You hold out and double their pleasure

It takes amazing willpower and self-control, but you manage to not cum. Starfire really tries to squeeze one out of you. You pull out of her slowly and rub your cock against her ass.

"You were quite the amazing lay down," the alien says.

"You mean 'He's an amazing lay,' Star," Raven says, "And it certainly looked like it."

"I appreciate the compliment," Lancer says, "I think it's time to please both of you."

"That sounds great. How could you do that?"

"Friend Raven does raise a good question."

"Let me handle that. Just lay down on the bed next to Raven and I'll take care of everything."

She does what you says, rubbing her naked body up against her friend. Raven just lays there and enjoys it, since she's still bound to the bed by the magically-enhanced ropes.

You walk around to the other side of the bed and move up in front of Raven. She stares at you hungrily, really wanting to have your dick inside of her. You crawl on top of her and line your cock up with her pussy. You push it into her slowly, causing her to moan appreciatively.

"He's a big one, friend Raven. I'm feeling a bit left out now," Starfire says sadly.

"Relax. I've got that taken care of," you say.

You focus your energy and summon your spectral double. He appears on the bed on top of Starfire, confusing the Alien Princess. Before she can say anything, you make it cover her mouth. Before she can raise any concerns, it drives its invisible dick into her pussy.

You start fucking Raven properly, while your invisible double matches your every motion. The luscious Titans are being fucked and loving it!

"I love your cock," Raven says, "Fuck me harder!"

"Me too," Starfire says, "Make your invisible companion pound my pussy cat!"

You and your invisible double do just that, making the girls moan even louder. You reach down and rub Raven's clitoris. Your double copies your movements in unison. You both get the desired results!

"I'm cumming again," Raven says.

"Me too," Starfire says, "I'm cumming hard!"

You strain and strain to not cum. As you focus so hard on this, your invisible double dissipates back into the ether. It's Raven's turn to attempt to milk your cock.

At the last minute, you pull out of her.

"I really want to cum, ladies," you say, "But I'm going to do it my way."

"Alright," Raven says, "What do you have in mind?"
