A/N: hey you all! Here is another instalment. I got no reviews on the last chapter; did you not like it or something? That made me really sad to not hear what you guys thought. I've decided to keep the steam in, so this chapter and the next couple after this will be M RATED. It won't be pure smut, just over the T rating though, so don't say I didn't warn you.

I don't own anything. PLEASE PLEASE PLEASE REVIEW! It makes my day!

Warning. This chapter is M Rated.

SpencerPOV

October 31st 2011

After I had dressed in my Spock costume and Morgan in his Batman one, we drove towards Rossi's mansion. My mind was whirring the entire journey as I twiddled with the phaser in my hands. Part of me was terrified to go all the way with Amelia; it was something unknown to me, a foreign concept and the percentage uncertainty for error on my part was skyrocketing with every negative thought that passed through my mind. But, as Morgan had reminded me, this was Amelia's first time too, she would also be nervous, and scared and that it was my job as her boyfriend to make her feel as loved and as comfortable as I possibly could. I guess I was also quite self-conscious about how I looked; I wasn't well built like Morgan, then again, she had seen me with my shirt off and she responded very positively going by the lovebite on my right pectoral. Was it meant to be this confusing? Typical Spencer Reid; can't even get the baser primal urges correct.

We arrived at Rossi's mansion, which was decorated to the nines in Halloween decorations. We stepped out, walking to the door and knocking. It was opened by Rossi, in a Dracula costume which looked very authentic.

"Hello boys, come on in, we're just waiting on Amelia and Garcia," Rossi said, taking the wine bottles the pair of them had brought with them.

We stepped inside, the house interior was just as good as the outside. A karaoke machine was set up near a jukebox and a makeshift dancefloor. The large dining room table was decked out with candies and other foods.

Everyone looked fantastic in their costumes; Hotch was a pirate, Jack was Spiderman, Henry, as I had seen earlier, was dressed up as me, which was incredibly touching, JJ was Superwoman, Will was James Bond and Prentiss was Wonder Woman. There were lots of Rossi's other guests milling around that Spencer didn't recognise.

Suddenly there was a ring of the doorbell and the click clack of heels could be heard, I turned and my jaw dropped.

There was Amelia, in knee high black boots, that teasingly short red dress with a phaser at her waist and her hair in an updo. She. Was. Breathtaking. God, I wanted her so badly.

Morgan wolf whistled, "looks like your drought is finally over G-man, she wants you bad." He said before sidling up to Garcia, clad in a catwoman costume.

Amelia walked, no strutted, up to me, a lusty look in her eyes that I'm sure was reflected in my own. She wrapped her arms around my neck, "you like amante?" she asked, quirking an eyebrow, moving closer to me and pulling me into a searing kiss.

I kissed her back with everything I had and maybe just a bit more, before pulling away, "I love, you look amazing." I whispered back against her lips.

She smiled, winking, "Good because it is all for you."

The rest of the night she continued in a similar fashion. It didn't matter where she was or what she was doing. She could be up at the karaoke machine, talking to Henry or Jack, dancing with the girls, anytime she wasn't with me she put on a show, like she was trying to seduce me. There was no need; I was already seduced.

I went to the kitchen to get myself another drink, Amelia was dancing with Garcia so she wouldn't miss me for a minute or two. I was wrong.

She followed me into the kitchen, I'm surprised I didn't hear the click clack of her shoes, and she wrapped her arms around me, kissing at my neck, "What do you say to leaving soon and having a party of our own?" she whispered as she kissed my ear.

I took a sharp intake of breath, turning to face her, "That sounds great, you've been teasing me all night."

She giggled, pressing herself closer, "Do you not like it amante? I thought half the thrill of it all for a profiler was in the chase." She said, her hands sliding up my shirt.

I held in a groan as she dragged her nails a little, she giggled again, before pulling away, "We leave in 10 minutes." She added with a wink, before leaving the room with an extra swing in her hips.

My heart was racing and I was breathing heavily; how could one woman bring about such a reaction within me? No other woman, not even Lila or Maeve stirred such baser urges within me. It was unnerving yet most wonderful all at the same time. I wasn't used to feeling such a complex pool of emotions all the time. She was right though; I did love the chase with her, because she always makes the chase so thrilling and spontaneous.

We said our goodbyes quickly, all of the adults giving us knowing looks. The party was just wrapping up anyway, as it was a Monday and most people had work or school the next day. We jumped into Amelia's car, her speeding away from the large mansion.

I now understood what everyone meant by sexual tension; there was such a charged atmosphere in this car that part of me, the less logical, primal part of me, wanted Amelia to pull the car over so I could jump her now. Luckily however, I still had most of my logic.

We reached our apartment building, walking quickly inside and into the lift. Suddenly, my hands began to shake a bit; a release of the built up nerves and tension inside of me, the fast dwindling logical part of my brain noted. That was when Amelia took my hands, kissing them very gently.

"You do want to do this don't you Spencer? I love you, I don't want you to rush into this." She said worriedly.

"Yes, yes I want this more than anything." I said, squeezing her hands and pulling her closer, "You are the only woman I've ever wanted. I'm just a bit nervous about disappointing you I guess."

"Please don't feel nervous, it's just me. I already like what I see, stop thinking with that monster brain. You could never disappoint me and I'm nervous too." She said, pulling me down for a searing kiss. "And before you ask, I'm already on the pill. And Garcia gave me some other stuff." She added, as the elevator dinged.

We stepped out, walking towards our apartment door, this was it. This was the moment we had been building up to all night. And I couldn't wait to see where the night would lead us once we stepped through the door.
