Day 30: Friday

On Friday, we invite Kristen over for some friendly competition. But that comes later, we start with some warm up first. And since Kristen is our guest, we start with her.

Once we’re all upstairs and naked, I grab some rope and tightly tie Kristen’s tits off at the base. This makes her already large breasts even larger, and gives them a nice blue-purple colouring. The whipping makes the colour even darker!

Well yes, of course I’m whipping them. What would you have done? I whip them nice and proper, left to right and right to left. Since I’m a righty, left to right is a bit harder for me, but I soldier through. Can’t have it said that I don’t give my all for my guests, now can I?

So, there are some nice stripes on the purple background when I’m done. And to put sort of a cherry on top, I clamp her nipples with Anna’s lovely clover clamps.

Considering the leakage between her legs, Kristen seems to be satisfied with our session so far.

Before our guest arrived, my stepsister and I prepared some clothes pins: we tied them to some strings and made them into zippers. So now you can clamp a whole bunch of clothes pegs onto a person, and since they are all tied together, you can rip them off all at once. Ripping of one clothes pin is painful. Ripping of dozens of them at the same time ... that’s next-level painful. At least according to Anna, who of course is our resident pain expert.

We prepared four of these zippers, and now I’m clamping the first one on Kristen’s tits. There are about 15 clamps on each zipper, and her luscious breasts provide ample opportunity to fasten them. Her nipples are already occupied by the clover clamps, but I put several clothes pegs onto her aureola.

The second zipper ends up on Anna’s tits. They are much smaller than Kristen’s, but I put the clamps close together and I manage to fasten all of them to her flesh. The first and the last clamp go onto her left and her right nipple, respectively, which so far had been left free.

The third zipper goes between my step-sisters legs, forming a line of clamps on both of her pussy lips. The very last clamp goes directly on top of her clit.

Finally, I put the last zipper on Kristen’s pussy lips, also finishing on her clitoris.

Now, I must admit that I might have miscalculated this next part a bit. Just a bit, you understand, but still. The plan was to torture and tease both of them, but if they wanted to cum, they had to rip off the zippers from the other, causing their friend a lot of pain.

What actually happens, once I explain the rules to them, is that the two teens share a brief look, and then grab each others zippers and brutally rip them off!

Well, at least it really must be very painful, judging by their screams.

There are a few protests that they are both owed an orgasm, but I declare them to have cheated, and cheaters don’t get orgasms. It’s the rules.

Moving on. We are having a little competition now. I have both girls lie down on their backs, side by side, legs spread wide. Now I am going to whip them on their cunts, and whoever closes her legs first, so that her knees are touching, looses. Easy, right?
