The Viagra Prank

It was supposed to be a stupid, silly prank...that's all. I had stolen one of Step-Dad's Viagra pills, and thought it would be hilarious to slip it into my step-brother's drink. My step-brother was being a huge grump. He had been cramming for a huge exam he had, and I thought sending him off to class with a gigantic boner would be funny. I had the perfect plan. "Do you guys mind?" he said as my step-sister and I sat down beside him. After talking for a brief moment, I convinced him that maybe having a glass of water would help him stay "hydrated" for the big exam. "Yeah, that would be nice of you. Thank you, guys," he said surprised. Oh, it was no problem at all. My step-sister, Shelby, and I went into the kitchen, and that's when I showed her the blue little pill I was going to slip into our step-brother's drink. And what if his teacher was a woman? Oh man, this was going to be good. We returned with his drink, and could barely contain our laughter as he drank the whole glass! We told him that we just wanted to watch some TV while he studied for his exam, but we wanted to see...you know, his boner. After about 20 minutes or so, my step-brother started shifting around in discomfort. He slid his hand into his pants and rearranged his package as we giggled on the couch beside him. "What are you doing?" I asked. "You're, like, messing with your pants." After he admitted to having a boner, we couldn't stop laughing. But that, in fact, is what gave us away. "Did you put something in my water?" he asked. He was furious. Fine, fine...I admitted to it, "Step-Dad's Viagra." He started ranting about how his grade was on the line, and that WE were going to fix it. "Why can't you just jerk off or something?" I asked him. He said he didn't have time, and then ranted again. Blah, blah, blah. Fine, I just wanted him to shut up. But I was ONLY going to suck it...nothing else. And poor Shelby, I sort of roped her into it, too. "Did you even know you could get that hard?" I laughed. "This would go a lot faster if I just fucked you. This is taking too long," he told us. Ugh, seriously? But...but...it was only supposed to be a prank. It was supposed to be funny.
