On their faces!

The two superheroines don't answer the question directly, but ask you to pull out so they can roll over. They both end up on their backs next to you each other. They look up at your dick.

You take the hint and start to jack off, your cock about ready for release.

Below you, the pair cross arms and start to rub each other's pussies. They are giving you an extra show and also pleasing themselves in the process.

You cum moments later, shooting your lead on their pretty faces. They don't stop fingering each other.

As they cum from each other's fingers one last time, the pair lean forward and suck both sides of your wilting cock.

They suddenly stop, seemingly upset about something. You look down confused.

"We lost control a little there," Ice says, "We emitted some low-level heat and cold."
"Yeah, are you alright?!?"
"Yeah, I'm fine," you reply, "I didn't feel a thing. Well, besides the obvious."

As you all clean up, you theorize that your Nanites must now be giving you a low-level heat and cold resistance. Those things learn fast from Superheroine juices! You're getting slightly-more powerful the more pussy you get around here.

After a quiet day off and a stake-out with Elongated Man that yielded nothing, you wake up the next evening from a nap. You get dressed casually and go for some coffee.

All of a sudden, a pair of strong hands grab you and pull you into private room.

You see Wonder Woman and Power Girl there, dressed in their famous uniforms.

"One last reward for good behavior," Wonder Woman says.
"That and I have something to prove," Power Girl adds.

Before you can ask for more answers, you see something amazing...
