She's naked

Dawn realized she was naked and lying on Spike's bed. Spike was sitting to her right stroking his massive cock. "Are you rested up, luv?" Spike said as he kissed her.
"Spike that was incredible." Dawn said in almost a whisper.

"Well you better be ready for more. I have a lot I want to do with you." Spike had a menacing smirk on his face. Dawn thought it was sexy and she started to feel a heat in her pussy again.

"Spike you can do whatever you want with me."

"Be careful of what you wish for." Spike's mind was reeling. It had been a good fifty years since he had a virgin and to have one now who was willing to do whatever he wanted made Spike feel like he hit the jackpot. "Nibblet let's start off with something basic. Have you ever sucked a dick before?"

"Xander's a little but I had help from Anya. But I would love to taste you." As Dawn said this she put her hand on Spike's dick and started to stroke it. She then started to lick the head and down his long shaft. She licked his balls and sucked on them, which made Spike moan. She licked back up to the head and she took him into her mouth. her left hand began to caress his balls. Spike put his hand on her head and pushed her down. Dawn was shocked she could take all of him in since he was quite larger than Xander. Spike was grinding his hips against her. She was going up and down his shaft fast. "Oh God...That's it...oh...fuck..your...wonderful...FUCK" Spike came hard. Dawn couldn't believe all the cum he was shooting out. Dawn caught most of it but some dribbled out of her mouth. She swallowed. Spike would have never guessed that Dawn could be just as sexy as her sister. Dawn wiped the cum she didn't get on to her finger and then sucked on it while looking at Spike seductively. Spike then got an idea. "I'll be right back." Spike got up from the bed and left the room for just a minute and he came back with someting that could be fun or dangerous.
"Dawnie..." Spike held out a pair of handcuffs "...do you trust me?”
