Raven can't help herself.

Raven nearly tore the clothes from her body, her eyes never leaving the throbbing cock her friend had developed. "Damn you, Starfire...I feel so fucking DIRTY for wanting this, but..." Raven threw herself to the ground and grabbed the meaty rod with both hands. It was enormous...easily ten inches...maybe eleven. Starfire looked confused.

"Raven? What are you doing? I cannot mate with you in that position." Starfire said, her voice filled with bewilderment. Raven looked up and grinned. Starfire gulped...and her cock lurched. Raven's eyes were filled with lust...and they had gone from purple to red. "Let me show you a trick we have here on Earth, Star. I just have to have this cock in my mouth..." That said, Raven opened wide and slipped Starfire's new appendage in. Starfire bit her lip.

"X'hal, Raven! This...mmm...this is most delightful..." Raven moaned, fingering herself as she bobbed her head along the shaft. What she couldn't suck on, her hand stroked. Part of her was screaming for her to stop this. ...a part that was getting quieter and quieter. The rest of her was loving every second of it. Soon the protesting voice was gone and all Raven wanted to do was suck her friend off...then get fucked. Oh, that thought drove her wild. Starfire put her hand on the back of Raven's head and started to thrust in time to Raven's bobbing.

"Oooh! Oh, X'hal...your mouth is so warm...so wet!" She sputtered something Raven couldn't understand before tensing. Raven felt warm fluid gush out and she swallowed all she could, the rest spilling from her lips and running down her chin. Starfire stumbled back, panting. Raven took a few deep breaths of her own, laying back and fingering herself in earnest.

"What are you waiting for, Starfire? Fuck me...stick that cock in my wet hole!" Raven demanded. Starfire's cock was stiff again in seconds and she smiled. "I knew I had made a wise choice with you, Raven." "Stop talking and fuck me! Azar, you did this to me, now fix it! Fill me up!"
