“You are acting like I cheated on you or something!” I say throwing my bag on the couch.

Andy forgetting my birthday decided to show up at the part just as me and Chris was seeing a duet of Angel eyes.
Andy of course jumping to the conclusion that I was cheating on him.
“And this whole silent treatment is really childish.” I say turning around to face Andy.
I didn’t get to finish my rant because I was cut off by Andy moving forward quickly. Taking my face in between his hands his slams his lips to mine trapping my words.
I kiss back roughly putting my anger into it, it mixing with his. Pushing me back he presses me roughly up against the wall, pinning me there.
I wrap my arms around his neck tangling my fingers in his raven hair, as he kisses down my neck.
I gasp loudly when he finds my sweet spot, him sucking and biting hard enough I know it will leave a mark.
When he lifts his head his eyes rake over me, there blue color a few shades darker. I watch him smirk when his eyes land on the mark he just left, making me realize that was his point.
“That-” I start but get cut off by him placing his finger to my lips.
Shaking his head the smirk on his lips growing. He moves his hand slowly down my face to softly grab my chin with his thumb and first finger.
Tilting my head back he bends down softly kissing where he just left his mark. Moving just a few inches lower leaving kisses in his wake he leaves another mark just over my collar bone. I shiver as his hand runs up shirt his fingertips cool on my heated skin.
I close my eyes and lean my head back on the wall as his fingers ghost across my back, his mouth still leaving marks across my neck.
Running his hand up my back pushing my shirt up with it he quickly pulls it off throwing it behind him.
I watch him clench his jaw, his eyes running up and down the new found skin. Deciding he has had enough he looks back up at me pulling me roughly to him by my belt loops. Kissing me he wraps his long fingers around my thighs squeezing softly to get his point across. I jump up wrapping my legs around his waist him once again pushing me back into the wall.
Pressing his lips roughly to mine he bites my bottom lip. Denying him entrance his grip on my thighs tightens making me gasp.
He smirks and softly runs the tip of his tongue across mine. Softly biting my lip he backs up carrying me down the hall to our room.
As soon as we are in the room I quickly find my back on the bed as he throws me down. Looking down at me he reaches behind him, pulling his shirt over his head just to throw it to the side.
Climing over my frame he slowly kisses up my stomach stopping at my bra. Running his hands up my legs he stops at my lower back lifting my hips.
Looking up at me his eyes meet mine daring me to move. Keeping my hips in place he quickly unbuttoned my pants and slowly starts to pull them down. The whole time his eyes never leaving mine.
Sitting in the floor he takes off my shoes along with my pants letting them fall to the floor. Moving up he slowly runs his fingertips up my legs making me shiver. He kisses softly between my breast softly pushing my hips back down.
I shiver again as his fingertips brush softly across my hips following the trail of my panties. The tingles in my stomach move lower as his hand dose. I bite my lip waiting, instead of touching me he moves his hand down my thigh as he starts kissing down my stomach again.
When he kisses the line of my panties I bite my lip once again. Looking up at me a smirk covers his lips making me lay my head back.
I hear him softly laugh as he places softly kisses down my leg. I hiss in slight pain when feel his teeth sink into my thigh. Looking down at him I watch as he softly kisses the new found red mark.
Moving to the other side he sucks on my thigh his cheek brushing my panties. I bite my lip shocked at how much I felt just that soft touch.
Andy clearly taking note he moves to softly brush his nose along my panites. Even though it was threw my panites I could still feel as he softly pressed his lips to where my clit was.
I felt him smirk as a softly moan left my mouth, telling him how turned on I really was.
Moving up he kissed both of my hips then just above my bellybutton then once again between my breast.
Running his hands up my back he unhooked my bra, slowly taking it off. He quickly bends down to leave another mark just above my nipple. I gasp and moan softly as he plays with the other one. The pain from his love bites mixing with the pleasure of him toying with me.
Kissing up my chest he presses his lips roughly to, his tongue slipping into my mouth. I Don’t even bother to fight him, now only focused on the pleasure.
Sitting up he grabs my hips and flips me over. I blush deeply already knowing what he is wanting.
I get on all fours as I hear him finish undressing. A shiver runs up my back as he slowly slides my panties down my legs.
Kissing down my back and leaving marks all over my neck and shoulders he thrusts inside me making me gasps loudly.
I don’t even need to look at him to know he is smirking. My gasps quickly turn into moans as he quickly takes me roughly from behind. Grabbing my hips to hold me still I grab the sheets tightly as his fingers dig into my skin.
There was no doubt that there would be marks all over me in the morning.
Filling me roughly over and over I quickly find my release making my legs shake. Soon after I feel Andy twitch inside me, us falling over in a pile of sweaty limbs tangled in each other.
Wrapping around Andy I lay my head on his chest my eyes feeling heavy.
“Nikki.” He says his voice rough.
“Hmm?” I ask looking up at him.
I’m surprised to find him holding a small ring in his hand, a red jewel set utop it.
I blush quickly understanding what he is asking. Looking up at his blue eyes he lifts one eyebrow as if that is his way of asking me.
“Yes?” I say unsure of my own voice at this point.
I can’t fight the smile that covers my face when I see the large one on his as soon as the word comes out of my mouth.
Taking my hand he softly slides the ring on my finger, then places a soft kiss on my nose.

“Happy birthday Nikki.”
