"Hey Orisa, what's that over there?"
Sufficiently distracted for several seconds, you took the opportunity to wander up to Eli, shimmy your pants off, and plunge your butt right down into her head.
SCHLRP!
It was child's play to cram her head inside your ass and slide it down over the rest of her small body with ease; she wasn't even struggling by the time your rump touched the cold, hard floor, leaving just her feet to poke out. With just a small grunt, you pulled those in as well, leaving your stomach slightly larger then it already was, but significantly harder. It was only when you pulled yourself up off the floor that she began to struggle, and Orisa turned around to see you trying to wiggle your pants back on.
"Excuse me, but where did Creator Eli go?"
You paused for a few seconds, shrugged, then turned around and pulled your butt cheeks apart. She took a moment to stare, blink, and then plunge both of her hands right up your ass, eliciting a soft moan out of you as she reached further inwards. You instinctively clench and pull her in some more to help, but it's like she doesn't even notice. Her arms slid inside with little resistance, and your stomach was already stretching out more by the time you reached her shoulders. She ducked her head inside and began to call out for Eli, while you simply clenched and pulled her in more. Her powerfully built shoulders and large set of equipment on her back took some effort to get around, but were soon sliding up your rump alongside her torso. It was right about then that you remembered her lower half was that of a horse, not a human, which made her considerably larger then most Omnics. A nervous gulp, followed by another clench of your sphincter had you keep on going. Metal creaked and groaned audibly as you worked your ass around the rest of Orisa's body. By the time you started to engulf her front legs, she finally began to kick and struggle, her arms forming large bulges as they pushed out, while her legs tried to find some purchase, but to no avail other than to arouse you even more as her front legs wiggled considerably up against your inner anal walls, causing you to pant and moan almost uncontrollably. With another groan of metal, her 'horse's' body was sliding in to join the rest of her inside of your stomach and you couldn't be happier about it. Using her own weight against her, you managed to sit down and force her hind legs up with a noisy squelch, sending her metal hooves in and trapping her for good.
With a panting sigh, you looked over your Orisa shaped belly and rubbed as much of it as you could reach; it would be hell to digest her, but you had managed to shove the near 1 ton peacekeeper up your ass in its entirety, and it was squirming in futility for freedom. There was no way you could move with her still in on piece, all you could do was to sit tight and wait.
