Something tickled beneath Mark's nose. He tried swatting it, but it wouldn't go away. It felt like a bug. He opened eyes to Becky's smiling face. She had been tickling his nose with a bit of her own hair. "What the fuck?"

Becky gently pressed her finger to his lips. Then she turned the finger to a hook, beckoning Mark out of bed. Merry was asleep next to him. Reflexively he got out of bed and followed the siren. She was wearing the flyaway nightie that Elizabeth bought.

She was gorgeous, she was sensual, and she was...just out of reach. Springing on tiptoe, she led the naked, sleepy man down the hallway. She stopped at the door to Suzanne's room and opened it. Suzanne, not Suzy, stood on her knees on her bed wearing the same white cotton chemise.

"Good evening my lord."

Becky handed him a silver flagon of more wine. "Suzanne?"

"Fear not, my lord. It is I, you faithful, Suzy." To emphasize her point she changed into Suzy and back again. "It is just that you and Mistress Merry had all the fun this night and I thought I could make things up to you a bit."

"More illusion?"

"No, my lord. We Shidhe can shape to please thee." She gave him a smile that would turn mud to steel. "This is what you wanted isn't? Here? In her room, in this cotton chemise?" She bent her arms and lifted her curly hair with her forearms. This had the effect of raising her breast level and exposing her neck. Suzy-Suzanne appreciated herself in her vanity's mirror. "Same nice, big butt, same huge tits. Hmm. You wanted my hair a bit browner, auburn, isn't my lord?" Her hair simmered and turned a warm chestnut, a perfect auburn."

"My favorite color. How did you know?" He gulped the wine.

"We know all the things we need to make you happy." Suzy-Suzanne slipped the left string off her shoulder, exposed her breast and extended her arms. "Now come here and have the evening we should have had."

Becky took the flagon back and Mark walked slowly to the beckoning nymph. He bent his head and kissed her breast. She threw her head back, cradled his head and cooed in bliss. "Ooooo. That is perfect. Little softer. Swirl your tongue, yesss. You are so good. Now lie back."

Mark lay back and Suzanne licked it like she was dying of thirst and it was the last icicle on earth. It was already halfway hard so she didn't need to lube it with mucus long.

Suzy-Suzanne straddled him with his knees, pulling her chemise's skirt forward. "Shhh. Just lay there and let big sister take care of everything." Under his skirt, her long cool fingers curled around his pole. "Oh, little brother is so hard. He wants to fuck s much. What can big sister do to help? Can big sister fuck little brother, will that help?"

"Yes, fuck me."

She looked down with Suzanne's face twisted in desire, "I love it when you talk dirty to me, little brother, makes big sister's pussy all wet, yes it does." Suzy-Suzanne twirled his head on her clit. "Feel how wet big sister is for little brother? How much she wants little brother's dick inside her?"

Slowly she lowered herself on his sex skewer. At little intervals she rose up and hissed, like she was lowering herself into a bathtub of water that was a little too hot. Finally, she engulfed him. She was incredibly tight, along his whole length. Her pussy squeezed its new tenant like a long, buttery fist. Mark could feel its pulse.

She lowered her other string, took Mark's hands and placed them on her globes. "Pinch them. That's what big sister likes best, pinch her nipples hard while she rides a big, fat cock. I'll do the rest, just relax."

Mark complied. Suzy-Suzanne rode him like a rodeo cowgirl. She whipped her auburn ringlets forward, they smelled like flowers. She hunched her back and humped up and down. Mark could feel the smooth cheeks of her ample ass pressing against his thighs.

"Oh, this is so wrong. I shouldn't fuck my little brother. But it feels so good and big sister loves him so much."

Mark was in awe of this Shidhe's knowledge, this was his fantasy come to life. And her pussy was like a living thing, it squeezed him all at one, one place at a time, rippled up and down its length, it even flicked the head like a tongue. Her secretions ran down his thighs in a sheet.

"You feel so good fucking me little brother. Oh, this is so wrong. Does it feel good to you too, little brother."

"Yes, oh, yes. Fuck me Suzanne. Fuck me."

"Them come inside me little brother. Fill your sister's womb with our families seed." Suzy-Suzanne increased her pace. Her beloved was about to come and she wanted him to enjoy it. Little did Mark know that he was lighting the fuse to an explosive event that could destroy him.

With a last, sustained thrust, Mark ejaculated into his sister's pussy. Mark was expecting Suzy-Suzanne to come to, after all he had programmed it, but was wasn't expecting the violence with which the Shidhe came.

Suzy-Suzanne screamed loud and long. Her eyes rolled over into the back of her head. Her eyelids fluttered and her lips made little smacks. He pussy constricted Mark's cock, like and electrical current had just hit it. Suzy flopped on his impaling cock, like a gaffed fish. Becky's eyes went wide in surprise.

Still half dressed in the chemise, Suzy reverted to elfin form and collapsed into a stupor. She was only half-conscious. Her loins reflexively quivered on Mark's phallus.

"By the moon! What did you do to her?" Becky rushed to her sister's side and cradled Suzy as she dismounted her. Suzy had a smile that went ear to ear. She spoke happy mumblings.

"Nothing. Maybe she had an orgasm."

"A what?"

"An orgasm."

Becky used Elizabeth's memories. "Female ejaculation? Impossible. Shidhe women do not get such things."

"Well I guess they do now." They both stared at the prostrate, content figure on the ground. Suzy was panting like a kitten. Mark lifted her on to her bed. "She seems fine. I am going to sleep. Let me know if she gets worse."

Mark stopped by his bathroom pee, take a drink of water and wash off his cock. It was sticky and uncomfortable. As he slid into bed, Merry stirred. "I heard a scream. Suzy?"

"Mm-hmm."

"Did you have sex with her?"

Mark did not lie. He figured all the rules were broken in the illusionary forest. "I left her on the floor. I think she was comatose."

"Good." She snuggled up to him. The lovers spooned and slept.
