Castiel slumped down on the sofa, breathing deeply.

'That was relatively difficult.' he remarked making Dean chuckle. They had spent the past few weeks tracking a nest of vampires, and had finally managed to kill them all, and it had been much more than difficult. As per usual following a hunt, Dean stode over to the fridge and swung open the door, letting the cool blast of air rush over his warm body.

Peering inside, he spotted the bowl of strawberries. Technically, it was only just spring, and strawberries weren't in season, but he knew where to go, and anyway, they were pretty much his favourite thing. He washed them, put them on a plate and went back to the sofa, setting the bowl down on the coffee table. Sitting next to Cas, who was sprawled on the sofa, which was very unlike him, he picked one up and tossed it into his open mouth. Castiel watched in fascination.

Dean noticed him looking and raised an eyebrow.

'You want one?' he asked offering the bowl. Castiel took one tentatively and after turning it round in his slender fingers a few times he popped the whole thing in his mouth. Dean burst out laughing as Castiel chewed curiously.

'You idjit.' gasped Dean. 'You're not supposed to eat the stalk.' Castiel turned his disgruntled face to him, before reaching a delicate finger into his mouth and plucking the green stalk out. He swallowed the strawberry and licked his lips, trying to memorise the taste. He had never eaten strawberries before, and found them nice, if not a bit sweet.

He reached for another one, when he noticed a slight tickle in the back of his throat, followed by his tongue, until his whole mouth was tingling. He ran his tongue around his mouth wondering what was happening.

'Dean,' he said. 'My whole mouth is..itchy? Is this normal?' he asked questioningly. A fleeting look of confusion passed over his face, before he realised.

'Oh.' He said, slightly shocked. 'I think you're allergic to it.' he said. He wasn't sure if angels could be allergic to anything, but apparently they could.

'How do you know?' asked Castiel, looking slightly worried. Dean gave him a reassuring smile.

'Don't worry. Sam used to be allergic to them, the same thing happened to him. It's not very bad, and it goes away after a while.' This answer seemed to satisfy Castiel, although he kept running his tongue around his mouth. Dean stood up.

'I'll get you some water.' he announced, and made his way to the kitchen. He filled a glass with cold water and returned to the sofa.

He gasped when he saw Castiel. His lips were bright red and swollen, and his was biting and licking them to try and ease the tickling feeling. Dean tried to ignore the the stirring in his groin as he sat down and handed the water to Cas. As Castiel drank the water Dean couldn't help his thoughts going haywire.

Fuck, he thought. God his lips look good. Jesus, does he even know what he's doing to me? Oh my god, why am I thinking this, why the hell am I feeling like this? Oh shit, I have to stop staring, but god he looks hot, he won't know will he? No, he thinks I'm just worried and- fucking hell he's licking the bloody glass.

His thoughts were cut off when he noticed Castiel looking at strangely.

'What?' he asked, trying to appear nonchalant. Castiel looked him straight in the eye, tilting his head to the side.

'You just groaned. You were watching me and you groaned.' He said matter of factly, although Dean thought he could detect an undertone of slight, what was it, fear, confusion?

Deans heart raced. This was bad. This was very bad. He had groaned out loud while watching his friends lips. He inwardly cursed himself, and cleared his throat awkwardly. Castiel, appearing oblivious to what he had done, picked up the glass again, wrapping his crimson lips firmly around the rim.

Dean couldn't help his next actions. Reaching out, he grabbed the glass, snatching it from his hands and putting it haphazardly on the table, before placing his hands either sides of the angels body and kneeling between his outstretched legs. Castiels eyes widened in shock as he looked at Dean, unsure of what to do, having never been in this situation before. Their faces were inches apart and Dean could smell the sweetness of strawberries on his warm breath, and he could count every eyelash framing those beautiful cerulean blue eyes.

Keeping their eyes locked, he leant forward slowly, giving Castiel a chance to back away, but the angel stayed frozen where he was, his heart thudding in his chest. Time seemed to stretch on forever as they gazed at each other, neither daring to close the gap.

Finally, Dean couldn't bear it any longer, and he pressed his cold lips against Castiels hot ones. He felt the angel tense up, but after a few seconds he relaxed. Dean moves his lips slowly, causing a shudder to run down Castiels spine. He had never felt anything like this before, and the feeling of being so close to someone was amazing, electrifying. His eyes closed dreamily as his mind went blank, devoid of everything except the feeling of Dean so close to him.

He uncertainly moved his hands up onto Deans back running them up and down, wanting to feel Dean, to map out every inch of his body with his bare hands.

Dean moved closer, lacing his fingers in Castiels dark hair pulling them closer and deepening the kiss, tasting the strawberries on his lips.

'Hey guys, I'm- woah'. Sam stopped dead in the doorway, staring at his brother and his friend who had pulled apart just in time, but were still too close to make it seem normal. They both blushed and Sam felt his face burning with embarrassment. Sam stared at Dean, his mouth opening in an 'o' of shock, but far back in his mind, he realised he had been waiting for this moment to happen for a long time.

'I'm, err, going to put these, um, groceries away.' he muttered and left the room hastily. Dean and Castiel finally pulled away from each other, the awkward tenseness hanging in the air. Deans trousers were still uncomfortably tight, and with a glance at Castiel he saw that his were too. This gave him an almost smug feeling, but that left him quickly as the reality of what had just happened dawned on them both. His cheeks as red as his brothers he stood up and left without another word.

Castiel stayed where he was, feeling hot and flustered. These feelings, these human feelings, were all completely new to him. Yes, he knew what they were as his vessel had felt them before, but he himself, Castiel the angel, had never felt them first hand.

The arousal he had felt when Dean moved closer to him had scared him. He had never meant to develop feelings like this to anyone, it was too dangerous to become so emotionally attached to someone. But he couldn't help the love he felt towards Dean. He certainly wasn't in love with him...but maybe. He banished the thoughts, stood up and stretched, and went back to his room in the motel they were staying in, to think.

Dean returned from his walk much later then he had expected. He had spent a lot of time thinking and mulling over the incident that happened earlier, and finally decided that it would be best if they both just forgot it had happened. He knew Castiel would be more comfortable with that anyway even if deep down, it made his insides squirm with regret.

For a few months now he had felt something towards the angel. His dark, mussed up hair, his huge blue puppy dog eyes and his deep gravely voice, drew Dean in like a moth to a lamp. He was intrigued by the angel and felt safe in his presence, but he had always sensed something more, although he hadn't known it was this.

He certainly knew he didn't want to forget it. He had felt something different when he kissed Cas, different to all the other girls he had kissed. He couldn't, or rather didn't want to, place a finger on that feeling, because he knew if he admitted it to himself, there would be no going back.
