Eric and his 8-legged humantaur girlfriend Lisa, her second identical body Lisa, and her third identical body Lisa, decided to move from the cold linoleum floors of the kitchen to the much nicer carpet of the living room. Eric sat at one end of the big sofa and gestured for Lisa to sit with him.
One of Lisa's bodies did her best to sit on the sofa. Due to her length, she had to drape her final taur segment across the armrest. The downward weight of her body being transferred through the 24 breasts lining the bottom of her taur segments had a visible effect on her, causing her to bite her lip and making her face flush. Eric happily accepted her attempt at an 8 armed cuddle.
Lisa walked her other 2 bodies into the center of the room, and started to inspect her new forms more closely. Eric and the Lisa on the sofa watched. All 3 Lisas spoke simultaneously, "This is so surreal. I'm in 3 places."
The two Lisas in the center of the room slowly reached up with their many arms and lightly touched the breasts on the other Lisa's torso. The touch quickly turned into caresses and gropes. Moans of pleasure escaped all 3 mouths.
Satisfied with her initial findings, both pairs of lowest arms dropped lower until they found the other body's genitals. Her penises were already mostly erect, and her vaginas were visibly moist, even from the couch.
One hand stroked each penis, and one teased each vagina. More gasps escaped from her mouths, this time only from the bodies in the center of the room. The Lisa sitting on the couch turned to Eric and proudly whispered, "I didn't know you were so okay with other guy's dicks."
Eric couldn't break his eyes away from his girlfriend(s) pleasuring herself in front of him, "Not other guys. Only yours."
"Well then, I hope you enjoy this even a fraction as much as I think I will" 2 more hands reached out to caress each of her penises, making them grow visibly harder and even bigger. Grabbing them by their base, Lisa tilted her groins slightly so her dicks pointed towards Eric. One by one she moved more hands from groping her breasts to stroking her penises.
Eric was completely mesmerized by the hand jobs he was watching his girlfriend give herself. He was already hard just from watching all 3 of her walk around naked, but this was almost torture. Suddenly he felt a hand grab his penis at the base, just like he had seen Lisa do to herself. He looked down to see she had unbuttoned his shorts while he was distracted, releasing his erect penis, and was now giving him a hand job with 4 hands.
"Oh! Li.. sa... Oh!"
"Come on, it's not like I'd masturbate in front of you and not let you have some fun" Lisa looked up at him with a huge grin then, without so much as even pausing the handjob she was giving him, looked over at her other bodies. "Though, I do suspect watching me masturbate is fun in itself." Lisa looked back down at Eric's crotch, and gasped as he came. His cum fired up, hitting her in her face and on her breasts.
But that wasn't even what caused her to gasp. "Oh my god! Eric! You... you made yourself a match!"
Barely able to comprehend what she was saying after having gotten the best handjob of his life, Eric simply lay motionless on the sofa as the 2 Lisas in the middle of the room took her masturbation to a higher level, and inserted both of her penises into her vaginas.
"OH!" all 3 Lisa's exclaimed. The two Lisas started to buck and and forth into herselves, pumping her penises in and out.
Lisa on the couch tore Eric's shorts and underwear off, revealing his crotch in its full glory. Like Lisa, he had given himself paired genitalia - He still had his penis on his left, but on the right was a brand new vagina, moist, aroused, and wanting to be touched.
Excited by the discovery that Eric had gone out of the way to make himself specifically compatible for her new genitals made Lisa happier and hornier than ever. Or maybe that was cause 2 of her were having sex and were both about to blow their loads. Either way, she knew she wanted to have sex with Eric this instant.
Lisa grabbed at Eric with the 8 arms on her upper torso and the 8 arms on her first taur segment that she didn't even know how to control but was instinctively using, and spun him around so that his head was lying on the headrest, and his legs were below her body.
Lisa lowered herself onto him, using 2 of her arms to make sure her genitalia and his genitalia lined up, then she threw her upper torso down onto him, embracing him with a kiss as her head met his. The impact of her 8 huge breasts almost knocked the wind out of him, but it also got the response Lisa wanted - Eric was instantly hard again.
She bucked in and out, raising her entire upper torso off of his body every time, and squishing her many breasts back into him every time she came down. It wasn't long before they both came. The feeling of a dual male and female organism at the same time was not something either of them were properly prepared for. Both of them felt pure ecstasy take their minds.
But that wasn't enough. Lisa kept bucking and squishing her breasts into him, even before the feelings from the first orgasms had started to fade. Immediately, he was hard again.
They repeated this for hours, both reaching both male and female climax many times, until Lisa collapsed on top of Eric.
"I love you, hun."
"I love you too." Eric shifted a little towards the edge of the sofa so Lisa could rest her head against the headrest and looked out towards the center of the room. Standing only a couple feet away, staring at Eric and the Lisa on the sofa were the other 2 Lisas, fondling their breasts with 8 hands, and teasing their genitalia with 4 hands reaching from her first taur segmen.
The Lisa standing on the right winked and said, "What? I put on a show for you, you put on a show for me."
Eric faintly smiled, and turned back to the Lisa resting on top of him to find her eyes were shut and she had apparently fallen asleep.
Looking back the other way, one of the other Lisas was already walking away towards his bedroom. The other stepped closer and whispered. "Don't get me wrong, you were AMAZING! That was the best sex I've ever had. But I'm not exactly a singular kind of girl now, am I?"
Almost completely drained of strength, all Eric could do was shake his head.
"Exactly. Don't feel bad, I'm just going to wear out these other 2 me's. I could never replace you." She leaned in and gave him a quick kiss on the check.
"Oh, and don't wake me up." Lisa pointed at the sleeping Lisa laying over Eric on the couch, trapping him. But Eric couldn't respond - he too had fallen asleep.
Smug and incredibly happy with how her day had gone, Lisa walked over to Eric's bedroom where her other awake body was waiting sprawled out on her back on the bed.
"Alright, let's see what this feels like when I use ALL of my body" both said.
