Zoe was no less shocking than Jon's mom or Karyn. First, her entire body from the hips down -- butt, pussy, knees, feet, and all -- was backwards! Second, her arms were attached to her hips, and not to her shoulders! The tips of her shoulders simply blended into her sides! And she, like her mother, was completely nonplussed and naked!
"Jon, my hands are dirty. Give Zoe a hand, would you?" Jon's mother asked. "Jon? Jon? Are you hiding under that sheet?"
"Uh, yeah," Jon mumbled.
"Whadya, suddenly bashful?" Zoe teased as she sat on the edge of Jon's bed. It was enormously weird to see her bent knees pointing away from the bed and her face pointing toward it. Then, with no motion above the waist, she pulled away Jon's sheet!
Jon was pretty sure what had happened to him, but he'd been trying to avoid looking at it. That hadn't stopped him, though, from using his new lower limbs to stroke himself. All of which Zoe revealed when she pulled back the sheet.
"I'da done that for you, you know," Zoe remarked as she eyed Jon's erection. "Are your upper hands dry, at least?"
"Uh, yeah, pretty much," said Jon as he wiped the lower ones on the sheets.
"Well, here then," Zoe urged as she handed him the new nose ring.
"Why me?" Jon complained.
"You know I can't reach my face," Zoe asserted. "C'mon; I help you often enough. And get closer."
With some difficulty Jon used his lower arms to shuffle across the sheets and sit in front of Zoe. If, indeed, sit was still the proper word. Jon felt terribly strange using a second pair of arms rather than his legs to balance.
Jon began looking for the clip that secured Zoe's nose ring, then jumped when she gently grabbed his cock. "What are you doing?" Jon asked.
"If you can't figure that out, I'm not going to tell you," Zoe replied, then she intensified her efforts. Jon never saw it cumming. He just wasn't used to sitting and facing a girl, especially his sister, whose face, tits, and butt pointed forward, but whose legs and knees pointed backwards, neatly out of the way. Or one who had no arms on her shoulders. Or one who had arms on her hips.
"You're wobbling," Zoe informed Jon after wrinkling her nose. "Scoot forward and hold my thighs and shoulders."
"Are you sure..." Jon began to ask, then his mother told him, "Go ahead, dear. I'm helping Karyn with her hair."
Jon felt terribly strange grasping Zoe's armless shoulders. He felt even stranger using his lower hands for anything, and especially for reaching around her hips and inside her thighs. Zoe, however, apparently found nothing strange about stroking Jon's cock. She simply wiped it with a sheet corner and kept on stroking.
"Do I have to spell everything out for you?" Zoe asked harshly after Jon had cum again. "You know I can't reach myself."
"Go on, dear," Jon's mother told him.
After that, and since Jon had already cum twice, Zoe moved her arms around Jon's waist and pulled him fully against her. Jon felt his chest pressing against her tits and his cock pressing against her butt crack. Then his new lower hands felt dampness in her pussy. Jon began fingering Zoe's lips, her hole, and her clitty, then a few minutes later she came.
Jon kept fingering Zoe until she was finished, then he tried to pull away. Zoe still had him by the waist, though. "Sorry, bro," she explained, "but you still haven't finished that nose ring job."
"That's nice for the two of you to help each other," Jon's mother remarked as he finished inserting Zoe's nose ring. "Karyn, are you giving Jon a ride to school this morning?"
