Explore "Your" body

It really hit you that you were in your sisters body once you heard her high pitched voice come out of you. You wasted no time in exploring her body, starting with her C-cup breasts which were still tingling from before you fondle and knead your breasts enjoy the warm feeling you get from your lower regions. You continue your exploration and massage your belly and slide your hands down to your pussy.

You let out a squeal as your delicate hand brushes against your clit, your sisters body is still quite sensitive from orgasming a while ago. You slowly start rubbing your pussy giving you a weird sensation in your belly. You insert a finger into your pussy, and enjoy the sensation you keep rubbing the inside and get into a steady rhythm and soon you cum spraying your juices all over your sisters bed. Strangely you don't feel completely satisfied and want more. You then notice your dick sitting on the bed and grab it. You notice that it is flaccid so you try to coax it back to full attention but fail unfortunately. It seems your dick is completely spent.

You sigh in defeat thinking about what to do next, you remember your sister had other dildos and toys for use and then an idea hits you. You remember the calculator had a merge function and decide to merge one of the dildos with your dick to enhance it. After rummaging around your sisters "Toy" box you find one of the dildos you like, its stupidly named as "Unyielding Magic Hypnotic Cock" and you laugh however its size is no joke and is literally the biggest thing in your sisters collection.

You position the dildo next to your dick on the bed and pick up the calculator. You quickly select your dick and the dildo as the merge targets and hit the confirmation button, there is a flash of light and there you see your dick merged with the dildo to produce an unreal 15-inch dick sitting erect in all its majesty.

You look at the dick and start drooling with anticipation, you position yourself above your dick and guide the tip to the entrance of your pussy. You start slow just inserting the tip, but soon you are taking that dick to its base with no problems, it does feel a bit weird when you can feel it bulge all the way in your belly but you don't really care as you are caught up in an orgasmic bliss. As you feel close to climaxing you take the entirety of the dick inside you, and you have a mind-shattering orgasm, the dick cums inside you filling you up and there is a slight bulge in your belly. You pass out with the lingering orgasm still effecting you.

You wake up some time later and realize that your dick is still inside you and pull it out. There is an audible *pop* and you almost orgasm again. You clean yourself up and look at the dick again and wonder how the hell you managed to fit that thing into your petite sisters body. Then it hits you, the name contained magic in it, does that mean the merge imparts properties from each object in the merge. Then you get a devilish idea, you remembered how you could just reattach the separated body part back to your body, but it doesn't have to be the body that the part is from does it?
