May set up her own transport portal and Auchery offered Sybari her bird-like hand to get down. When her feet hit the floor, a blob of cum splattered between her feet. It wept out of her gaping hole with every step, making her thighs slippery. She stopped herself from letting go of Auchery to stroke her clit. May had the portal open, a dark black tunnel of void. She took Sybari's other hand and together the three of them stepped inside. The rush of wind swirled her hair and it felt like she was upside down. Suddenly it stopped and they were standing in a room of the castle. May led them out of the dank room and through the passages to her suite. Sybari went straight to the bathroom to wash herself. There was a neat hose for cleaning herself out, but it still took some time to flush all the cum her body hadn't absorbed from her insides. She'd also gotten distracted by the need to masturbate.
Once dry, she pulled on a simple dress and a pair of panties May had left for her. They bulged obscenely at the front where she'd tucked her swollen clit. The sight turned her on and she cupped the weight of it in her hand. She had to stop herself from rubbing it and force herself to leave the room. Mayhem and Auchery sat at the little table in the fountain room, sharing a drink. Seeing she was done, May went to take her own bath.
"I bet you're thirsty." Auchery poured a bubbling liquid into a glass for her.
Sybari nodded and gratefully took it. She barely tasted the liquid as she gulped it down. Although she tried to sit down, she was immediately uncomfortable. Her clit was hot and sensitive, demanding attention despite her having just cum in the bath. She jumped up out of her chair.
"Excuse me. I have to do something."
More like she had to fuck something. Namely, herself. Before she tried to fuck Auchery.
She hurried into the bedroom and stripped off her dress. The lump in her crotch instantly excited her and she felt her already wet panties soak through. She wriggled them off and sat down against the wall, her hands going straight to her ten-inch clit. She pumped at the shaft, her hips bucking. Her tail slid easily through the slimy entrance to her vagina and began to pump at the same pace. She panted hard, trying to finish herself as quickly as possible. Juices wept plentifully from her pussy, forming a large puddle under her butt. Throwing back her head in climax, she stifled the accompanying moan. As she leaned against the wall gasping, her clit throbbed, visibly pulsating between her legs. But her session had done nothing to diminish the feeling and she took hold of it, desperately trying to jerk herself off again.

It took May a minute to notice Sybari against the wall. The succubus didn't hear when she came into the room. She was too busy masturbating her jumbo clit-cock in a pool of her own cum.
"Didn't you get enough?" May said with amusement. She noticed Sybari's expression and her face turned serious. "Are you okay? Is it hurting you?"
Sybari looked up at her, distraught. "I'm so fucking horny. It's not going away."
"You did take in a lot of energy. It might take a while to dissipate by itself. Would fucking me help?"
Sybari nodded, never stopping the pumping of her clit. "Please. The more sexual energy I use, the less there'll be."
"Let's get up on the bed then. You've made the Ruby Sea down here." May pulled her to her feet and walked her to the bed. She wasn't sure what the best way to do this was. She was taller than Sybari, so standing wouldn't work and cowgirl was a strain on her thighs. She also wanted Sybari to be able to control the pace.
May sat on the edge and shuffled back. She lifted her legs to remove her underwear and splayed them wide in invitation. Sybari crawled on top of her, covering her mouth with a deep kiss. Her hands groped May's breasts through her dress and her tail flicked gently across her clit. The spade circled May's vulva as they kissed, eliciting moisture from within. It poked through the puffy ring and slid deep into her pussy. May brought her tails up behind her lover's ass and twisted them together. Sybari was so wet, her lips parted like warm butter and May had several inches inside her without trying. Sybari broke their kiss to let out a moan. She ground herself against the tails, one hand going to her clit. There was desperation in her, like she was trying to hold herself back. May cupped her face.
"Sybari, I can see how much you need it. You can put it in me. I'm aroused enough to take it."
Her forehead wrinkled. "You mean my clit?"
"It's hard, isn't it?"
"Yeah, but...you don't like cock."
"It's not so much cocks themselves as what's attached to them." She stroked her cheek.
"But I love you, and I love being penetrated."
She bit her lip. "Are you sure?"
May kissed her. "I want you to fuck me with your giant clit just it as much as you do."
Sybari lined up the tip of her clit and pushed the thick rod through May's labia into her vagina. The first couple of inches went in slow, then Sybari thrust the remaining length to the hilt. Although aroused, May wasn't stretched yet, so the size of the thing forced her walls apart quick enough to make her feel like she was being impaled. She gasped and dug her claws into Sybari's skin.
"Sorry! Was that too much?" Sybari asked.
May gave her scolding look. "We were using a dildo bigger than this three days ago."
"I know. I just haven't done this before and I don't want you to be uncomfortable."
May continued to give her a bored look.
"Okay, okay, I'll go back to fucking you."
She pulled her clit out nearly all the way and slammed it back hard. She repeated the motion until she got the hang of it, quickly building up speed. As she hammered into May, juices leaked from her pussy. The copious amount made loud squelching sounds every time May pulled her tails out. Sybari was soon whimpering, lost in the experience of her dual stimulation. Her thrusts rose to a wild buck that made May roll her hips and squeeze the shaft within her. Then Sybari went stiff and her vaginal walls clamped around May's tails. She let out a howl of ecstasy and slowly collapsed onto May. Her clit remained lodged inside May, thick and throbbing.
"Let me finish you," Sybari said breathlessly, pushing herself up so she could restart her thrusts.
She was soon back to a jackhammer pace, which brought May to the edge and flung her over. She wrapped her legs around Sybari, who continued at the same speed throughout her orgasm. As May regained the movement of her limbs, Sybari sawed in and out of her, building herself for another climax. May helped her along with her tails.
"Aaahhhhh, fuck, May," she gasped, her mouth hanging open. Fluid gushed out of her pussy, dribbling down her legs.
Sybari withdrew her pulsing clit and flopped on the bed next to May, panting hard. May combed the hair off her face and kissed her head. After catching her breath, Sybari sat up and crossed her legs.
"Did that help at all?" May asked, pushing herself up to a seated position.
"A bit." Sybari wrapped her hands around her clit-cock. "I think it shrunk a little. Maybe half an inch."
At this rate it was going to take a lot of fucking to work it away.
"Can you shift it like you did with the humans?"
"Temporarily." She sucked in a deep breath and slowly drew form from her clitoris. As it shrank, her breasts swelled plump, her nipples growing another couple of centimetres so they poked out lewdly. "It's a party trick. I can't hold it for long without the energy going back to my genitals."
"They're nearly as big as Auchery's." May curiously gave one boob a squeeze, eliciting a moan from the succubus.
"It also makes that area hypersensitive," Sybari breathed, unable to help herself from groping them.
The transfer of mass hadn't returned Sybari's clit to its normal size. It was still four inches long and only a bit thinner. Still, it gave May an idea.
