betwix and between

Tween had put up with an awful lot from his twin brother Twix.
Tween's demeanor was always mild and low keyed while Twix's was wild with oats to sew.1

Such identical twins you've never seen anywhere and almost nobody could tell Twix from Tween.2

Tween had a girl and her name was Terica and he loved her name because it rhymed with a quiet beauty called the Mona Lisa. She was a gorgeous creature and they had been in love for many years. They waited to get married until they felt they could afford it.3

Twix felt of all the girls he new, only Terica turned him on but he also knew Tween would never let her go so he hatched a scheme.
He practiced day and night and then, Tween was called away for a week and Twix moved in. He pretended he was Tween and even in bed the deception held. She'd never really done it with Tween very much in the past so Twix's plan went smooth as glass.4

For a whole week he had lots of fun then Tween came home and he got a bit upset at his brother. Well, he was pissed!5

Terica was appalled at Twix'a ruse and Tween was so mad but what could they do?6

To Terica's surprise Tween said nothing but late one night he shot Twix right between the eyes and he and Terica buried Twix really deep. This was one little secret they both would keep.7

They got married and were seen everywhere but to this day none know if he be Twix or be Tween.
