Jack leaned back against him, his head resting back against Mark's shoulder.  Mark pressed his warm cheek to Jack's cold one and started to hum softly to him.  Jack sighed softly, laying his arms over Mark's as Mark's hands explored over Jack's bare chest.  Mark loved when Jack was like this.  He always had so much energy around everyone else, but whenever they were truly alone together... Jack was always so calm.  Jack was a big hugger, but an even bigger snuggler.  Jack's voice came out as a soft moan, when he told him.  "I love when you do that".  Mark kissed the nape of Jack's neck, whispering against his skin.  "When I do what"?  Jack smiled, answering breathlessly.  "When you do this and hum. It's so relaxing".  Mark brushed his lips up Jack's neck to his ear, whispering in a deep buttery voice.  "I thought you loved my deep voice"? 

Jack blushed, looking at Mark out of the corner of his eye as he smiled and answered.  "That too. It gives me goosebumps".  Jack shivered in his arms and Mark chuckled softly.  Goosebumps were forming on Jack's arms, but Mark figured that was due more to the cold air than him.  Mark playfully nibbled the point of Jack's ear, before telling him in that same deep buttery voice.  "Maybe we should go back to my car? It's warmer there. We can make the windows fog up".  Jack shook his head shyly, mumbling out.  "No. I want to stay here. I pretty sure you can keep me warm anywhere".  Mark chuckled, his fingers intertwining with Jack's.  For a few minutes, Mark just held Jack in his arms and hummed softly against his ear.  Then Jack turned his head to pressed his lips to Mark's.  Mark released one of Jack's hands to cup Jack's cheek. 

Mark's heart seemed to slow down until he couldn't feel or even hear it beat.  Every time he kissed Jack, it was like kissing him for the first time.  He felt weak in the knees, but at the same time strong enough to conquer the world for him.  Jack turned in his arms to face him.  Their kiss becoming increasingly more sexual as Jack teased Mark's tongue with his.  The way Jack's tongue slid against his made his dick grow harder.  Jack was practically fucking him already.  Jack's hands cupped Mark's jaw and he pressed his body against Mark's.  Mark was becoming breathless.  Wrapping his arms around Jack's waist to keep him close, Mark reluctantly broke their kiss to whisper breathlessly over his lips.  "I love you, Jack".  Jack blushed a deep red, closing his eyes and pressed his forehead to Mark's, whispering back.  "I love you too". 

When Jack opened his eyes, their eyes locked as Jack's hands slid down Mark's chest and stomach.  When Jack's fingers began to unbutton his jeans slowly, Mark asked him in a playful tone.  "Will you still love me in the morning"?  Jack smirked at him, answering just as playfully.  "I'll let you know in the morning".  Mark smiled, watching Jack slowly start to lay back across the floor.  Mark carefully kneeled down, before leaning over him.  Mark kissed Jack's lips tenderly for a moment.  Then reluctantly pulled away to inform him cautiously.  "Jack... I don't have anything with me. I didn't think we'd be doing this... here".  Jack licked his lips, placing a hand on the back of Mark's neck, whispering back breathlessly.  "I'll be alright. I want you just like this".  Mark's heart felt like it was bursting at Jack's words. 

Jack could make him feel so special.  Jack pulled Mark down into another kiss, his hand sliding up his neck and through his hair.  Mark pushed his own pants down his legs a bit and Jack broke their kiss to roll over.  Mark stared in awe a moment as Jack shifted onto all fours under.  He couldn't believe how lean Jack was.  Yet, he could clearly see the muscles under his pale smooth skin.  Helping Jack push his pants down his thighs, Mark gently squeezed Jack's thigh.  He knew Jack was more than strong enough to support his weight, but he couldn't help himself.  He loved feeling how strong his legs were for himself.  Jack shifted his legs a bit wider, gasping softly when Mark curled his hands around Jack's thighs to pull him back against him.  Mark stroked Jack's bare back comfortingly as he shifted more comfortably behind him. 

