As always, both comic book logic and crazy sex fantasy rules are in effect.
*****
Superman woke up with an undeniable need for a blowjob. That was pretty unusual, considering that he had women throwing themselves at him basically all day every day. Usually he went through each day and night in a state of satisfaction, but for whatever reason that morning his balls were aching.
Maybe it was because he didn't have anyone with him that morning. Though usually he literally slept with several of them after sleeping with them figuratively, running a good fraction of Gotham was hard work. Sometimes the others had duties, or just something they wanted to do. Considering that they were happy to let him fuck them at practically any time, he had no problem with that.
This morning, though, he needed to come and it had to be a blowjob. Hopefully he'd get one at some point during the day.
Instead of rolling out of bed, Superman floated straight up, letting the sheet slide off him. His costume lay on the floor where he'd left it and after a moment he decided just not to put it on. Most likely he wouldn't need to leave the Batcave that day and if he did, he could get his suit in a second. No one would be offended if he just floated around with his half-hard cock swinging between his legs. Probably quite the opposite.
The halls of the Batcave were empty and quiet, as they often were in the mornings. Superman listened for heartbeats and decided to float down the hall toward the waterfall entrance. There he found Poison Ivy bent over her plants with a thoughtful expression.
She'd asked him to divert some water and transformed one of the spare trophy rooms into an arboretum. There was an astonishing array of colorful and exotic plants on all sides in addition to some of her own unique creations. Superman had used those vines for many a fuck session, but at the moment they hung empty from the ceiling. In the midst of it, Ivy wore nothing but a red shirt barely buttoned over her chest and a few vines, as part of the landscape as any of the plants. She was coaxing a luminous purple flower from a tall stem, too absorbed to notice his presence until he was directly behind her.
"Good morning, Ivy."
"Oh!" She whirled and then smiled affectionately. "I didn't hear you come in." Her eyes dropped to the space between his feet and the floor. "Of course I didn't."
"What are you working on?"
"Just some plants better suited to Gotham's environment. The dark and the smog choke out most plants, but I think it should be possible to make species that thrive on it. Not that it will make much difference..."
"If it can convert some of the carbon dioxide, it will help. But I didn't come here to talk about that."
Ivy had been looking at the plants around her feet, but at that her eyes slid upward. Her eyes caught on his cock, slowly admiring the length. A familiar smile slid onto her full lips. "What are you in the mood for, then? I'm still a little sore from last night, but..."
In answer he tapped his finger on her lips. Ivy immediately slid her lips around the fingertip, keeping her eyes locked on his as she sucked it a few times. His desperate need transformed into a rock hard erection and she smiled as she slid her fingers around it. Ivy caressed his length sensuously as she slid to her knees in front of him.
Her ruby red lips kissed the head of his cock, then slowly slid over it. After so much practice, she could take most of his length with impressive ease, her eyes never once leaving his. Once she had him good and slick, she began moving, slowly at first, letting her tongue tease him along the way.
What Ivy had mastered, more than any of the others, was the visual aspect of a blowjob. In addition to her perfect eye contact, she managed to arch her back so that her breasts were pushed forward, brushing against his thighs, and her ass stuck out behind her. With anyone else it might have been teasing, but Ivy somehow she made it obvious that all of her was his, compressing all of her intense sexuality into her mouth as she moved along him.
Her eyes flashed as she saw his enjoyment. Not breaking her steady movements, Ivy undid the only button on her shirt. It fell open, yet only partially revealed her breasts. The fabric slid back and forth around them as she moved, offering tantalizing glimpses of the full globes.
Since he was concentrated on his own pleasure, it wouldn't be long now. What brought him over the edge was the sign of Ivy's own desire. Her eyes and her movements screamed her need for his cum without any desperation to break the sensual experience. When he finally came she expected it, taking in his entire length and swallowing each jet as it hit the back of her throat.
Superman sighed deeply and floated back, removing his cock from her mouth. Ivy sank lower, her back still arched. When she opened her mouth, he saw that a lot of his cum had stayed inside. She swallowed with a smile and then opened her mouth again, a perfect picture of readiness.
He was hard again and could easily have fucked her silly right there, but yet somehow he wasn't entirely satisfied. Superman left her with a quick kiss and floated back into the halls. That had been what he needed, but not everything he needed.
When he floated into the main chamber, he found three women already there. Barbara was deep into some information on the computer on the far end and would be difficult to distract. Catwoman and Harley were much closer in one of the livable areas they'd set up. Selina was examining one of the bizarre keys they'd captured while Harley polished her hammer. When she saw him, she dropped it in order to clap her hands gleefully.
"Ooh, Supes is going around starkers! Me likey!"
Selina raised an appreciative eyebrow. "Well, someone is up early in all kinds of ways."
"Ha ha, it's funny because penis!"
Superman floated closer to them and smiled. "I'll be straightforward, then: I'm in the market for a blowjob and I'll take the best offer immediately."
"Ooh, me, me! Or, wait, ooh! Both of us? Is both good?"
Before Selina could give any kind of counter-offer, a low voice spoke from behind. "I can do better than that." Calendar Girl walked up behind him and slid her hands around his chest, bringing her lips near his ear. "I was in the fashion industry for a long time... I have no gag reflex left. I've almost come sucking far uglier cocks, so you can imagine what I'll do sucking yours."
