Chapter Text
Having the ability to turn invisible had a plethora of uses, something which Susan (Sue) Storm knew very well since that fateful day in space when she and the other members of the Fantastic Four were bombarded by Cosmic Rays. Since the day she had learned of her abilities, and the many days since where she has mastered them, Sue has found many situations where her gifts were useful. Not just invisibility either as her powers allowed her to create force fields and even invisible surfaces, just to name two other capabilities. Indeed, Susan has made use of her powers in many ways...
But never would she thought about using them for sexual gratification.
One downside to her abilities was that Susan wasn't able to block sounds or when she was invisible so under cases of stealthy being necessary she would have to keep her voice down or else she could be caught. In her defence though; you weren't exactly helping the situation when you were thrusting so intently into Susan's tight pussy as she not only had to suppress her voice but maintain focus unless you both wanted dunking into the water of the lake in Central Park.
The both of you were naked, standing on an invisible platform that Sue created above the water of the small lake. There was another invisible surface she had cast and which she was bent across whilst her hands trembled to maintain the field that blocked the two of you from being seen, all as Susan tried to suppress her moans as she felt your cock stretching her walls. The clapping sound of colliding skin from your thrusts were thankfully drowned out by the hubbub of all the people in the area.
"S-slow,down, oh, I can b-barely, maintain, ah, focus" Sue struggled to say as beads of sweat were spread across her forehead. She was trying so hard not to moan loudly as well as keeping up the barriers that kept you from dropping in the water or being seen, but your thrusts were sending sparks of pleasure up her spine as you had her bent over in front of you. Her breasts were pressed against the invisible surface she was braced over, body rocking against it as Susan Storm was finding it very difficult to control herself.
In response to her words of warning you just chuckled and started thrusting faster, harder too, as you leaned to Susan's ear. "But this was your idea" you teased and Susan bit her lip, feeling her already flushed cheeks burn hotter as she whispered for you to shut up. You just chuckled though as you watched the expressions of pleasure force their ways onto Sue's face as you gave her the pleasure she wanted.
It was true that this was Susan's idea, the whole thing was her idea. It stemmed from a wet dream she had, one where she was wandering the streets of New York naked but invisible. In the dream she knew that if her powers cut short then people would see her, so many people, and though she did her best to keep her powers up she couldn't help but be aroused by the idea. It led to her waking up wet, leaking her liquid arousal as she was initially embarrassed about having such an erotic dream.
Not that it stopped her from touching herself to the thought of it. Not that it stopped her from going through with it that very same day, wandering the streets with nothing keeping her hidden but her powers. Susan had to make sure not to bump into anyone as she walked, flushed in the face until she got back home and she masturbated the tension away again.
Several escapades later and Sue wanted to do more, and such was when you came in as she enlisted your help to bring her fantasies to life after another erotic dream of her getting fucked out in the open but hidden with her powers. She came to you with the request, one you were initially surprised by considering she came to you when you were in the shower. You were a little uncertain as well but Susan made a very persuasive argument by giving you a blowjob whilst she was invisible, the steam and water of the shower outlining her fantastic figure. It gave you a nice idea of what you'd be in for if you did what she requested, and how could you say no after that?
Fast forward a few days later when you were both free and Susan led you by the hand to Central Park, concealing both of you with her powers as she insisted on a naked walk. Then she used her powers to create a path to the centre of the first lake you came upon and things got going.
Now you were hunching over Susan, pressing against her back as she was bent over an invisible surface. You pushed on her shoulder as you slammed your hips into her ass, plunging your cock deep into her cunt as you fucked her. This would have made her cry out from pleasure from how deep you went had you not stuck a finger into her mouth to suck on, which she did sloppily as her focus was split...not that she could focus.
"Oh god, this feels...so good!" Susan thought to herself, enjoying it all even as she was so scrambled with her thoughts. She had came twice already by now; both of the orgasms were fucked out of her as you got strajght to business without foreplay, she was wet enough already from a perverted eagerness after all and had you shove your cock into her from the get go. It felt so good, she was on the verge of another orgasm as she sucked on your finger before feeling her head being tilted back as you pushed your tongue into her mouth.
