His mouth was on her, lips hot and hungry, licking and kissing everywhere. he bent down, catching a breast. All the more aroused for the witness to it all, his hand moved to find her clit, giving her just a little extra zip as he pounded his cock into her. He felt the blood start to flow again, his cock swelling with his seed.
Dex scrambled to his feet, and off toward his bedroom. He was yelling, trying to get Jax to see what was going on, trying to get John to wake up and take control. John would never let this happen, in part because John wasn't queer and because John just wouldn't fall under the spell of an incubus.
Dex returned to the living room with Dresden's blasting rod in hand, and though it pulsed with his will, and the runes glowed down the length, he didn't use it. He wouldn't use it, unless he had no choice, because hitting Thomas would inevitably hit Jax too.
The moment Thomas' climax hit, Dex moved in, using the blasting rod as a bat, knocking Thomas away from Jax. Thomas hit the floor, stunned.
