Experiments of the bent gender variety

Mark had been curious considering other options for a while but eventually the busty Goth in his lap managed to convince him that there was nothing better than taking a cock.

The first thing to do was the most basic while the gender option seemed a lot more complicated sex itself was a pretty basic toggle. And Mark could see a somewhat attractive and slightly muscular female version of himself. Some features were softer and honestly he looked a bit cuter as a girl, but the rest of the features were kind of boring flat ass flat chest. Nothing like the voluptuous bomb shell that he had just spent the better part of the afternoon enjoying

Jill appeared to have the same thing on her mind.

"Not bad kind of looks a little bit like me before you make me a hot Goth mommy with a bit more muscle,"She commented clearly not minding her transformation into a complete harlot by her older brother's hand.

Let's see if we can make this one more of a collaborative project that I like the sporty look but let's do a little bit of creative copying and pasting.

The sinful siblings pulled up Jill's profile and moments later started matching the proportion to Max. Max wasn't going to have the same dark aesthetic there was something truly alluring about having a not quite matching set especially when both of them would be incredibly perverted together. While it was fun to surprise Jill with a whole new outlook, both siblings were quite enjoying the prospect Mark was going to be a woman for a while he might as well fully embrace being a complete and utter tramp while he was at it. A perfect and gorgeous feminine form although Max made sure that both he and Jill were not going to abandon each other.

"Mark and Jill are deeply in love and will find the other attractive regardless of sex gender or current presentation" a little safety precaution to make sure that neither of them would be selling the other into slavery or something.The siblings had thought of everything at least as far as they were aware, Mark would gain all the understanding necessary to pass as a woman convincingly rather than a man in a woman's body some sexual preferences were tweaked a little bit and just add a little bit of fun to the mix both added a special clause that was going to make the rest of the week incredibly entertaining. Mark could already feel his erection at full mast at the possibility of going through the whole experience from both sides. And of course they could always...

Mark felt his body begin to tingle The first changes were in his extremities his fingers and toes began to slightly thin becoming dainty and perfectly formed he was glad he wasn't standing as he felt the centre of gravity shifts ever so slightly his legs began to change shape using a little bit of their musculature and becoming more pleasantly roundedAs they approached his buttocks which began to puff out Jill had given him a relatively trim ass as a man but now he felt it bulging outwards twisting him to move forward as his waist had narrowed the changes were moving down his arms now and he felt his pictorial muscles beginning to shift his flat chest puffing out as a pair of beachball sized teats slowly inflated from his chest he let out a grasp as the changes started to reach up into his throat is deep male voice raising an Octave or two as he felt the sheer delight and pleasure of his masculinity melting away it is face and is genitals at the same time. His jawline softened and his lips grew thick while at the same time his thick masculine erection began to spurt and spray his balls growing smaller as they slipped inside a new form orifice

Then finally came the mental changes Mark had already been partial to cock after Jill's first mental alteration but now her masculine and feminine preferences were switched. She still loved girls still loved pussyBut now Marcy had increased love of putting things inside her rather than being the inserter. She grabbed Jill by the waist and pulled her into a passionate kiss moaning with delight as she felt the last shreds of her former masculine identity fading into the background her huge breasts rubbed against Jill's her cold metal studs with perfect stimulant for Marcy's new massive mammories.

Both girls moaned fingers dancing around the rabbit hole

Marcy grinned her fingers digging deep into her sister as the younger girl returned the favour.

"I'm so glad you convince me into doing this Jill, I just can't wait to find a couple of studs, maybe we should go out clubbing tonight, unless you want to stay home and see what we can make a daddy do," she cooed suddenly painfully aware that her straitlaced and mildly boring father would probably be something incredibly hot for her incest obsessed sister.Marcy could feel her world opening up again one girl was great two girls offered so many more possibilities for debauchery and it wasn't like they were limited if she really needed to change suddenly all she needed to do was start having sex with Jill and ask her perverse little sister to give Marcy back her cock no need to change the rest of her, Or maybe give them both an addition so they could breed each other.

Jill clicked her tongue against her top teeth, a habit she seemed to have instinctively picked up ever since receiving the piercing, she was clearly torn. Going to the club would definitely result in them both getting laid potentially by multiple partners and that was something that her slutty side found irresistible, but waiting at home and seducing their father would basically allow Marcy to experience the same joy she had felt when Mark had planted his thick sticky member directly into her quivering quim. There was also the possibility of having their mother join in as well it wouldn't be hard a few little tweaks and they could either have another slut or another stud.
