Within seconds, he turned to lock the door and went right back to the laptop and dove into the whole collection of her nudes. He was barely on the second picture when he dropped his bathing suit and had his dick in his hand jerking off to his step sister.
He was hard as a rock, so needless to say this was clearly something he had thought about often. I also could not believe how thick his cock was. I could tell from the outline in his bathing suit that day that it was big, but this thing was truly a monster cock. Fat mushroom head, probably a true nine inches and thick as a coke can.
I’m not sure if he was just so turned on or trying to hurry up but he came after about 2 minutes of checking her out. Then he did the best part, he took pictures on his phone of the images so he could save them for later obviously. My mind was on fire, I now knew both of them wanted each other, badly.
At this point I was desperate to push these limits but was clueless on how. Fantasy is one thing, but no part of me thought they would act on it under any circumstances without a push of some sort. How could I let her know what happened without her knowing what I had done? I needed to “bust” him in the eyes of my wife without raising suspicion I was behind any of it.
So the first thing I did was take a pair of her lace thong panties and a bathing suit bottom I knew she’d want later that week for the hot tub and planted them in his room at the vacation house. So when she started looking for her bathing suit, I was happy to help her look around. As I searched the shared bathroom, I “spotted” them under his bed. When we went in to retrieve them, we also saw the thong pushed a little farther under the bed.
This accomplished two important things. One, it showed her that he had been sneaking around with her things and that he wanted her equally as bad as she wanted him. The other thing it did was allow me to question how they got there.
“Did he take these or were you in here and left them?”. We both obviously knew the answer but it allowed me to have that conversation.
Once she was comfortable that she had convinced me that he had taken them rather than her sneaking into his room, I was able to start asking other questions.
“Do you think he took these then?” I inquired.
“He must have, how else would they be under the bed.” she muttered.
“Why would he do that, do you think he is jerking off to you?” I asked.
“Of course not!” she exclaimed. “I’m his step-sister!”
“That is the only explanation if you’re being honest with me, right?”
“I guess…” she said, staring off into space.
I could tell she was floored but also flustered and excited about the idea of him jerking to her panties. A normal reaction would be pure disgust IF the woman isn’t flattered by it. She was just blushing and not as angry as most would act if they were truly offended.
That night as we laid in bed I began to grind on her ass as we spooned. Needless to say she was extra in the mood after the day’s realization.
As I reached around to rub her clit I asked “be honest, it turns you on some to know other guys jerk off to you?”
