Chapter 7 by idahoboy

What does Jim call Robin?

Incestuous Identical Twin

"I bet you are." Jim heared a voice from behind him. Looking up in the mirror, he could clearly see a perfect copy of Robin, including her ten-inch cock.

"There you are Rachel!" Robin screamed out between moans. "Can you help me with this stud?"

The new girl stepped up to the side of the sodomizing couple and began to make out with Jim. For a moment he forgot about his craving to suck cock, and just enjoyed sucking on this new girl's tongue. Rachel, for her part, was enjoying her position as she could reach around with one hand and stroke her twin's big dick, and with the other, poke at Jim's own asshole.

Jim was overcome with sensations he had never felt before. In all his years of sucking cock, he had never even played with his asshole. Now this more dominant version of Robin was forcing three fingers in, and he wanted more.

His original plan had been to finish fucking Robin while sucking off her twin, but now he might have other plans.