Jack arched his back like a cat when Mark's hand slid up his spine.  Jack still felt cold to the touch.  So, Mark laid himself over Jack's back to kiss his shoulder lovingly.  Meanwhile, Mark let his free hand slide around under Jack to fondle his hardening dick.  Jack began to moan softly and sank farther into a bow as Mark's hand warmed the rod between his legs.  Jack's moans grew louder and he began to grind his hips back against Mark.  Mark had to bite his lower lip to keep himself under control against Jack's teasing.  He didn't have any lube or protection... but he an idea for at least one of them.  When Mark's hand started to feel wet from playing with Jack, he take what he could and smear it over Jack's ass.  Precum wasn't the best lube, but it lasted longer than spit.  Jack caught on and began to help. 

Switching off from stroking himself to stroking Mark's cock.  Mark licked his lips nervously.  Eventually spitting on his hand to get his dick more damp.  He really would have preferred waiting until he had things that could make this more enjoyable... but Jack couldn't seem to wait.  He started to get impatient.  Mark cautiously pressed the head of his dick into Jack's ass and froze as Jack hissed through his teeth.  It didn't matter how many times he slept with Jack... he always felt so tight.  Especially, when he was already hard and ready to go.  Mark started to pull out, when Jack reached back to grab Mark's thigh.  His fingers digging into the muscle as he moaned out.  "Don't! I'm alright. Keep going".  Mark sighed softly, bracing himself over Jack's back as he slowly pushed himself in deeper.  Jack arched beneath him, moaning loudly as his nails started to claw against Mark's thigh. 

Mark winced a bit from the pain, but forced himself to ignore it.  If he was causing Jack pain than he could endure this.  Jack suddenly released his thigh, panting out in pleasure.  "Oh, Jesus Christ! Oh, that feels good"!  Mark wrapped an arm around Jack's waist to keep his hips pressed back into him, while he also began to milk Jack for more moans.  Mark panted softly against Jack's shoulder as his rhythm started off slow, but slowly grew more intense.  Jack's moans grew louder as he started to reach his breaking point.  Mark was hoping to get Jack off before himself, but he wasn't sure that was going to happen.  He was already struggling to hold himself back.  Biting Jack's shoulder gently, Mark tried to mumbled out a warning over Jack's moaning.  "Jack... I'm-".  Mark couldn't finish.  He had to close his eyes tightly and focus just then.  He was getting to close.  The feeling of cumming was starting to overwhelm him. 

When Jack began to claw at the floor as he panting out.  "Mark, Just do it"!  Mark started to sit back, but Jack grabbed his arm tightly to hold him in place over him.  Mark only had a very short time and he was trying to pull out before cumming.  However, since Jack grabbed his arm... Mark's body gave in to the feeling.  Bursting his warm sperm deep into Jack.  Jack was even quick to follow.  Only his sperm sprayed out across the wood beneath him.  When Mark finally pulled out, his body fell to the floor exhausted.  He hadn't cum that hard in forever.  It was like his body was trying to unload every drop into Jack on purpose.  Jack laid down in his arms, looking just as exhausted.  Mark ran a hand through Jack's hair, panting out sweetly.  "We should have sex on Halloween more often".  Jack chuckled just as breathless, snuggling back into his embrace. 

Mark stroked Jack's arm, looking over his own shoulder at the sound of a soft rustling noise.  On a tree branch outside the treehouse window was a large black cat.  Mark blinked, his eyes straining against the bright full moon that illuminated behind the cat.  The black cat's eyes looked like a shocking emerald green.  He'd seen those eyes somewhere.  The cat stared at him for a second, before stretching and scampering off farther up the tree.  Mark shook his head.  Halloween at a witches house on a full moon with a creepy black cat... No wonder the sex felt different.  He was practically spooked with the creepy atmosphere this whole night was setting.  To Be Continued...
