Mark in the buffer Jeff body walked over to the door to leave - he smiled at the girl and pinged the elastic on Jeff the speedo..
Suddenly Mark/Jeff buckled, and bent in two grasping his 6 pack. He let out a low groan.. With his heavy shoulders pulled forward his new lats spread revealing a quite unbelieveable broad back tapering down to the tight butt encased in the red "Jeff" speedo.
a couple of seconds passed, and Jeff/Mark straightened up. He began to examine his body, feeling it all over - he had to lean forward to look over his huge pecs to see his package nested in the red speedos - he turned to the girl and smiled.
"This new version of me is hot!!" Jeff/Mark said. She suddenly realised that somehow that the "Jeff speedos" were now in control of the body.
"Oh Jeff - I thought I'd lost you", she said "you look so hot, take me now!". Jeff/Mark suddenly realise there is a problem "If I take off the speedo's then Mark will take control of this body again". She thinks for a moment, and makes some changes on the Chronivac .. "Change the speedo's to a skin tight jock that fits Jeff's/Mark's cock and butt like a glove - oh and make it so you can't tell he wearing it", and she presses enter..
Jeff felt his speedo-self begin to change he became slick, and tighter on his hosts body, creaping further up the buff bodys crack, while the front encased his Marks dick and balls changing from red to tanned bronze just like a 2nd skin. Without the speedo's support the sheathed dick flopped between his legs - for good measure the new "skin-jock" added a further 2 inches to the buff bodies original dick size. Finally a mass of dark pubes grew from the skin-jock and the changes were complete.
Jeff/Mark stood in front of her, with the speedo's completely transformed - there was no way you could tell he was wearing the "skin-jock" the dick (apart from the extra size), balls and pubes matched perfectly. You couldn't see the edge of the jock, but Jeff/Mark scratched at the edge, and "twanged" the top of the jock just to prove to himself that he was still there.
She could hardly believe what she had witnessed, Jeff/Mark was becoming stiff, she was glad to see it all "worked" she walked over and gently touched the tip of his dick.. Jeff/Mark spasamed and smiled.. "Lets find somewhere where we won't get disturbed" she says.
Jeff/Mark finds and opens the gym bag that Mark had brought with him when he was still a girl. He pulls out Marks damp a pair of baggy shorts, thankfully they are just long enough to hide his dick. Next a polo shirt - Mark originally only weared medium size, Jeff/Mark sighed, and pulled the shirt over his new XL sized body - it was tight, and molded to his body like a 2nd skin.
They both walked out and decided to get a cool drink before getting it on.. besides Jeff/Mark wanted to show off his new body to everyone!
