"So, get this... the few reliable accounts of succubus survivors all say that the thing took the form that aroused them most, then started turning them on. This one guy, he said he was on a business trip last year, when Carmelita knocked on his motelroom door, all dressed in black leather..." Dean smirked, glad his back was still on the others. "Yeah, 'Carmelita' has retired way back when... I know, Dean." Sam sighed. "Don't remind me that you got to rock her world just once more... damn dragons." Crap. Apparently, Sammy could read his stance and breathing now. "Dragons? That was with the Mother of Monsters, right?" Cas sounded guarded. He still hated being reminded of that time. Dean closed his eyes. He could just picture the slightly closed off look his friend would have now. To him it didn't matter that Sam and Dean had forgiven the transgression. He himself hadn't. "Yeah, that was just before the dragons rose her from Purgatory. Anyway, according to the guy, Carmelita walked right up to him and started whispering all kinds of lewd things in his ear. If his wife hadn't called, he would have been a goner. The guilt trip scared the thing off." Sam continued.
"See, Dean. This is exactly why we cannot take you along. You don't have such a back-up. No guilt trips. If Sam or I respond too late, we could lose you." Cas said, still trying to get Dean to be reasonable. Dean pursed his lips. Guilt trips enough, just none libido related. "Yeah, I know." he conceded. "As soon as I get my rocks off, I'm dead." He glared at them, over his shoulder. "I do have some stamina, you know." Sam sighed. "We know, Dean. We just don't want to take the risk." he pleaded, his hazel eyes in puppy mode. Dean glanced at Cas, who had his cerulean eyes full on begging too. "Please, Dean. We need you." Dean heaved a big sigh. "Yeah, yeah, I know. Go already, and don't forget to get the monk's pepper." Sam frowned. "The what now?" Dean grinned. "HAH! One-upped you, Sammy! I did my research on those bitches ages ago." This caused Sam to raise his eyebrows up to his bangs and Cas to curiously tilt his head. "You have? Why didn't you say so?"
Dean huffed. "Because you and Captain Conclusion here never let me in on the conversation, once you figured out what we're dealing with." He sat up and swung his legs over the edge of the bed. "Alrighty then. I'll tell you what I have learned all those years back...The bitches try to get you to blow your load, and then drain you. And when I say drain, well, you saw the mummies..." Sam nodded and sat down on a chair, his eyes serious, and eager to learn. Cas was frowning. "When did you research this, Dean?" Dean smirked. "Almost as soon as I lost my virginity. I found out that my libido was, let's say, not the smallest thing, so I wondered if it could get me in trouble. Well, supernatural trouble. So I hit the books when Dad dropped us off at Bobby's shortly after." Sam gaped, and Cas just blinked. "Anyway, I found that the bitches are tough to get rid off. One guy I read of was taking monk's pepper to calm his stomach. The succubus tried to kiss him, and then recoiled at the smell of the herb. So, I researched monk's pepper, and found that in the middle ages monks used it to lower libido, hence the name." Sam frowned. "Middle ages? Crap. That means it might not be available here..." He glanced at his big brother. "Do you happen to know the Latin name?" Dean smirked. "Heh. I memorised that, what do you think? It's Vitex agnus castus." He grinned at their reactions. Sam looked impressed, the corners of his mouth pulled down into his 'Well-whaddayaknow' sturgeon face. Cas had widened his eyes comically.
