I had to tell Laura what my father had done to me. I think she might have worked it out anyway from reading his notes while I slept but if she was going to get revenge, she needed to know where to start. It took a while for me to get the words out but after I told her everything, she was there to comfort me and to reassure me. Then she told me her plan.
Laura had read my fathers entire notebook and not once did she see any reference to what the drug did to men, but it did reference that the drug was formulated for couples so we felt pretty secure in the knowledge it would do something to men. If we could dose my father and then the boys, we could make them feel exactly what they had put us through. I tried to argue that we should just go to the police but Laura didn't think they'd believe us and the thought of a more direct form of justice appealed to us both. My father had ruined my life, it seemed only fair that I should get to ruin his.
In the morning we walked to mine and saw that my fathers car was still missing. Exactly what we wanted. We walked into the house and went straight to the fridge. My father was a man who was proud of his health, he worked out every day and drank only bottled spring water. He hated the chemicals they put in tap water. We went to the fridge and dosed every single one of his water bottles in the fridge. We had no way of knowing which bottle he would pick so it made sense to cover our bases. We then went up to my room and hid in my wardrobe. Several hours passed before we heard the front door open. I heard my father call out to see if I was home and then like clockwork make his way to the fridge. It was hard to hear where he went from there but we knew he hadn't come upstairs. A few minutes passed and then we heard the sound of grunting from the front room which seemed to slowly be gaining in volume. We had him. Now time to reveal ourselves.
Part of Laura's plan was to not only dose my father but to torment him as well, which meant that before he had got home we had got changed. We were both dressed in our school uniforms, but our uniforms from a couple years prior. Our shirts were too tight, Lauras was held shut by only two buttons and our skirts barely covered our bums. We were both wearing thigh high socks with our hair tied back into innocent looking ponytails. I had felt uncomfortable about the idea of dressing this way in front of my father but knowing how much it would kill him to have salvation within reach but not be able to achieve it made me swallow my misgivings. When we walked into the front room my father was sweaty and naked and tugging away at his big cock. Revulsion ran through me as I remembered how incredible that cock had felt as it split my pussy open. He looked up at us and his eyes looked glazed. It was like he was possessed. Laura looked down at him and laughed.
'Hello sir, you look like you could use a hand.' she laughed as she stood over his helpless body. He couldn't stop tugging away at himself.
'Please, girls, help me.' my father responded in a strangled voice
'What do you think Emily, should we help him?'
'That's a very good question Laura. What would even help him?'
'Well when it was us it had to be a creampie. Surely it would be the same for him?'
My fathers eyes began to fill with fear.
'Yes, that makes sense to me.'
'Well let's see if we can ring one of our good friends to come and help your poor father.'
'That's a great idea.'
I didn't want to see anyone fucking my dad. Man or woman. But I did want to know that he had been truly humbled. Looking at his naked form on the floor struggling to even make words was causing flashbacks of his body against mine. The horrendous sound of his skin slapping against mine. The twitch of his cock as he filled me with his seed. I needed to see him humiliated as I had been. We made a big show of turning around as Laura pulled her phone out of her bra. We wanted him to feel ignored and powerless. But then there was a small prick in my bum. We both snapped round and saw my father kneeling behind us, a syringe in each hand with the needles sticking out of our ass cheeks. We looked at each other with horror before jumping back and out of his reach, the syringes falling to the floor. They were both empty.
'What did you do!' I shouted at him. Watching in horror as he stood up. Every ounce of desperation had disappeared from my father and once again he stood before me, powerful and confident.
