Invisible man

The moment you walk in and see that the woman at the front desk has her head down, you activate your invisibility ring. You're still thinking about this morning when you had tried to look for Hannah, the girl you have fucked in the dressing room while invisible, and you feel that you need to recreate that experience in order to get over your frustrations. The woman looks up, having heard the door open, and looks puzzled, but then goes back to what she was doing before, and you walk pass her desk into the gym.

You then walk down the hallway into the main gym area that's pretty large and open, and all visible from the street. It's rather crowded at this time and you smell the sourness of sweat in the air. It's a good thing the ventilation is blasting cool, fresh air constantly. The employees are all wearing the same light blue polos.

You glance over at the woman you had seen from outside and she's still running at full speed and doesn't look like she's going to stop anytime soon, so you take your time and walk around, looking at the sweaty people in the gym. About half are men, and while some of the women are pretty hot, you've already had your eye set on the woman in the pink sports bra. You wander to the back when the showers are and you enter the women's side. It's a huge locker/shower area where there are private stalls with translucent glass doors for privacy and you can hear the loud running of water from the occupied stalls. You see a chubby woman in her 30s step out of a stall with a towel tucked under her arms and you wait a while to see if she'll lower it, but there several other women in various stages of undress and she seems too shy to open the towel and you quickly lose interest.

You return outside where you see the woman you had your eye on has dismounted the treadmill and she's walking towards you, heading into the showers, so you step aside and follow her as she passes you.

Once inside, she heads to a locker and opens it, before starting to strip off her wet workout clothes. The sports bra comes off first, and her breasts are not big, maybe a 32B, but they're perky and perfect for her slim body. Then she takes off her shorts and panties, and her ass sticks up like it defies gravity. You can see the tanlines of a bikini, but apart from that, she's quite a perfect specimen. There's a tiny strip of hair right above her pussy as she bends over to stuff her clothes into a gym bag and grab a towel from a stack of them in the middle of the room. She then forgets to lock her locker as she heads to the available stall on the far right side of the showers.

You then quickly disrobe and stuff your clothes into her locker, but before you go to join her, you rummage through her bag for her purse and find her ID. Her name is Kerry Fox and she's 27. You also find a stack of business cards with her name on them. She's a senior associate at an advertising firm on Madison Ave and you slip one of the cards into your pockets and close the locker.

The water is running when you approach the stall and you open it and enter. Luckily, there are no locks on the shower and the door is just for privacy. Kerry's back is to you and you can see that she has her right hand between her legs and it appears that she might be touching herself. She turns around when she hears the door open and close and she looks through you, confused at what happened.

Quickly, you use your finger to write on the steam-covered translucent glass.

"Hello :-)" you write.

Kerry gasps and retreats under the pouring water. Her right hand is still on her pussy, though she shifts it to cover it up now.

"Shhh....." you write below and you can see the look of horror on Kerry's face as she uses her other hand to cover her mouth and stop herself from screaming.

"Won't hurt you if you don't scream and do what I want. Nod." You write. You're running out of space and you have to wait for the glass to steam up again to write more, but you see Kerry nod profusely. Slowly, you walk over to her, until she can see the water bouncing off your invisible form and she realizes that there's someone standing right in front of her. She flinches when you place your hands on her shoulders and has to stifle a scream, but she calms down after you whisper, "shhhh...."

Next, you gently pull her hand away from her mouth and lean in to kiss her, softly at first, then harder when she doesn't resist. You continue kissing her for a long time, placing your hands on her hips, and after a while you can feel her kissing you back. When you pull away slightly, you see her open her eyes that she must have closed while kissing.

"What are you? A ghost?" Kerry whispers.

"I'm the invisible man," you reply and you pry her right hand away from her pussy and place it on your cock, wrapping her nimble fingers around it.

Kerry gasps as she feels how big your erection is. "Oh my god," she remarks as her hand moves up and down your cock to examine it, using both hands to touch it, fondle your balls, then creep up your body and feel you all over to make sure you're a real man. She then leans her face toward and puckers her lips, moving it around and searching for yours, and you give her another kiss.

"Are you here to..."

"Fuck you?"

Kerry blushes and nods.

"Yes," you respond and you activate your super strength ring as well. She's pretty petite and you shouldn't have any difficult lifting her up, but this way it's easier and you focus on what's important rather than worry about dropping her. "Were you masturbating?" you ask.

"...yes."

"When was the last time you had sex?"

"A few months ago."

"With a boyfriend?"

"No."

"Who was it? Tell me more."

"It was one of the partners at my firm. I was one of the four candidates for a promotion and he said he would give it to me during the interview if I let him fuck me."

"And you did it right then?"

"Yes. He bent me over the table. It only lasted a couple of minutes."

"Did he fuck the other candidates too? Did you get the promotion?"

"No. Two of them were men and the other woman was fat. Yes, I got the promotion."

"What about before that? When was the last time you had sex before that and tell me about it."

"It was a few weeks before that with someone who goes to the gym here. Carl. He's very muscular and comes here to lift weights a lot and he asked me out. He took me to dinner and then we went back to his place and I spent the night."

"Why didn't you see him again?"

"He had a small dick."

You chuckle and Kerry giggles quietly too.

"Is mine bigger?" you ask, knowing the answer.

Kerry's hands move down your torso to your cock again, and she strokes it with both hands. "Oh yeah..."

You let her give you a handjob for a few moments before moving on. Your hands slide down her waist to her ass cheeks, supporting them and you say, "Put your hands around my neck and hop on."

She's strangely very trusting of an invisible naked man in the shower with her, and Kerry locks her hands behind your neck and hops up with your hands on her ass giving her a boost, and just like that her breasts are sticking into your face. You playfully suck on one of her nipples, while she lowers herself until she can feel your cock poking at her and Kerry reaches down to guide it to her pussy and sinks down onto it.

"Oh! God this is huge," she exclaims almost too loudly as you feel her pussy wrapping around your cock and adjusting to its size. Once she's comfortable, you start bouncing her up and down your cock and she grabs your face and starts kissing you furiously as you fuck her.

After a while, Kerry starts moaning, "Oh god, oh god, oh god" repeatedly and you realize she's having orgasm as she clings on tightly to you and throws her head back. She struggles to hang on to you as her body spams in waves of pleasure while you keep fucking her, bouncing her up and down faster until you feel the explosion in your loins as you start to cum inside her just as her orgasm subsides.

"Hey! No masturbating in there! That's disgusting!" you hear someone outside yell and you and Kerry share a giggle as you hold onto each other tight.

You help Kerry off your softening cock and put her down on the ground and kiss her again.

"I needed that," she says with a big smile on her face.

"Me too."
