Yes, the viagra

A few minutes later I was fully aware of which drug I had ingested as my cock seemed to spring to life on its own. My brother was telling some story about work and I suddenly had to cover my crotch with a couch pillow.

Amy looked quizzically at me and I nodded. She supressed a laugh, but not very well. She clearly enjoyed my sudden discomfort at springing a boner in front of my brother.

"And then...fuck...what was I saying?" my brother suddenly asked. In the blink of an eye he seemed to go from completely sober to shit faced. "Damn...how much have I had to drink?

I sighed. At least she'd gotten that drug to the right person and I no longer had to worry about passing out on my brother's couch with a hardon. We humored him for several more minutes as he got increasingly more incoherent. Finally he just laid back and passed out.

"I am so sorry," Amy told me once we were certain he was out.

"Don't worry about it," I replied. "He is passed out, so you can still pull this off. He just needs to think he knocked you up tonight and everything is fine."

"Looks like thats not the only mistake I need to fix tonight," she said, looking at the pillow I still had over my crotch. "He is out, so we don't even have to hide tonight."

I looked at my passed out brother and felt a little guilt. But god I was fucking horny.
