started to widen. More and more of her weight came to rest upon his feet, and the opening continued to pass and slide down his foot until it covered everything. With a sick plummeting feeling deep in his belly, Beast Boy realized that what his toes had been pushing against was Raven’s anus and that even now his foot was sliding into the girl's rectum.

Her slick sphincter wrapped tightly around his foot as it moved over his ankles and continued gliding forward. Raven lowered her hand slowly, breathing heavily from the small insertion into her rectum, and grasped Beast Boy’s free foot. She maneuvered the foot into her crack and placed it beside Beast Boy’s already inserted foot. With a push, Beast Boy’s other foot slid into her bowels next to his first. Now that Raven had both feet inside her, she started putting more pressure down, slowly starting to pull in Beast Boy legs.

“Oh God, oh God, oh God, oh God, oh God,” Beast Boy kept on uttering as he felt more of his lower body slide into the tight backside of the girl he loved. The edges of the anus peeled back, pulling Beast Boy further into the humid, small and tunnel-like rectum. Her insides felt incredibly clammy and tense, unlike the wetter stretchiness of Jinx's cunt. No moisture dripped from inside Raven, making the journey slower and far more uncomfortable. His bare legs rubbed against her wrinkled anal walls, chafing his flesh and deepening his distress. The hot inner walls of the anal cavity closed in over Beast Boy, only widening enough to pull him in a bit. Every time Raven tightened her hips, another contraction would pulse in her rear and pull Beast Boy further in. Already her contractions had him up to his calves and they were slowly oozing over his knees.

“You can’t imagine how good this feels,” Raven panted, concentrating on widening her rectum. Lumps formed beneath the skin of her waist from Beast Boy's body entering hers. She frowned down at the protrusions in her skin; she knew that if this was going to work, there couldn't be any outer sign that Beast Boy was inside of her. This part of her plan was the hardest: she’d have to work some powerful dimensional folding magic, all while distracted by the intense pleasure of Beast Boy's body slipping deeper into hers. Finding her center amid the pleasure, Raven began her mantra.

“Azarath Metrion Zinthos!”

As the words left her mouth, Raven's body shone with a dark, eerie light. Slowly, the bulge in her middle grew slimmer and softer, and then disappeared entirely, leaving Raven smiling down at her once-more flat waist. She could do this; she was sure of it now. More relaxed at knowing her magic was working, Raven closed her eyes and let herself enjoy the elation as Beast Boy continued to be fed mercilessly into her ass.
“Why are you doing this?” Beast Boy screamed after finally collecting his wits. The feel of the oily center of Raven’s ass was making his skin crawl. He didn’t care that he was touching a part of the girl he loved; this was all too much for him to endure or understand. Maybe it wouldn’t have been so bad if he had been sliding up her cunt like he had with Jinx, but being squeezed up the tight, sweltering canal that was Raven’s ass was horrific. He could feel her body pulse around him as her sphincter tightened and swelled with immediate results. He could feel the crusty ring kissing his thighs as he was swallowed up with ease.

“Hehe, weren’t you listening when I was talking with Jinx? I’m doing this because it’s for the best. We can’t date, because we’re too different, but I can’t live with this lust I feel for you. So, I’m making sure that I always have you to satisfy my carnal needs, my love.”

“By putting me in your ass!?”

“What can I say, I really get off on anal.” Beast Boy just stared up at Raven, wondering how someone could claim to love another person while doing something this terrible to them at the very same time. Obviously, Raven was sick; if he could just get his arms to work, he could escape and get help!

“If you love me so much, why’d you let Jinx cram me up her crotch?” Beast Boy whimpered as he looked down his waist and nearly cried out. As they were talking, Raven’s anal ring had slowly slid itself over his thighs and was even now starting on his hips. The high temperature within Raven had spread and sunk into his legs, filling him with a deep sickness inside that wouldn’t go away. What would it feel like when he was up to his chest? What would it feel like when he was up to his neck? He didn’t even want to think about what it would be like if it covered his head.

“What’s wrong, didn’t you like Jinx’s going away present?” Raven chuckled, the motion flexing her ass around Beast Boy’s legs. “Your trip inside Jinx was part of our deal. She removes your powers, and I let her have her way with you. I might be an ass-lover, but Jinx loves stuffing big things in her greedy cunt. She just couldn’t give up an opportunity to unbirth a soon-to-be infamous hero.”

“What you mean ‘soon-to-be infamous’?” Beast Boy asked, feeling a small swell of pride that Raven would call him infamous. Even in this situation, he could still find his ego buried under his terror.

“You’ll be infamous for being the only super hero to spend the rest of his life up someone’s ass.” Raven's cold laughter turned his twinge of pride into sickening nausea. He had heard her say that she wanted him around to permanently satisfy her carnal needs, but he’d never have suspected that she meant to keep him up her ass permanently! Desperate, Beast Boy shuffled his hips, tying to stop the descent of Raven’s butt-hole, but his motions only stimulated the girl and worked his body deeper into her rank behind.

Raven felt her skin start to bend again as Beast Boy sank deeper into her flesh. Her mind was overflowing with so much pleasure that she could barely see. It was a terrible challenge to find her center and access her powers, but after a moment to block out the pleasure, she managed to weakly call out, “Azarath Metrion Zinthos.”

For a second time, her body glowed with a pure black light and her body returned to normal, apart from the sight of Beast Boy's body struggling waist-deep in her rectum. Her intestines were coiled around his legs, gripping him tightly and not letting go. Beast Boy could see his stomach being sucked into the ass now, nothing slowing him down, nothing left to halt his decline.
