I continued pondering, and decided to at least wear my breasts. As I predicted, wearing them did not cause me to black out, though I did feel a little pain as they sealed themselves onto me permanently.
Upon finishing joining with my body, my new G cup breasts felt soft yet heavy, almost like having huge bags of water glued to my chest. I wondered to myself whether Emily had naturally had these breasts or had had them put in at Gen-Tech.
With the exploration of my new appendages, my still existing cock sprang to full length, and I gasped as it began throbbing on its own. The combination of testosterone, estrogen, and the sensational feelings of my body had put it into overdrive. I lay back on my bed at once and began stroking it. I imagined sucking it and giggled to myself as I realized how quickly I had tossed away my heterosexual feelings.
The image of the cock in my face sent me over the edge. I moaned as I sent a blast of hot cum through the air, hitting both my face and breasts. Another shot became draped over my left nipple to my abdomen. I expected it to stop as usual, but the shots kept on coming. My balls and cock felt pained as they were sucked dry by my orgasm, and before I new it I was swimming in a small pool of my own semen. I held my balls in agony as my cock continued to attempt to cum without anything left to shoot.
Somehow I seemed to cum for as long as a girl, even if I still had a cock. It then occurred to me - if I somehow preserved a sample of my semen, I could preserve Emily's memory by having our baby! The transformation has effectively turned me into Emily; genes, brain, and all; so having a baby with semen from a cock that still had my previous body's genes would not cause mutations. With this thought, I quickly grabbed a tube from the freezer and scooped up as much semen as I could, before storing it in a cryo-freezer.
Exhausted from my masturbation, I grabbed Emily's vagina replica, placed it on me, and collapsed into sleep just as I activated it.
