Jen had a naughty idea. A very, very naughty idea. Deep in her most twisted fantasies, she had thought about fucking Zoe. As Jon, she had a collection of incest porn, and used it to vicariously live out the taboo. But now, with the stone, a great deal more was possible...
"I wish that, for the next month, Zoe and I were incestuous lesbian lovers," she wished, and the stone flashed. Looking around, she could see her room was now slightly different. Her bed was replaced with a larger one, and there was an extra nightstand.
"Hey, lovergirl," chimed a voice behind her. Jen turned around, and there was Zoe, clad in sexy black lingerie. She approached Jen and pulled her into a close embrace, kissing her with tongue. Jen's heart fluttered as she led them to the bed, unbuttoning her whalebone corset as she went.
"Zoe..." Jen started, but was cut off as Zoe put a finger to her lips. "I think it's my turn to try the strap-on this time," she seductively whispered as she lifted a black phallus from her nightstand drawer. "Lay back and spread em, sis!"

Zoe climbed on top and started thrusting into her. Jen let out a squeal as the rubber cock slid between her nether lips, but soon was bucking against it, generating friction against her delicate clitoris.
"Zoe.. Don't! Stop!" she panted as she approached climax. Her pussy gushed lube, soaking a wet spot into the sheets. With a primal scream, Jen gazzed, and Zoe came simultaneously.
The two sisters lay there panting for several minutes. It was the best sex Jen had ever had. "This is going to be an interesting month," she muttered to herself as she spooned her gothic twin...
