I Looked at the collie smiling at her.
"They told me you like it rough, I want to slam you and fuck you raw," I told her, in an attempt to sound dirty to her as she giggled, telling me she needed to get ready and get in character, still coming off as a sweet nerdy girl, telling me her safeword was 'Tennis balls'. I nodded, telling her to take her time as she asked where my bathroom was.
"Go down the hall, it's the door on the left," I told her as she smiled, walking off, carrying her backpack. I nodded as I turned off the TV, picking up the remainder of my pizza and putting it in the fridge before heading to my bedroom.
I thought I would set the mood for her, I previously had a girlfriend so I knew how to set an atmosphere, dimming the lights and lighting a few candles I had, tidying up my bed, which was probably gonna get dirty again. I bet she didn't care, you waiting to get to business but still, I wanted to make a good impression.
After Tidying up my bedroom I waited for this Lassie to come back as I decided I would head back to the bathroom to check on her, wondering what was taking the cub so long.
"Why do girls always take so long in the bathroom," I asked myself, approaching the door hearing the collie talk to herself as I peeked in, she was looking into the mirror, talking with her reflection.
"It's Okay Rachel, just let me take over," the collie said in a higher-pitched voice which sounded more childish and playful as she wagged her tail like she really did need to get ready, the two voices talked in a conversation. it was like this Collie really did have two personalities.
"Just close your eyes and imagine his throbbing member, ramming into you, that orgasmic rush as he rapes you, not stopping and filling every drop of sperm into our tight beautiful cunt" the childish voice said, snickering at the thought as the Collie, slid her fingers down her skirt.
"I bet it's really big," Her more normal voice said as the two voices seemed to be ready as I closed and knocked on the door, asking Lassie if she was ready, hearing her girlish snicker.
"I'm ready whenever you are mister, come in here and show me what a bad doggy I've been," she said, her childish personality taking over as she walked toward me, everything felt different, the way she moved and talked, the shy nerdy girl was gone and the new personality had an aura around her that screamed lust as she rubbed her hand on the crotch of my pants.
In that case, let's head back to my room" I told her, as she clung to me, sniffing my arm as we made our way back to my bedroom, she undid her clothes, standing before me completely naked as she pounced on my bed.
"Come here, and punish me, rape me, make me your little cocksleeve" Lassie begged, shaking her body as a felt conflicted about taking advantage of a girl with two personalities but I was already in deep, as I got behind her, undoing my pants, my erect piece popping out as her eyes lit up.
"Mister, It's so big" she replied in amazement as grabbed her side, lining up the tip to her already moist vagina and plunging it in. She wanted me to be rough so I would, slamming myself back and forth as I pinned her to the bed, our fucking had begun
