"So... how does it would work?"Suzie asked.
"Well it will be started by...Let's me pull down the zipper first."Luke controls both of their arms to pulling down the zipper and see what happened under the suit,their bodies actually combined as one!
"Wow, it just like our parents!"Suzie surprised and tickle couples conjoined stomach.
"Suzie please, it really tickle."says Sarah.
"Okay,but what next?"
"I think the collarband can hold us if we try hard,maybe?"Luke said.
"Let's me try."
Suzie get closer to the couple and push her head through the collarband which Luke's head stays,it seems fine. But problem comes when they pulling up the zipper.When they pulling up the zipper,Suzie's body getting closer to Luke and Sarah's body and her head getting closer to Luke's head too,they pulling further,the harder they pulling the zipper,even Suzie's arms comes through the suit to help pulling the zipper.When the zipper comes to the end,Luke feeling his head is extremely close to his sister's head.
With a 'ting' sound,the zipper comes to the end.
"That's pretty hard than I think."says Sarah.
"Indeed.Wait why I feeling funny?"Luke noticed his mouth has something else and has two perspectives through his eyes.When he want to figure out,his mouth spoken its own and has a familiar voice:"What wrong brother?I think we wait what?"
Luke shocked and feeling strange,he turned around to Sarah and Sarah truned to him,want to know what happened to her boyfriend and shocked what she saw:On her boyfriend's head,there two tongues in his mouth,four eyes and ears on his head,and his hair get longer and very like to his sister.
"Luke you looks very strange!"
"I know but I wait did we make it or not?Where's Luke?"Luke saying but with Suzie's voice in the middle.
"Wait wait wait,I think your heads merged together after we pulling the zipper."
"I guess so."says Luke with two voices."So we got some glitch?"also Luke but only Susie's voice.
" I think...yes and it not the only thing that we get some glitch."Sarah looks around their body.
Their body becomes not simply conjoined twins or triplets,but with all of their arms and legs:Luke's arms at the upper,Sarah's middle and Suzie's bottom.Luke's legs at the inside and Sarah's legs at the middle and Suzie's legs at the outside.And they also has four breasts which upper is Sarah and bottom is Suzie.
So they are a twohead which one of them is merged from two people,has six arms and legs, and four breasts.
"That's...really unexpected."says Luke and Suzie's merged head with Luke's voice."But I really like it though,I getting closer than ever before with you brother,even more than your girlfriend."Their mouth smiled and laughed with two tongues.
"So what we gonna to do next?"says Sarah.
