On her knees, of course.

Sue Storm got back down on her hands and knees. She didn't entirely trust herself to stand up yet after her legs still felt weak from the constant wracking of pleasure upon her body. She felt a little light headed too and didn't think she could even keep balance. Carefully she started to move forward, her eyes ravenous now, looking directly at his crotch, a clear throbbing bulge now tented his simple pants. She crawled on her hands and knees like a Bitch in heat.

This Superheroine, this practical Goddess. One of the most powerful and smart women in the world, this highly capable warrior and Mother, who was completely composed just moments ago was now crawling toward his cock like some kind of base animal.

An electric thrill shot up his spine.

He had to have more of this.

He had to have all of them now.

She made it to him finally, getting on just her knees now. Her starts to sit up straight before her back arches just a bit, thrusting her costume and apron concealed bust towards his gaze, the mere suggestion of her hard nipples starting to poke through her outfit a little. Her gorgeous blue eyes held a faux innocent look to them, looking up into his eyes, almost pretending like she didn't know the effect she had on him. But she knew all too well. She might have had the most sexual experience in this entire room. She knew how to play to her body's strengths, she knew how to tease, how to coax that delightful moan from somebody's lips, how to make somebody want her so badly they'll just take her on the spot.

She wanted to use all those tricks on him.

After all...

Her son only deserved the best.

Wordlessly she reached forward and loosened Mark's pants with her nimble fingers. Never breaking eye contact all the while. Her expert maneuvers got his pants all the way down as she finally looked away from his own eyes, and focused on what would permeate her every desire and dream for the rest of her life now. His thick, long, beautiful cock. The first thing she felt when she saw his prick was not lust, nor desire, nor love. But pride. She couldn't believe how lucky she was to have such a hung, powerful, dominant son for a lover.

Sue looked back up at him, her eyes filled with such affection and warmth. Her pink, glossy, thick lips mere inches from the wide swoop of his cock head. Her hot breath brushing against his shaft as her excitement rose. She offered up her first words to him since her enslavement, since she was given new identity, new purpose.

"Please." She said, her adoring tone mixing so powerfully with her motherly personality. Even just saying such a simple word stirred deep feelings of submission and powerlessness in her. Feelings that thrilled her to the core. "Honey, can I please suck your cock. It's so beautiful. I promise to make it feel better. Would you let me do that for you? Would you let Mommy suck your cock?"

His dick throbbed again. He still couldn't believe how quick the transformation was. Maybe she was already like this deep down. Regardless he got a sick, new thrill out of hearing her call herself his Mommy. He knew it was the right move. She clearly prided herself on being a great mother, tying that to her sexuality only made her natural lust exponentially stronger.

Mark reached down with one hand, cupping the side of Sue's face at first, strong fingers brushing against her blushing cheeks. Her skin so incredibly smooth and soft. It only made him imagine what the rest of her would feel like.

Reaching further back he tucked a blonde lock of hair behind her ear before holding the back of her head affectionately. Feeling the silky hair as she cooed at his touch.

"It's not just sucking his cock." Jean corrected her, surprising Mark with her enthusiasm. "You must worship it. It's what you and I, and all the others derive the most pleasure from. It deserves more than to be just sucked, you must give it your entire being. Everything you want, everything you could get pleasure from, it can provide all of that. It can bring you to heights you haven't even imagined yet."

"That's right." Ororo interjected. "It's what makes Mark happy. It's what makes everybody else happy. I know what a kind, loving person you are Susan. Don't you want to want that happiness not only for yourself, but to spread it to everybody else too?"

"God yes..." Sue responded, her breath more labored now as she became more and more excited. Her enormous chest heaving as she really started to take in his scent too. It was intoxicating like nothing she'd ever felt before. "Please..." she whimpered.

"Do it, Mommy." Mark finally relented. Seeing her almost beg him for it was exciting beyond belief, but he could hardly hold out at this point as well.

Sue soft pink lips curled into a smile before her round, wet tongue spilled out of her mouth. The long appendage touched the base of his pole, before slowly dragging it along his entire length. His dick now slick with a long string of saliva before she went back and repeated the motion on another side of his rod. Her breathing getting even heavier as she continued, her excitement only rising. She continued to taste his cock, priming it for the real show that was soon to come, basking in the simple taste of his man-meat. She already couldn't get enough of this boy just from his taste.

Before long a clear drop of Pre formed on his tip. As she was coming back from another long tongue bath of his cock she pressed forward, her plush, pillowy lips finally touching his penis in earnest as they formed themselves around the crown, letting the sizable drop of precum right onto her tongue. She let out an involuntary moan at the taste of his natural taste.

With her lips wrapped around his cock now she pulled back to rest a series of kisses up and down his shaft. Letting him know physically her love and devotion to him, showering his length in intimate, firm presses of her soft, glossy lips. Her eyes closed as she did this, reveling in her worship of her new lover's cock.

Finally she brought his full head into her mouth. Her sky blue eyes looking deeply into his, as much in love as in assurance that she was doing a good job. He reveled in the warmth of her mouth, her copious saliva bathing his dick. She began to bob up and down his length, very slowly getting further and further down his shaft. As she got deep enough to hit the back of her throat, the idle noises she made only got louder and louder.

"Sssk, mfff, mmm, ssskk." She didn't really seem to care about what noises she made or what she looked like on her knees with a teenager's cock in her mouth. Sue was really getting into it. Her moans getting more intense, her pussy getting even wetter somehow. The other girls looked on in fascination as they saw their friend now thoroughly pleasuring Mark's cock.
