I woke up in the darkness. There was a strange rumbling and the smell of antiseptic. I tried to sit up but my wrists were shackled down. As I looked down my body, noticing I had been stripped of my clothing, I saw my ankles were also tied down. I was surrounded by machinery and technology I'd never seen before. The last thing I remember was walking out back with Bobby to feed the horses. Halfway to the barn there had been a bright flash of green light and...well, here we are. I strained to look for Bobby. Where had they taken him?
I heard a moan come from my right and looked over to see Bobby stretched out in the same position I was. "Bobby?" He stirred a bit. "Bobby?" He finally turned to look at me, his eyes glassy and unfocused. Well obviously they had drugged us somehow. I was beginning to believe more and more from our circumstances that we'd been abducted by aliens. I know it seems ridiculous, no one believes they exist. But how else do you explain this situation?
"Sis? Is that you? What the hell happened," his voice was slurred but getting stronger with every word. I blushed looking down his body to see his cock laying against his leg. But I couldn't tear my eyes away. He was my little brother for Godsake! My nipples hardened against my will. I'd never seen a dick so large. Who knew my little brother was so well endowed? I felt his eyes on me and knew he was looking at my tits. His cock began to stir as he eyed them. I smiled to myself, loving that he was getting turned on just from looking at my assets. No! This was wrong! We may be countryfolk but we're not that deep in the country!
"I...I...I think we've been abducted," I said, tearing my eyes away from his thickening cock. Just as the words left my mouth, the air-tight doors sprung open to reveal a glowing shape. As it moved towards us, the shape morphed into some semblance of a human male. It still held its glowing blue aura but had all the features of a human man, save for one. But as it looked over Bobby, what I assumed was a cock began to grow between its legs. My jaw dropped as I watched what I could only call an alien try to replicate Bobby's cock.
It turned its vacant eyes to me and slowly ran a glowing hand up my thigh. I cringed and tried to move away but the restraints kept me still. "Who are you," I screamed. It tilted its head to one side, as if it was trying to decipher what I'd said. After a few moments it removed its hand from my leg and walked over to Bobby and began fondling his balls. Bobby's cock twitched and thickened a bit but his face said he certainly wasn't enjoying the alien's touch. Its hand moved up to stroke his cock, making Bobby throw back his head and moan. I felt a pooling between my legs. I was getting wet just watching the alien pleasure Bobby.
As if sensing my arousal, the alien turned quickly to me. Its cock had thickened just like Bobby's and there was a pearl drop sitting precariously at the tip. I licked my lips, both scared of what it was going to do and excited to see what would happen next. It pushed a button next to my head and my legs spread a bit. The alien ran a single finger up my thigh and stroked my pussy lips. I let out a gasp at its warm touch. One of its fingers dipped into my cunt and I moaned. It pulled away its hand, rubbing its fingers together as if testing my wetness. It walked over to a table nearby and grabbed a circular metal ring that had tons of lights and buttons on it. The alien flipped a switch, making the lights glow and pulse. It made its way over to Bobby and slipped the ring over his still hard cock. As it did so, Bobby's cock disappeared. The alien looked back over to the table and there, standing up tall like some lifelike dildo, was Bobby's cock. His face went white. Wouldn't yours if you suddenly saw one of your body parts clear across the room?
