I let myself into the house and made my way to the bedroom. As I climbed the stairs I could hear them going at it. The bed was squeaking and there was...the unmistakable sound of Christine enjoying some stiff cock. I opened the bedroom door and was greeted by the two of them completely naked, Christine on her back legs spread wide open with him in between pounding away at her as hard as he could. Christine looked over to me but Nigel barely flinched - he was clearly concentrating on the job at. She obediently parted her legs, and a soft moan escaped her lips as I began to stroke her wet pussy-lips.The more turned on someone is, the easier it is to influence them. And with what I was about to suggest to my sister, I needed her to be as turned on as possible.“How do you feel about hypnosis?”“It turns me on.”“Why?”I slipped one finger between her slick folds.“I love the idea of giving up control, giving up power.”“When I hypnotize you, who do you give up power to?”“You.”I slipped another. "We've got to do something. After we came through that last narrowing, there's so little starlight that our sensors have nothing to magnify," Diana declared."Suit up and move the device into the lock, but anchor it there with the magnetics until I instruct you otherwise. Also, alter its settings from Standby to Ready Mode. Keep a remote with you and give me the backup. When you are ready, I will bring the lighting up enough for us to continue. Should we be detected..."As Diana moved out of her. I climb up over her spread her legs as wide as they would go and then tucked them up under my arms what a sight. There she is wide open and all wet and ready for anything. I pull out the dildo and stuff my face right in to her lovely pussy and start licking as fast as I can she goes crazy. I start pounding my tongue in for all its worth fucking her with it when she starts Cumming like crazy next she is trying to grab my cock but I know if she does I will not last so I keep moving around and.
