Pleasure & Confusion

I pulled my top down and brought his lips to my tight nipples and he sucked on them and gave them a soft bite that made me quiver and moan. He knew I liked it and immediately pulled my bottoms down. "Let's see how wet you are" he softly said. He stuck two fingers inside me and it made my whole body relax as he curled them in and pulled them out again, revealing two very sticky fingers. "You want more ?" I nodded and pushed his hand back inside of me as he pushed them in slowly and deeply inside me. Then he turned his hand over and it made me moan when he came down and began to suck on my clit and get me closer and closer to an orgasm. I pulled his head up and stroked his hair, all I wanted was his cock. He began to get harder and I got more and more anxious. "Please put it in me" I pleaded but he told me to be patient. I could do that and he didn't disappoint when he slowly stopped eating me out and jacked himself off in front of my opening. It was so hot as he fingered me deeper and harder I thought he was never going to put it in me when he flipped me over with my legs and fucked me hard and deep. I gasped when he entered me because of how veiny and ribbed his dick felt inside me. He clenched my nipple and twisted it making me moan. I was confused because I was in love with another shifter who loved me equally. My wolf recognizes him as my mate too. How can this be possible? How am I going to deal with this?
