"God Kurt you are, mmmh, so fucking tight!" He moaned into my ear.

I bit down on my lower lip as I felt him thrust his big dick into me again. He thrust harder than usual; it felt like the tip of his nine inch cock was stabbing my prostate. I tightened my legs that were wrapped around his slender waist. He had me against the wall in the handicap bathroom stall at this posh restaurant that had just opened up in Lima, it was called Nine. As he attacked my prostate again I clawed at his back and bit down harder on my lip.

"You like my cock in you don't you Kurty?" He whispered, mainly to ensure no one heard us, but somehow it was the biggest turn on.

I nodded. "Yes, I fucking love it in me."

Mentally I slapped myself for sounding like some kind of wanton slut that was getting fucked in the bathroom. Although I was getting fucked in a bathroom, I defiantly wasn't a slut.

"Damn babe, I'm gonna cum. Fuck Kurt you're gonna make me cum!" He said in my ear.

I pulled my head from the tile wall and leaned toward him. "Cum for me Cooper." And then I captured his lips with mine and began to kiss him deeply. I moaned into his mouth instantly and allowed him a place to slip his tongue.

Not soon after I felt him tremble as he continued to thrust in and out of me and hold me up with his strength. I could tell he was close, so I tightened the muscles in my ass and tugged on my own hard cock. I started to cum all over his stomach and chest, and I felt him fill me up with his warm cum. I pulled away from kissing him and rested my head against the wall as I tried to regain my breath, and my composure. Cooper pressed his forehead against mine and breathed in and out hard.

"That was so fucking great Kurt." He said just above a whisper. He began to butterfly kiss up my neck until he started to suck on a sensitive spot right below my ear.

I pushed his head away and shook my head. "I already told you Cooper. We can have sex and we can kiss and we can go on dates but you cannot leave any marks on me. I bruise easily and if I go home and he sees a hickey on my neck I'll be dead."

"What's the worst he can do?" Cooper asked, still supporting me. "Throw you out of the house?"

I rolled my eyes and untangled myself from him, and managed to slip his cock from my body. "Yes, that is exactly the worst that could happen!" I reached down and grabbed some toilet paper from the roll. "If he finds out he will kick me out and then you won't have to worry about leaving bruises on me because I'll be homeless."

Cooper walked behind me and wrapped his arms around my waist and pulled me against his chest. "I already told you that you can live with me." He kissed my neck again.

I couldn't help but lean into him. I smiled at the sweet words but then shook my head. "Coop, you're on the verge of becoming a big time music producer, you do not have time to try to keep me happy in your house. Besides, I love him."

He chuckled into my ear. "You may love him, but you love my cock inside of you ten times more." He bit my earlobe and sucked into his mouth.

I couldn't help but giggle. "Cooper Anderson, I must say you are absolutely vulgar."

"Another thing you love about me." He said before kissing my cheek one more time and then taking his arms from around my waist.

He walked to the pile of discarded clothes and picked up his Calvin Klein boxer-briefs. He slipped the tight garment on and then started to redress in the black suit he had worn tonight. I cleaned myself off and then started to get dressed myself. The entire time I could feel the older man staring at me. I looked up and saw his crystal blue eyes staring at me. He smiled and then walked up to me.

Grabbing my face, Cooper kissed me. He pressed his soft lips against mine and worked them slowly. I caught on to his pace and rhythm and went with it. His hands slipped to my back and then even lower to cuff my butt. I moaned into the kiss and he took the opportunity to slip his tongue in. He explored every inch of my mouth and then pulled back to get air.

I opened my mouth to speak but the sound of the bathroom door opening alarmed me. The man in the stall next to us began to pee and the noise was overbearing. I tucked my shirt into my skinny jeans and made sure I looked okay to walk out.

"I had a good time, tell my brother that I said hi." Cooper leaned down and whispered into my ear, loud enough to hear over the man peeing, but low enough to where only I heard. "I'll call you later and we'll plan sometime."

I nodded and gave one last peck on the lips. I then opened the stall door and slipped out. I walked through to restaurant until I was back to the front. There, Blaine Anderson, my boyfriend of four years, sat on a waiting bench. His black hair was slicked back perfectly and his outfit—a black blazer with the sleeves rolled up with an orange and yellow loose t-shirt under, tucked in, and black skinny jeans—was pristine. He looked up when I approached him and smiled.

"Hey are you alright?" He asked with worry in his voice. "You were in the bathroom for a long time."

I nodded and pushed my hair back. "Yeah I'm fine. There was a line, surprisingly, and I was unfortunately the last one in it. They don't have urinals in there, only four stalls. So there was a wait." I smiled and shrugged.

He nodded and wrapped his arms around me. "Oh okay good, I was getting worried. Come on, they have our table ready."

He led me toward the dining area and as we passed the hostess booth, I saw Cooper slipping out the front door. He looked my way and smirked deviously. With a wink, he disappeared.
