He sounded very pleased with himself as he described the pleasure it had given him to relieve himself in my ass, and how much more it was going to give him when he filled my cunt with his cum as well. By this point, I was equally aroused and uncomfortable. We had spoken of this type of play before, but had never experimented with it. Daddy assured me that today was going to be the day my curiosity was satisfied.
As his cock plowed into my soaking cunt, he described to me some of the things he had in store... his work day was light, and he only needed to go in to the office for an hour or two. Daddy said that like all good equipment, I needed to be properly maintained to be in my best condition. Today was going to be my maintenance day.
Daddy fucked me harder, deeper than I think he ever had... as my breathing grew ragged and my clit swelled, he hammered into me with a fury I relished. I felt his balls tighten and his cock begin to spasm as he shot spurt after spurt of sweet, hot cum deep into my cunt. He groaned as he collapsed against me, lying against my back for a minute while he gathered his strength again.
He pulled his cock from my cunt, then took my training balls and slid them deep inside my quivering, oozing hole. Climbing on the bed in front of me, he held his fingers out for me to suck clean, then laid back and watched as I cleaned his cock as well. When I had sucked and licked the last of our combined fluids from his cock and balls, he slapped my ass again and warned me to stay in position while he showered and dressed for work. When he was finished, he would give me his instructions for the rest of the morning.
As I waited, used, ridden and filled with Daddy's fluids, my mind raced and my cunt twitched with anticipation for the rest of the day. I heard the shower shut off and the sounds of him dressing, and I knew this would be a day neither of us would soon forget...
