The family secret.

My adopted father was a hermaphrodite, and I got him pregnant.

My name is Ryan and when I was 12, I was adopted by a couple in their twenties. I noticed there was something different about Billy my new dad. But Lilly and Billy kept putting off my questions. They told me they would explain when I was older.
They called me to their bedroom the day after my 18th birthday explaining it was time that I knew the family secret. The reason they adopted me is they could not have children. Billy did not have any balls.
Billy took off all of his clothes. He had boobs A cup and nipples with areolas larger than most men have.
He had a fare sized cock but no balls.
I asked if he had lost them in an accident.
Billy lay on the bed and lifted his legs. Where his balls should have been was a cunt.
Lily put her arm around me and said Billy is what is known as a hermaphrodite. He can get an erection and shoot a clear liquid from his cock. But without balls he will never produce sperm.
Mind you if you ever got Billy drunk and fucked his cunt you could get him pregnant. Then Billy suggested I fuck Lilly and get her pregnant.
I left them arguing ang got out of there.
Not long after that it was Billy's birthday and Lilly got him drunk. He was waisted and I was a little drunk.
Lilly asked for my help to put him to bed. She even had me hold him up while she undressed him.
Lilly knelt down and started sucking Billy's cock then she got my cock out and started sucking it too.
Lilly then got us on the bed got on me and rode my cock until I lost my load in her. I love her big breasts the way they swung around under her as she fucked herself on my cock.
After I lost my load, I fell asleep. I woke up later with Lilly sucking my cock. Once I was hard again, she got me to get on Billy's back she guided me into Billy's cunt and got me to fuck him.
After I shot my load, she rolled Billy over he was fully erect, and I watched Lilly ride his cock.
By the time they had finished I was hard again, and Lilly had he fuck her again.

A few days later I was asleep in bed. When my mother woke me up. Both Lilly and Billy were in my room, and they were both naked.
Lilly pulled the blanket off of me she then leaned over and started to suck my cock, while Billy stood back and watched.
She climbed on top of me guided my cock to her pussy and started riding me.
Billy put some lube in his hand and was stroking his cock. Then Billy got on the bed behind Lilly she stopped moving as he put his cock in her arse. I could feel his cock with my cock as he slid into her bum. It felt weird and a little kinky feeling Billy's cock against mine as he fucked Lilly in the bum. After I shot my load Lilly stayed where she was a Billy fucked her arse. I felt his cock slide back and forth against mine.
Then I felt him cum in her. They got off of me, and Lilly started to suck my cock to get me hard again.
Billy leaned in and Lilly moved her mouth away from my cock and Billy took over sucking my cock. As soon as I was hard again Billy climbed up and I felt him guide my cock into his cunt. As he rode my cock his cock kept flopping on my belly.
This was just the start afternoons while Billy was still at work Lilly would Find me and fuck me anywhere in the house. In the bathroom in the shower, in my bedroom on the bed, in the loungeroom on the couch, armchair on the floor.
At night Billy would do the same. Whenever Billy sucked my cock, he would finger my arse.
Then on weekends we had threesomes that seemed to last ages. Both Billy and I would take turns fucking Lilly and Billy tried to fuck my arse while I was fucking Lilly. I kept squeezing my rectum keeping him out until Lilly twisted my nipple it distracted me just enough for him to get the head in my arse and he was soon butt fucking me.
Billy started putting on weight at first it looked like a beer belly. But then we noticed his breasts had gotten bigger and the areolas were also larger and darker. Then Lilly noticed a line down Billy's stomach, and we knew Billy was pregnant.
Then we noticed Lilly was going through the same changes.
We shopped around and found the right doctor who agreed that when Billy went into labor, he would induce Lilly, and the babies would be born on the same day, and we would tell people they were twins.
After the babies were born we milked Billy a lot so later his breasts looked like two deflated balloons.
