Chapter 7: Allie

My plan worked. I'd deliberately sent Paul away with a hard-on, thinking he might take out his frustration on one of both of his sisters. I'd also introduced him to the idea of massaging them – with baby oil! I was pretty sure he didn't realise that baby oil is the kiss of death for condoms.

I left the bottle where it was clearly visible and went to clean myself up in the bathroom. I took a few minutes to rub myself into a nice little cum, during which I heard Paul and the girls go past the door into the girls' room. Paul's footsteps are heavier than either Danni's or Rachel's, and I heard him divert into my bedroom and back out again. I gave them a few minutes, then, cleaned up and wearing a cotton print summer dress, I went across the landing into my bedroom. As I'd hoped, the bottle of baby oil had gone. I imagined it being put to good use in the next room.

I heard the creak of the bed, followed by rhythmic sounds. My pussy spritzed – it seemed to do this every time somebody was fucking. I crept along the landing until I was outside the girls' room. I had unconsciously begun to rub my bump, my hand having found its way under my dress to my bare pudendum. I was juicing again, and rubbed my clit in time with the noises coming through the door. Finally, I heard Paul grunt and imagined each time that he would be spurting more of his baby-makers into his fertile sister, probably unaware that, if baby oil had come in contact with the condom, he would probably be firing live rounds directly into his sister's womb.
