It was a totally mad idea, worthy of Sam's sternest bitchface, but honestly, they needed the cash. They weren't sure how long this hunt was going to take. There was a huge coven in town with at least 20 witches and they could not move on any of them until they had uncovered the entire coven. If they gave themselves away, the witches would scatter and it would be back to square one for them both. And that meant no obvious hunter behaviours, No fake credit cards, no hustling pool, or card games, nothing that would get them into fights. Sam was all about going legit and finding part time jobs but the fact was, they were already tapped out and just needed something to get them through til their first payday. And sure, maybe they would have to change their cover story just a little but Dean was sure they could pull it off.

"I hate this," Sam scowled as Dean pulled up outside the nondescript white building.

"I know, but you gotta sell it or they'll know we're scamming them. All you gotta do is remember the details and be a little more touchy-feely. Should be easy for you. I know how much you like to cuddle," Dean grinned.

"And how are you planning on pulling this off, Mr no-chick-flick-moments?" The bitchface made a reappearance.

Dean just grinned wider. "Come on, princess, we'll be late for our appointment."

Dean got out of the car and waited for Sam to join him, hand outstretched.

Sam barely managed to keep from rolling his eyes before interlocking his fingers with Dean's and putting on his dimpliest smile.

"Just remember," Sam gritted through tightly locked teeth. "When this goes sideways, it was definitely all your fault."

"It really is a pleasure to meet you, Mr Plant, Mr Page," the plump redhead in a lab coat and glasses greeted them as they walked in from the reception area. "Please have a seat."

Dean brought out his best grin, "Please, call me Dean, and this is Sammy."

"Sam," his brother interrupted before smiling softly and squeezing Dean's hand. "Only Dean calls me Sammy."

The redhead managed to keep it together but if she hadn't been so professional, she probably would have squealed. "You two are exactly the sort of people we are looking for in this trial. My name is Doctor Stentworth but please, feel free to call me Julia."

Dean and Sam took seats across the desk from Julia without unclasping hands. The moment they were settled Sam absentmindedly started running his thumb across Dean's knuckles.

"So, how long have you two known each other?"

Sam chuckled, "I've known him my whole life."

"Yeah," Dean chimed in. "Our parents knew each other really well and so we grew up together."

"I see," she wrote something down on her clipboard. "And how long have you officially been together? Any details about that would be appreciated."

"Well, Sammy left to go to school after he graduated from high school and he was living with someone there until she died in a fire. I picked him up and we decided to go on a roadtrip together and we've been together ever since. That was about three years ago now."

"I see, and how long was it before your relationship turned sexual?"

Sam had been sipping from the glass of water provided for him and he choked and coughed.

"Sorry," Dean spoke smoothly. "He is a little shy about talking about our sex life."

Sam fought down his reaction at hearing the words "our sex life" come out of Dean's mouth. "It's ok," he wheezed. "We'd been fooling around for a while, but we were in a car accident with my father. He died and Dean was in a coma for a while. I realized how much he meant to me and it really started to pick up then."

"Excellent, yes you two are exactly the kind of candidates we are looking for. Now if you will follow me, I will get you hooked up to measure physical response," Julia smiled and stood.

Sam's reflexively squeezed Dean's hand.

Julie noticed his nervousness. "I won't push you beyond what you are comfortable with. We don't need to record full sexual intercourse but the more data we get from your foreplay practices, the better."

Dean smiled confidently. "Of course." He gripped Sam's hand firmly when he started to tremble. He really should have read the fine print. But it was too late now, and they really did need that money.

The process was quick and painless, electrodes were placed to measure brain waves. Each was hooked up to a heart monitor and the technician took a quick blood sample, explaining that another would be taken after they finished to track changes in blood chemistry. Then he and Sam were left alone in the room, camera lights blinking from the corner.

Dean held out his hand to his brother and Sam allowed himself to be pulled close. Dean brushed Sam's hair from his forehead and brushed his lips against it. "We can still back out if you need to," he whispered.

"It's ok," Sam whispered back before tilting Dean's head up gently for a sweet, chaste kiss.

And then it was as if a switch flipped. Dean's head was spinning as Sam devoured his mouth, then moving, kissing Dean's jaw and neck, gently biting his earlobe, sucking hard over Dean's pulse point. Dean could only hold on tight and let the waves of pleasure wash over him as Sam took him apart. Finally Sam ground his hips against Dean and Dean cried out brokenly as he came in his pants. And then Sam stepped back, both of them breathing hard, barely aware of the staff returning and thanking them for the excellent data they gathered.

Later that night, Dean sat alone on the Impala's hood, wondering how to define exactly what had changed since this morning. And Sam followed, pressing up close against his brother, hard line down his thigh pressing insistently into Dean's hip. "You know," he whispered huskily as he once more laced his fingers with Dean's, we probably ought to keep up appearances."
