‘Good heavens, Agnes, when you suggested we nip upstairs like this, I was certain you were putting me on!’ he said, returning my tight embrace. �...To what do I owe this honour, anyway?’ I reached down brazenly and rubbed his hardness through his pants, knowing our wing of the mansion would be deserted for some time yet, and was rewarded with an adorably tentative stroke of his gentle hands on my breasts. ‘It is all really very simple, James,’ I confessed. ‘It’s been a year now that I’ve been on. My sister and her brother were laughing about something happening on tv.My dick sprang out of my boxers when she pulled it down. She held my dick lightly and began stroking it gently at first. I spread her pussy lips with my fingers and began rubbing her clit. She moaned and my sister heard it.“Um you guys do realize that looks weird right?” I have no clue what it must’ve looked like.Monica said “haha relax. It’s cold. It’s not like I’m going to fuck him!” They both laughed. I forced a laugh.. Once I was naked the girls had be posing in all kinds of positions including some with me on my knees spreading my ass cheeks apart while they clicked away with their cameras. I was told to get in the pool and again posed in many different ways usually with my dick or ass thrust up out of the water. I was told to get out of the pool and lay down on a lounge chair and start stroking my dick like I did last time. I started stroking and had to stop and few time and squeeze my dick to stop from. My cock was telling me that the George’s method may be right for this pair. As usual with George I didn’t get the chance. He said out loud for all to hear ’10 bucks says it ain’t real!’ I could tell they heard him. He was surely right! But, the closest I’d ever come to bedding a red pussy was jacking off while fantasying about the redheaded twins in high school. They ordered a couple of drinks and then the younger one got up walked over behind George and challenged ’10 Bucks says it is!’ .
