Strapped In and Strapped On

Batgirl grabs a large strap on dildo and puts it on. She walks back to Supergirl's face, "Open wide." The girl of steel looks up at Batgirl with pleading eyes, but does as she says. Batgirl puts the tip of the huge dildo into the blonde's mouth, "That's a good girl. I need it to be lubed up real good." She grabs Supergirl's head and pushes the dildo deeper until it hits the back of her throat. She then pulls it back before plunging it even further. Batgirl facefucks Supergirl, plunging the cock deeper until its entirely down her throat with every thrust. Supergirl gags continuously as tears drip down her exploited face.

"I think it's lubed up enough." Batgirl says as she pulls the slick dildo from Supergirl's throat. She quickly moves behind Supergirl and positions the fake cock right at the entrance to the blonde's pussy. She grabs Supergirl's ass cheeks and forcefully thrusts the huge dildo into her wet hole, causing her to let out a guttural grunt. As Batgirl pounds Supergirl's pussy she grabs her hair and yanks her head back, continuing to violate her cunt.

Without warning, Batgirl slips the dildo out of Supergirl's pussy and immediately plunges it into her tight ass. Supergirl screams out in a mix of pain and pleasure as Batgirl forcefully pounds her ass. Batgirl vigorously thrusts in and out of Supergirl's tight butt hole, the sound of the girl's primal moans drive her wild. Soon she feels Supergirl's body tense and realizes the girl of steel is once again close to climax.

Batgirl pulls the large dildo from Supergirl's ass, "Do you want to reach orgasm, my beautiful fucktoy?" Batgirl asks, feeling a dominance that she never knew she was capable of.

"....Y-yes." Supergirl replies strenuously.

"Tell me you're mine now and forever and I'll consider giving you a gratifying release, but remember that if you lie the bomb explodes so you'd better mean it."

Supergirl closes her eyes as she gives in to her new role, "I'm yours now and forever....mistress."

Chills permeate through Batgirl's body as she hears those words leave Supergirl's lips. She kneels down and begins feasting on Supergirl's pussy yet again. Batgirl nibbles on Supergirl's sensitive clit, causing the girl to explode in orgasmic bliss. Supergirl's juices coat Batgirl's masked face as she continues to devour her pussy, causing orgasm after orgasm until the girl is completely spent.

Batgirl stands up and walks around to Supergirl's face. She sees the blonde look up at her in a blissful daze and caresses her cheek with a smile, "This was a beautiful start to our new relationship. I can't wait to take you for another spin when we get out of here. Speaking of which...." Batgirl looks to the hologram terminal, "....I think I've succeeded in your little game, Lex."

The terminal lights up with Lex Luthor's appearance, "Yes, it seems you have. I knew you and I shared a similar drive. Supergirl will tell you where to find the key to the next room." The hologram fades. Batgirl looks to her blonde sex toy with expectation.

"It's....inside me." Supergirl blushes and bites her lip. Without a word, Batgirl walks behind Supergirl and kneels once again. She pushes her fingers into Supergirl's pink hole, wiggling them in an attempt to feel the key. "Deeper." Supergirl murmurs. Batgirl slowly pushes her whole hand into Supergirl's pussy, still not finding anything. "Deeper." The blonde moans. Batgirl plunges her arm elbow-deep into Supergirl's pussy causing the Kryptonian to experience an intense orgasm before passing out from exhaustion. Batgirl finally grasps something and carefully pulls it out. Her arm is slick with Supergirl's juices

She opens her hand to see a capsule containing the key. She takes the key from the capsule and gives the **** Supergirl a hard slap on the ass before moving on to the next room.
