I was never able to put my finger on it precisely other than we simply shared a special connection. It was felt more than it was ever talked about bet...een us. We never really did talk about it over the years, we didn't have to we just "felt it". You would think after Lilly and I did it we would be or had been fucking like rabbits but we didn't, with each other anyway. We went on with life and relationships like most siblings do. What Lilly and I did produce was a sort of "calm" between us or. My pucker tried in vain to grab her fingers, the sensation so dirty and exhilarating, but it quickly gave up its battle. And then I felt the fingers withdraw once more and the cool rubber pressed against my backdoor, smooth and huge. “Here it comes!” Clare announced. Robert’s hands cupped my cheeks and held my head straight, his eyes just inches from mine and looking into the depth of my mind, while his wife’s artificial cock pushed inside me. I moaned. I gasped. My breath hitched and choked.. Thinking it nothing more than flirting, I returned to my book. The day rolled by, and just before night shift took over Daisy came in to do my obs again. As I said she had a huge rack, and I noticed this time that her top button was undone on her tunic. To be honest I only noticed because as she shut the door behind her Daisy dropped something, an over emphasised “whoops” to catch my attention. Picking up on her not so subtle hint, I shamelessly stared at her cleavage as she stood. I desire was telling me to say it but my fears were saying just don't say a word. then he slid his underwear down some and I could see the base of his cock and it look as big as my wrist. I could take my eyes of the hole as I knelt in front of it. then he knelt down and looked me in the face and said I know you want this big cock so tell me where I can hear you and I will give it to you. when he stood up, now I could see there was someone else in the booth with him. This guy was already.