At first, Susan thought it was just for the sake of a kiss, but then you pulled her upright and reached down to lift her feet off the invisible surface. This let Susan decrease how much she had to split her focus, which she appreciated the chance for, but then you practically folded her in half, locking your hands behind her head as her legs were over her shoulders. You lifted Susan up into a Full-Nelson lock and bounced her on your cock, plunging into spots you shouldn't be reaching as it made her cum instantly. Thankfully her voice failed her as she would have surely drawn some eyes in your direction if it didn't, especially as you slammed your cock upwards each time you dropped her hips.
"He's so intense! I-I-I, I don't know if I c-can...hold out much l-longer" Susan barely completed her thoughts as she felt your cock plunging balls deep inside her with each motion, slamming against her G-spot, your balls smacking against her pussy each time. The pleasure was mind numbing, Susan's tongue flopped out of her mouth as her eyes were hazy and crossed.
She was already about to cum again and that should have been embarrassing, but then she felt you throb inside her.
"Sue" you grunted into her ear and Susan barely managed the strength to tilt her head back and lock her lips with yours as you brought her down onto your cock once more, sending the both of you spiralling into a mutual climax. How Susan managed to sustain the surface you were standing on was nothing but a testament to her powers as she felt your hot creampie fill her cunt as she splashed her own juices one more time whilst lazily making out with you.
The afterglow of the mutual orgasm was amazing but faded too soon as Susan instead felt her focus return, even if her legs felt weak as you set her feet onto the invisible surface you stood upon. She collapsed to her knees the second her feet hit the ground, separating your bodies for your cum to leak out of her as she panted and gasped for breath. Susan was still trembling from the bliss that had faded by now, her body starting to feel the aches of being taken so roughly but it felt so good.
"So, was it good for you?" You asked and Susan looked back at you before laughing. "Good? That was fantastic!" She managed to praise without being too loud and you chuckled, replying that it was definitely fun. "I hope it was as good as you hoped for" you mused as you helped Susan to stand up and she replied that it was better than she could have imagined.
Cupping your face, Susan pecked your lips, thanking you for doing this for her and you nodded. "You made a very compelling argument for it" you replied before noticing the quake in Susan's legs as well as the load of cum that was spilling down her thighs. "People may wonder why semen is suddenly appearing on the floor if we walk back now, maybe we shouldn't have come here without clothes" you said but Sue replied that there was no need to worry about that as she used her powers to create a barrier that prevented your cum from spilling.
"Now I just need to focus on that spot until we get back, but my legs are still weak" she said before gasping as you lifted her up into your arms. "Problem solved" you mused and Sue laughed before pecking your cheek as you carried her back to the Baxter building, letting her focus on not letting your mixed cum spill as you carried her.
You carried Susan to the shower so she could clean up and you went to leave her there but she caught your hand, offering for you to join her. "I would also like to ask; can we do that again sometime?" She requested and you laughed, answering that you may be willing to do this again and Susan let a smirk creep onto her lips as she suddenly disappeared from view as the shower water ran and you were pushed up against the wall as the water rained down against the invisible skin of the Invisible Woman.
"Allow me to make another compelling argument then" you heard Sue whisper before there was a wet warmth around your cock and you looked down. The shower water and rising steam outlined Sue's body as she sucked your cock, tasting herself on you still as she reached an invisible hand between her invisible legs to finger her invisible pussy which leaked your cum.
As you both showered, Susan made another compelling argument and you agreed to indulge her perverted interests again when you next had the chance. For now though you enjoyed the fantastic blowjob she gave as you thought about how fun it was to do something so risky as what Sue had suggested you do. You thought about when you would next have the chance and discussed with Sue the next date.
You both looked forward to the next time you had fun in plain sight.
