Martha's day

Martha did not believe how great having a cock was. Having a pussy was great, which is why she had kept it. She had been playing with it while shoving her kid down her cock, allowing her to cum as her child squirmed inside her new and very sensitive cock.

You felt her squirm up and into your bladder, it felt very uncomfortable. You tried forcing them out, but it didn't work, why did you go to the loo before doing this? After a bit of communication to your child and trying to get them out a few more times, you gave up and decided to wait until you needed to go. For good measure, you drank a few cups of water.

You made notes of the experiment's progress so far and decided to make use of this time to complete more experiments related to your cock. You measured the change in length caused by arousal. You found that having a cock and balls had altered what you found arousing. You had been straight before the experiments but no you found you had Bi feelings; it was possible that you had always been Bi but never explored it, you would have to remove the cock and try this experiment again later. You would also have to try removing your vulva altogether and seeing if that had an effect. You wish you had considered this effect before to get unbiased data. Nevertheless, you found yourself not only getting aroused by your normal selection of pornographic images, showcasing fit men, but also images you found of large-breasted and naked women. Both selections of images caused your vulva to get moist and your cock to become firm. You were filled with ideas about letting the men take you from behind and trying out your new cock on the women; sometimes at the same time.

You stroked your cock, ignoring your pussy for now, for more accurate data. You found yourself enjoying watching porn involving both sexes. The familiar feeling of a building orgasm crept over your body and you found it irresistible to touch your pussy. Almost as soon as your left hand brushed agist your labia you felt your orgasm peak. Cum shot out your cock and femcum gushed out of your pussy, leaving you in a sticky mess.

After a shower, you felt like you needed to experiment with a real person. It was a shame your child was still shrunken their hermaphrodite nature would have been interesting to experiment with. Luckily you had a friend who might be willing. She was lesbian but had gotten tipsy at girls' night and said how she loved girls which used strap-ons. Her name was Lucy and you gave her a call. You knew it was against the rules, no one could find out, but that was what XD001 and XD002 was for. You invited Lucy over and told her to use the back entrance through the woods at the back of your house.

As you waited, you tried to go to the loo again, your child was still inside you. You tried but you were only able to get out a few drops. You will have to try it after your experiment with Lucy. She arrived and you let her in the back. She was about 5'7 with long red hair, a slender figure and c cup breasts. She wore a red shirt and blue genes. After a bit of a friendly chit-chat over a cup of tea, dosed with XD001, which you found released all of a person's inhibitions. This made her very suggestible. You suggested you take this up to the bedroom. There you joked about fooling around, explaining you had been having Bi feelings and wanted to try some things out.

"Well, you contacted the right person." Lucy said and she gave you a kiss on the lips.

"Before we start, you should know something. I have been experimenting and one of them has allowed me to grow a cock and balls, I am still a woman and have a vulva, but I know you like a strap-on. Think of this as a more realistic strap-on." You explained.

"Cool, let's see it." Lucy said and she put her hands down your trousers. She grasped your semi-hard cock with one hand and used the other to pull your top up. While pumping your cock, she removed your top and unhooked your bra, revealing your D-cup breast. "This feels so good. You say it is real. That's so cool, oo I can feel it growing, getting hard. If men had breasts and cute faces I could enjoy this more often." She said as she groped your breast and kissed your neck.

You were getting hard and wet, you reached down and removed your trousers. You striped Lucy of her clothing, you struggled a bit with her bra, not used to taking them off someone else. Laying her down on the bed you said "I am a bit clueless about how to pleasure a woman, but I know what feels good for me."

You crawl up, between lucy's legs, your hard cock and balls swaying between your legs. You lower your head and start licking her pussy. After some pointers from her, you work out a good rhythm on her clit that got her moaning.

"Oh yes, keep that up, just a little bit more, oh yes, yes, AAAAAAAAAAAAAAAAAAHHHHHhhhhhhhh!" Lucy screams as she squirts on your face. "Oh yes, Martha, you will make a good lesbian with a bit of practice." She remarked. "Now put that cock in my pussy." Normally, she would be concerned about getting pregnant but XD001 was doing its job.

You shoved your cock deep into the folds of your friend. The novel feeling was extraordinary. Better than with your hands, you could feel the moist walls of her vagina squeezing your cock. You had put your fingers in your pussy before, this felt similar but so much more intense. You began thrusting in and out of your friend. It was odd being the one doing the thrusting, but the feeling was sensational. You could also feel your breast rubbing together, your nipples and hers occasonly rubbing. Pleasure ran down your spine and into your pussy, currently not receiving much love.

"Oh that feels much better than plastic!" Lucy moaned, "Why are men so unattractive when this feels so good, I am so glad you invited me for this. Come on, fuck me, hard." She moaned.

You felt her getting wet around your cock as you thrust. You felt the pleasure building up. Soon you found yourself ready to explode. "OH YES AAAAAAAAAAAHHHHHHHHHHH." You cried as you came deep inside your friend, you also felt yourself coming from your pussy, dripping femcum down your legs. You pulled out and collapsed next to Lucy on your bed. Cumming from both organs had drained you and you were currently in the afterglow.

"I'm just going to clean up." Lucy said. She got up and waddled to the bathroom.

As you recovered and felt a great need to use the loo. In all this, you had forgotten about your child. You needed to pee, now. You rushed to the bathroom to find it locked. "In a minute" Lucy replied as you tried the handle. You were ****, you began to jostle from side to side to hold your pee. When the door finally opened, you rushed into the bathroom as Lucy went to get dressed. You stood to pee, another advantage of your new equipment. Urine started to stream from your cock.
