A few nights after my initial hook-up with Sophie and we still hadn’t even talked about what happened. But one day everyone else decided to go out for dinner or meet friends elsewhere, leaving the two of us alone at the house for a few hours in the evening. I decided a hot shower was in order and when I was done I found Sophie in my room.
She was only wearing a sexy thong and nothing else. “I didn’t get to taste your cock the other night and it’s all I’ve been able to think about,” she said softly. She stood from my bed and walked to me. She kissed my briefly before removing my towel and letting it fall to the floor. She took my cock in her hand, almost as if she was feeling its weight. Then she dropped to her knees and took me into her mouth.
My cock was instantly hard. Her tongue wrapped around my shaft hungrily. I moaned as she fonled my balls and sucked harder, “You’re such a fucking slut, Sophie. You like having my hard cock in your mouth don’t you?” She hummed an affirmative through her mouthful of my dick.
I grabbed handfuls of her hair on each side of her head and pushed her face farther onto my cock. She gagged for a second before adjusting to me in her throat. Once it seemed like she was used my positioning I starting moving her head up and down and on my cock. Her tongue worked around my length the whole time expertly. I could feel my orgasm building and I knew I wanted to cum in her mouth.
“Oh fuck, I’m gonna cum. Do you want my cum in your whore mouth, Sophie?” I moaned. Instead of answering she grabbed onto my thighs pulled herself deep onto my cock, gagging slightly. I gasped at her eagerness and thrust my hips towards her face.
I came with a grunt and shot my hot cum into her mouth. “Swallow it like a good slut,” I commanded as I pulled my dick out of her mouth. She gulped it down hungrily and cleaned my cock with her tongue, leaving no trace of cum anywhere. “You’re such a good little slut for me, baby. If you promise to be good then maybe I can give you good fucking again this weekend.”
