"Wait a minute Cassie, what is this you're rubbing at me?" Rachel asked.
"Do you really want to know?" Cassie asked.
"Of course I want to know." Rachel said. Then Rachel felt Cassie take her hands and guide her to something hard. It was something with a cylindrical shape. Touching further down she found her something loose that raised some suspicion in her, making her search the other end of this object. Finding the other end she was sure what it was and said. "I can't believe it, you have a cock and balls, and they are huge. Don't tell me you became a...."
"A shemale. I became one and never felt better." Cassie interrupted Rachel "And I got hard thinking about you."
Rachel then started to undress and said "I can not deny it, touching your cock I ended up getting horny and also want to feel it inside me." Then she lay on the bed and spread her legs waiting for Cassie.
Then Cassie began to fuck Rachel slowly, slowly increasing her pace.
Rachel looked at Cassie fucking her, forgetting that her friend was invisible. Even so she was not disappointed with what she saw. Right in front of her was a mirror that allowed her to see her pussy opened by the invisible cock. With this scene in mind she reached orgasm.
Cassie also came, planting her seed in Rachel's womb. Then she took her dick from Rachel's pussy, still cumming. Cassie's cum was invisible too and Rachel could only feel it when she was hit in the chest and in the face.
When their orgasm was over Rachel lay motionless in bed. Then she felt the mattress move and knew it was Cassie who lay beside her.
Cassie then kissed Rachel on the cheek and said, "Much better than I expected."
