Jen briefly thought about just reducing Kyle to just a head for her to use, but discarded that idea almost immediately. Though admittedly cute - damn the curse for turning her into a lesbian - the last thing Jen needed was to look anything like the one that had changed her in the first place. Also, she didn't especially fancy the whole 'nerdy girl' look.
An idea hit her, and she put it into motion.
Kyle's limbs all detached simultaneously, causing the already distraught-looking girl to fall forward, face down onto her newly severed legs. She wriggled her torso trying to right herself but only managed to flop over onto her back on the bathroom floor.
Kyle felt her shoulders and hips started tingling as her torso grew a new vagina where each of her limbs used to be attached. Consequently, on each of her detached limbs, where they used to connect to her body, she grew an abnormally large and feminine-looking penis-like appendage.
If Jen still had a head she would have frowned a little at this, but the curse's dare she was under would not let her add any truly male parts onto her victims. Still, they were similar enough to dicks to suit her purposes so she let it go.
Kyle looked up at Jen once her transformation was complete. "What have you done to me?" she demanded.
Jen just laughed and said, "Payback's a bitch isn't it? Since you essentially stole my head and turned me into some kind of succubus, I decided that you can go fuck yourself. You'll have to, if you want to use your arms or legs."
"You bitch!" said Kyle, but was silenced by Jen.
"Now now Kyle, when we are alone you will call me your Mistress"
Kyle frowned, "I don't know what you're talking about bi...Mistriss" she blurted out, then shut up immediately.
"That's better." said Jen, "I bet you're wishing you didn't force me to make anyone I transform subservient to me now, huh? Now hold still and I'll reassemble you"
Kyle felt himself freeze up, unable to move a muscle. Jen went about putting her new toy back together, taking each limb in turn and stroking its pseudopenis until it became rigid, then jammed it into its corresponding pussy on Kyle's body. The joining points of the new girl's limbs were incredibly obvious even from afar, but their locations were such that Kyle's clothing would easily cover them.
As they were attached, Kyle tentatively tried moving her altered arms. Every movement he made sent jolts of pleasure through the penis / vagina combo that was now his shoulder socket. Hell, she clenched her fist and nearly came!
Finished, Jen stood up and got dressed. "Now Kyle I made your new... Enhancements extra sensitive so try your best not to cum or your limbs might shoot off again. As for orders, I want you to come to my house this evening with at least one other girl to add to my... collection." Jen laughed again and left the bathroom, leaving the dazed Kyle alone to try to figure out how to get up without the movements causing his leg-cocks to ejaculate and have her fall over again.
