We arrived back at the plane, Sandy slept as I flew us back to ‘our’ airfield where we were met by Alan. ‘Had a good time you two’ he asked an... before I could answer Sandy said ‘Yes.’ I thanked them for the afternoon and as we parted Sandy kissed me on the cheek, right there in front of her dad! See you next week she said, it seems I have a new instructor. The following day I got a phone call from Alan inviting me over to lunch on Sunday. I instantly accepted in the hope Sandy would be there.. "Sandra got on the couch and manoeuvred her large phallus over Catrina's mons then ever so slowly worked it in. Catrina groaned loudly in joy. When Sandra was all that way in she paused and kissed the woman beneath her. "This is how you are going to be treated for the rest of your days. We will make love to you every night and your new husband will plant his seed in you many times. You will bear him many more children and all of them will be loved." With that Sandra pulled out and thrust hard. Becca’s pussy flexed around my cock like it was trying to milk out my white seed. I held onto Becca’s hips as I pumped her from behind and realized that Babs had scooted in under Becca and was playing with her tits. Watching my wife enjoying the tits of our babysitter as I pumped the babysitter from behind was an incredible turn on. I held Becca in a position that allowed my cock to work on her g-spot and before long she exploded with another orgasm. Babs shifted positions again and I could. Watching my girlfriend do this to another man was so hot and such an incredible turn on. Especially as his girlfriend was only feet away from us, naked, legs spread wide and masturbating, three of her fingers buried deep between her wet, puffy pussy lips, and Carol’s hand slowly working up and down on my pulsing cock. I nearly climaxed all over Sarah.When Carol released John’s cock from her mouth and turned to me I told her how I felt and where I’d almost come. It seemed to give her an idea..
