You glance about, looking for anything to further block your sister's vision should she round the corner. Would a blanket work? Maybe getting out of the house entirely is better? You try one last time to fix the situation. "Please, put the binoculars down!"
A voice several octaves lower than your sister responds. "Well, I still feel okay. They make my balls look huge, too." There are two heavy thuds, causing the apartment floor to shudder slightly. Your blood runs cold as you realize what has most likely happened, then the outrageously deep voice resumes. "Huh, nevermind. My balls look just as huge without 'em."
You dare not peek around the corner, just in case your 'sister' is peering in your direction. "Pl-please, can you set the binoculars down?"
"Sure thing, boss." Another couple thuds, and you hear a meaty thud on the countertop. "Gotta say, this place is fancy, but it's way too small. Give me a barn any day of the week over this."
"Alright. Uh, come over here?"
"Yup." In a few more thunderous steps, a positively massive creature flooded the hallway, towering over you. It was an anthropomorphic bull, though you're not clear on the species. Corded muscles rippled across his form, even in this relatively calm atmosphere. Unlike the cows, his hair was the same shade of brown as the rest of his body, giving him a far more animalistic visage. Parts of his body were far more shaggy, if that was the right way to put it. Oh, and he certainly was a 'he.' Two huge testicles jutted outward, too large to even hang between his legs. His flaccid penis was clearly longer than anything human, but the sheer mass of his testicles made it seem almost small. Perhaps humanoid cows didn't have as much depth?
It was then that you realized you were staring at your ex-sisters dick for a prolonged period of time and were dwelling on cow-sex. You shoot your gaze back up, craning your neck to make eye contact. Two massive horn nubs adorn his head, probably cut back to let him get through some doorways easier. "Uh, anyways, here's where I live, and..." You knew nothing of this new world. Were you now a single child? What was this creature's name? It clearly wasn't going to answer to your sister's name. Maybe you should just avoid it, you're supposed to be close after all and people don't always need to use names.
"Boss, didja get the key or not?" The bull's brow was furrowed, which read as confusion, concern, or anger to you.
You quickly check your pockets, and realize you indeed had an extra key. You pull it out, and show him. "...Yes?"
He snorts, the wind ruffling your hair as he turns away. "Then we can get back to the farm. The girls need milking, and so do I." He pauses for a moment. "Humans." he said, practically speaking to himself. He then turns his head just enough to get you in sight. "Sorry, you know how get a little blunt when I'm pent up."
You want to pat him on the shoulder, but that's too far out of reach. There was no way for you to turn this conversation informative, but you didn't want it to end in awkward silence. "I thought it was funny?"
"Thanks, boss."
You round the corner to see the bull carefully tip-toeing around the furniture to reach the door. As you looked on, you tried to get a grip on how to handle this. While you did lose your sister, at least you now knew that the binoculars were somehow linked to you. Whoever uses it seems to smoothly transform into a loyal cow for you, which means you may not have to worry about getting mind-wiped like the other victims and the secret is more or less safe as long as you don't tell people. On the other hand, it means someone else grabbing the binoculars could result in complete chaos.
However, it did raise new questions. Would it turn every woman into a bull and every man into a cow? Or was it something to do with your sister? Did she do something to change the outcome? Her, or his, new nuts seemed oversized. Did she accidentally damage it? With the way free, you dart over to the counter and grab the binoculars as your sister waits by the door.
"Boss, I don't think those binoculars work too well. Tried tweaking the zoom and nothing happened. Pretty cheap make, if you ask me."
"Yeah, but it's quickly becoming one of my more valuable assets." You try to shove it into a pocket, but it's just too big. You needed to get this thing a lanyard. As you approach the door, you realize you still have no idea where this farm is. Fortunately, you now had a guide.
