I did. But also Lapis.

Shaking my head, I sigh. "Sorry, Peridot." I show her the result of the coin toss. Lapis pumped her fist as Peridot took the coin from me, staring at it as if it was the source of infinite sorrow and disappointment. As she did so, Lapis shrugged off her jersey and t-shirt. To my surprise, she seemed to be wearing a water bra. It retreated from her chest, flowing into the gem on her back. "Now that's handy," I remarked.

"...mine are better," Peridot mumbled, pulling her camera out. "Let's get this over with." Aww, she was moping now. Still, I had to abide by the coin toss. Besides, Lapis had finished shucking her pants off and was clearly ready to go. It would be rather harsh to just tell her I changed my mind because Peridot was pouting.

"Okay, Lapis, I'm going to need you to...hmm...either bend over the couch there or lay back on it with your legs spread," I instructed. I couldn't really go over EVERY possible position. Mostly because I don't know all of them but also because I don't have the time or the patience. My dick was ready to go. It was faster for her to just bend over the arm of the couch and give me a thumbs up.

Peridot's eyes widened and her breath quickened as I moved behind the taller Gem. "Now, the first thing that we should do is make sure she's ready," I noted. "I am!" she insisted. Shaking my head I reached between her legs and ran my finger along her dripping pussy. Letting out a gasp, Lapis gripped the couch tighter. "Okay, NOW we know she is. Alright, Lapis, this may or may not be pleasant at first but regardless, it should get much..."

Turning her head, Lapis glared at me. "Whatever you're going to do, DO IT! I'm going crazy here!" she snapped harshly. She was actually shaking with a combination of irritation and arousal. I had a feeling that if I kept delaying, I could be risking flood damage to my house. I might have been hearing things, but I could swear I heard the pipes rumbling slightly in the walls. ...I really hoped that she didn't cause damage when she climaxed.

"Right, so...simply put, this," I said, gesturing to my erection, "goes in here." And with that, I rather unceremoniously thrust into Lapis. I let out a sigh of relief. I had actually been afraid her pussy would be cold. I mean, water isn't normally warm, it has to be warmed up. As for Lapis, she went ridged at first before letting out a shuddering moan. It became a lot louder and steadier as I began to piston my cock in and out of her slick pussy, slowly at first, but gaining speed. "While...ngh...while this is normally used for the purposes of breeding," I grunted to Peridot, "the pleasure it causes also makes it suitable for recreational purposes. Particularly with those who...ngh...have an affection for one another."

Her mouth opening and eyes rolling back, Lapis Lazuli came, her pussy clamping on my member. "Oh fuuuck...!" was the most coherent thing she could muster. I clenched my teeth, trying to hold back my own climax. "As...shit...as you can see, Lapis here just had an orgasm," I noted. I don't know what Peridot was doing, I couldn't really turn to look without breaking concentration and risking blowing my load just yet. "And...I despite...my best efforts to p...prolong this, I'm going to follow suit!"

With one last thrust, I slammed my dick in as far as I could go before shooting my wad inside the robo-slut. Immediately, Lapis came again, her pussy milking my dick in a way that almost made my knees give out on me. Phew...
