Let the se...um...learning commence!

We had to relocate before we could really begin. With Peridot on the floor, it was nearly impossible to penetrate her while letting Lapis ride her face at the same time. The looks they gave me weren't pleasant. "This BETTER be worth it," Peridot hissed. Her angry expression really didn't work with the shine of Lapis's fluids around her lips.

I was quick to apologize, explaining my error and how to rectify it. "We need to have you elevated, Peridot. My bed should work just fine," I explained. Thank god they were robo-sluts because I don't think any real woman would be keen to continue after such an awkward start. As it was, I could feel them glaring holes in the back of my head as I led them to my bedroom. Picking Peridot up (much to her chagrin), I placed her on the bed with her legs dangling over the side. "Lapis if you wo..."

"Yeah, I got it, dumbass..." she grumbled as she climbed onto the bed, resuming her position on Peridot's face. I muttered about her rudeness, but it was understandable. Now though...I took hold of Peridot's ankles, spreading her legs. Despite the interruptions, she was still visibly wet and ready to go. Pressing my throbbing dick to her opening, I offered one last word of warning. "Oh, I may have said this already, but...this might be a little uncomfortable at first. It WILL get better if that's the case, promise." Her response was a thumbs up. With that, I eased my way inside her.

The effect was immediate. For an instant, Peridot froze. Then her grip on Lapis's toned legs tightened and she released a long muffled moan. "Thuh...Think she likes it..." Lapis said between moans. With that reassurance, I began to thrust properly...albeit slowly at first. This time it was Lapis who stiffened. "Oh FUCK, she likes it!" she mewled, back arching and hips bucking against her friend's (who I guess was now a friend with benefits) face. "I...I...oh my stars!" Lapis nearly tumbled off from her position as her orgasm...which I guess was the first she ever had...rocked her body. In fact, I think that if Peridot wasn't clinging on tight enough that, if she were human, there would be bruises in the shape of hands on Lapis's thighs, Lapis wouldn't still be enjoying the efforts of Peri's tongue.

As a little science experiment of my own, I started to pick up speed. Peridot's pussy was tight, as expected, but in no way was it cramped as it might have been if she had actual organs and such in there. That, however, wasn't the experiment. I smirked as I saw that the faster I pounded Peri's pussy, the more Lapis bucked. Her tongue had to be moving at the speed of a hummingbird's wings judging from Lapis's face.

Speaking of experiments, I figured I should try to keep up the façade of this being one. "Okay, that...nngh...that sensation that's going thro...through you, Lapis? The one that feels MINDBLOWINGLY good? That's called an orgasm. Th...think of it as the end goal of this act," I explained. "Though I suppose...damn that feels amazing...I suppose that it doesn't have to be the end of it if both partners are up for more." I had no idea if either of them were hearing me at that point, but I had to continue. "And...speaking of orgasms...I...I'm about to...there's gonna be some fluid, so ju...!" I really should have explained ejaculation beforehand as I had no time to full explain before I emptied my load into her. Her pussy clamped down, milking my dick as Lapis fell to the side, rolling onto her back and panting. Her face uncovered, Peridot let out a moan of pure bliss as her own orgasm hit.

Coming down from my climax, I staggered slightly to the bed, sitting down. "So...uh...any questions?" I asked. "Yes," Peridot muttered. "When can we do it again?" "Uh huh," Lapis added.
