I am the alphas mate

I was grabbed by the arm and pinned against the wall, I gasped in shock as I looked up to see the dude from earlier, "what the h-" I was cut off when he placed his finger over my lips and shushed me, "Mine" he growled. yes growled, I mean who growls. Before I could respond, he smashed his lips on to mine and ravished them. Instantly a strange spark ignited inside me, tingles erupted on my lips. I suddenly felt this uncontrollable pull towards him, like he's meant for me. Why do I feel like this? I felt his hands grab my hips and pinned me harder against the wall with his body.
Before I knew it I was kissing him back. His hair was wrapped around my fingers as I pulled his lips closer to me. One of his hands stayed on my hip as his other hand, slid down to my thigh, his thumb, rubbing circles in a spot, sending shivers up and down my leg. His tongue swept into my mouth, exploring the interior. My eyes widened when I felt something very prominent against my stomach. I pushed him away and I began to panic. Suddenly, the sound of my smack against his cheek filled the empty hallway.
