It's the Scarlet Witch.

You look to the open door to see a gorgeous redhead standing there. She not in her costume, but you recognize her right away as Wanda Maximoff, a.k.a. the Scarlet Witch, one of the Avengers. She is wearing a dress that hugs her curvy form perfectly.

She looks at you, laying on the bed naked with you cock pointing towards the ceiling and blushes. "Oh my," she gasped as she turn red in the face. "I'm so sorry! I thought that Sue Richards was staying in this room..."

As Wanda mentions Sue's name, you can feel the Invisible Womans pussy muscles clenching around your cock. You can't help but let out a little moan as your invisible lover works your cock.

Wanda looked back down at your cock. Nodding towards the foot long monster, she says, "So... is that your mutant power?"

"You could say that," you say and smile. As you do, Susan begins grinding her hips, making your cock appear to point around in different directions. You see that Wanda's eyes are following it's movement and add, "Sometimes it has a mind of it's own."

"Well, if it's wagging, it must like me," Wanda says as she approaches the bed. "Can I pet it?"

Before you can reply, Susan's invisible fingers pinch your nipples, making you jump a little.
