I begin to lick him from the top of his ass all the way to his balls, taking his cock down my throat every now and then as well. I can feel his body relax more and I continue to give him the rimjob, I knew this would work. He raises his legs and rest them on my shoulders, giving me unrestricted access to his hole. I trace the outer circle of his hole with tongue, slowly circling it and making a spiral shape leading to the inner circle. I push my tongue into his asshole and I hear him moan a deep, load moan. It makes me so horny to hear him moan and I start playing with myself. I go back and forth between tracing light circles around his hole and then penetrating it with my tongue while I use my hand to play with my clit.
I feel his hot and heavy balls against my forehead as I tongue fuck his asshole. Feeling them there reminds me of how badly I want his cum. I take my hand off my clit and wrap it around his cock instead, using the wetness from my pussy as lube for the handjob. I feel his balls twitch as I jerk his cock while kissing his beautiful asshole.
"Sir, will you please cum for me?" I ask, desperately hungry for your big load of cum.
"You're Sirs little cumslut aren't you? You love begging for my cum." He says to me as he places his cock in my mouth. "You may have my cum. And you better not drop any of it."
"Yes Sir!" I am barely able to get the words out before he grabs my head and starts fucking my face. The rimjob made him so hard and the tip of his long, thick cock is reaching deep into the back of my throat. I choke on his dick and moan around it as he uses me as his fuck toy. He buries himself as deep in my throat as he can and I feel the hot sperm coating my throat. He pulls back and little and my mouth fills with his huge load. He collapses back on the couch and I open my mouth to show him all the hot sperm inside as his take a picture of me, his little cumslut pet, face a mess from eating his ass and mouth full of cum. He instructs me to swallow and I do. I clean his cock off and he recovers from his orgasm. He drifts to sleep as I lovingly lick him clean. I wake him up and guide him to the bed, feeling fulfilled as his pet and ready to serve him again tomorrow.
