Wrong place, right time

You expect to find yourself back in Olivia's mansion after teleporting out of Black Widow's car, but you immediately notice that you're not there. You hold your breath as you look around and it takes you a few seconds to realize where you're standing. It's 1 of the rooms at the Avenger's training facility that you had seen in a magazine. After spending the day with Black Widow and doing a lot of Avengers-related things, your mind must have still been thinking about the Avengers and that's why you've accidentally teleported here.

You're standing in 1 of the private rooms for the Avengers to stay here and the curtains are drawn so it's a little dark. However, right in front of you, there is a person with their back to you standing by the windows and peering out through the small gap where the curtains part. You easily recognize the person from her auburn hair and signature red coat.

You gasp quietly when you realize you're in the presence of a powerful Avenger, which gives away your presence and the Wanda Maximoff turns around. You feel the contours of your face and body shift, a familiar feeling from before when you had changed into Tony Stark.

"Vision! You almost scared me! How many times have I told you to use the door??" Wanda says. You glance at your reflection on a nearby shiny surface and you see that you're green and red all over. You've morphed into the appearance of Vision, who everyone associates with Wanda.

"Yes... Sorry about that..." you say, trying to imitate the way Vision speaks. You notice Wanda looks troubled. "Is... something wrong, Wanda?" you ask.

Wanda shakes her head at first, then she changes her mind and nods, then she looks unsure. She steps away from the windows and closer to you, allowing you a better view of her hourglass figure under the coat. She's wearing black leather pants and a matching black blouse.

"What is it, Wanda? You can tell me," you say.

Wanda blushes and looks hesitant to speak. You go closer to her until you're standing right in front of her and you lift your right hand and gently caress her left cheek. "Wanda, you can tell me," you say softly.

"It's just..."

"What?"

"I feel so lonely... I know we hang out all the time and I love spending time with you, but I just wish we could... you know..." Wanda says, biting her lower lip and looking sexy.

The robotic Vision might not understand what she means, but you certainly do. "Oh," you say, slightly taken aback although you're not surprised that a woman like Wanda has needs. Then, you have an idea.

"Well, that can be remedied," you say as you gulp and look down, concentrating hard in your head, hoping that the effects of the strange blood will work as you hope. Slowly, at the place where your crotch was previously flat and lacking in anything, a fully erect cock that resembles your own 1 forms and sticks out of your body. The shaft is green while the tip of the cock is red, matching the color themes of Vision's body.

"Oh my god! Is that a..." Wanda says, looking down too.

"Yes it is," you answer.

Wanda's eyes go wide and she pauses for a moment before she moves her hands and suddenly all her clothes are ripped off her body and she's completely naked. She makes your cape fly across the room too and she takes your hands and leads you towards the bed nearby. She falls back onto the bed when she gets there, pulling you down and on top of her and your lips instantly mash together while you climb between her legs. Wanda eagerly grabs your cock and guides it into her pussy without much fanfare or waiting, likely horny as hell and having waited for this for a long time.

"Oh my god!!!" Wanda moans as you enter her and you hold in your own exclamation since that would be uncharacteristic of Vision. You give Wanda a few seconds to get used to you being inside her before you start to move your hips and fuck her. Her pussy is really tight and almost seems to suck you in on each thrust, and as for you, it feels like real sex to you even though you're not sure what your cock is made of right now.

"It feels so real! I'm assuming!" Wanda moans.

"You're assuming?" you ask with a raised eyebrow.

Wanda smiles. "Well it is my first 1. I wouldn't know what to compare it to, but it feels amazing. Better than any dildo I've owned for sure," she gasps, wrapping her arms around you and urging you to keep fucking her. You're happy to do so without complaint and it only takes a minute or so before the sex-deprived Avenger has her first orgasm with you, although you just keep fucking her like normal and her moans only get more sensual and loud.

It might be the fact that you've already cum today or perhaps you've inherited Vision's stamina, but you're able to keep fucking Wanda almost mechanically and continuously for a very long time like that, and it's not until her 4th orgasm when you cum too. As you plunge your cock deep in her pussy and cum, Wanda holds your face in her hands and looks blissful and confused at the same time.

"Are you... cumming??" she says, feeling the warm stream of cum in her.

"Yes, in a manner of speak. I'll explain some other time," you say. Wanda smiles and nods, willing to accept your flimsy explanation for now and she lays there underneath you, panting in exhaustion.
