Taking a deep breath, Vaggie focused on her magic. Her chest heaved as she concentrated, and finally, with a glowing sensation spreading through her body, she felt a new appendage growing between her legs. A thick, impossibly long cock emerged from her vulva, easily matching the size of your own. Panting from exertion and excitement, she looked down at her transformed self with amazement.

"Do you like it?" she asked breathlessly, raising her new cock for you to see.

Vaggie moaned loudly as you thrust your cock inside her pussy and jerked on her newly grown cock. The sensation of being filled by both of you was overwhelmingly pleasurable, and she found herself unable to contain her lustful cries. Her body arched off the bed, meeting yours stroke for stroke as their combined rhythm drove them both closer to orgasm.
