Dad reacted to my question with a hearty laugh while mom only giggled. Then dad said, "OK Hon, I guess, if you are ready, we can begin. My God, you're tiny and tight, you sure you want to go on with this? I don't want your first time to be painful, maybe we should postpone all this 'til we can figure out a way that won't hurt so much."
I responded by bumping my groin up against dad, driving his big cock even further into me. Dad was right, having his big cock deep inside me did hurt like hell. We stayed still for a little bit, I brushed away a tear that threatened to run all the way down across my face and, in a moment, the thrill of having my pussy invaded for the first time made the pain a lot more bearable. Finally, I realized I could feel dad's cock throb with a faint pulsing and made a tentative upward thrust.
Dad responded with a very gentle in and out flexing of his groin. I experimented a bit at first but quickly discovered I could easily match each of daddy's thrusts with bucking responses of my own and soon experienced an orgasm that, while not mind wrenching, made me feel all warm and soft inside. Dad continued his gentle in and out sawing and I soon felt my insides begin to quiver and knew that another orgasm, more intense than the first would soon wash over me. Fucking his daughter must have been doing something nice for dad for there was a slight change in the rhythm of his thrusts. His breathing became more labored and somehow, I sensed that he was getting close to the release my friends had told me was inevitable.
At about the same time I felt dad's cock become even more rigid and thicker than ever, I felt mom's fingers rub across my anus. She quickly thrust a finger into my virgin anal opening, causing me to exhale sharply; Our sex ed teacher never mentioned anything at all about anal penetration but, in a moment, my surprise was replaced with the realization that I really liked what mommy and daddy were doing for me and instinctively raised my legs behind dad's butt and convulsively thrust upward and drove him deeper inside me. The dual penetration was all it took to push me over into a mind shattering, trembling orgasm that left me breathless. After cumming again, a soft warmth flowed over me that matched the heat of the spurts of hot cum dad was pumping into me. A moment later, the shear volume of cum more than filled my cock stuffed pussy and some dribbled down onto mom's probing fingers.
Dad's climax did nothing to diminish his erection and when he withdrew, mom quickly grasped and guided him to my cum covered anus. Dad looked anxiously toward mom and said, "Julie, do you think Bobbie is ready for this?"
My eyes were focused on mom's face when she replied, "I think so but what do you think Bobbie? Want to see how great it feels to have your dad slide it into your ass? You are as ready as you are ever likely to be and I think you will like it, I know I do."
I grinned and said, "Okay mom, if it works for you, it'll work for me. "Dad, if you are up for it I guess, like mom says, there'll never be a better, huh?"
With a look of concern, dad said, "Okay Hon, I'll go just as easy as I can. The moment you feel discomfort tell me and I will stop."
Mom was still grasping dad's cock and using it to smear cum around my anus while we talked and when she heard my assent, she guided dad into my anal passage. Dad leaned down and kissed me then gave his dick a nudge that sent the crown of his dick in past my sphincter. I inhaled sharply, not in pain, but in wonder at having my rectum filled so delightfully. I recovered quickly and said, "God Daddy, you're big, but it feels sooo good, you can push on in further if you want."
Ask and ye shall receive I learned once and the words were no sooner out of my mouth when I felt more and more of dad's monstrous pole slide deeper and deeper into my backside.
Dad's pubic hair was pressed tightly against my dripping slit when he had no more cock to give me. I looked up at him and smiled to let him know that I thoroughly enjoyed what he was doing to me. I glanced toward mom and looked into her anxious eyes, grinned and said, "Mom, I hope you know you have unleashed a monster. I had no idea getting it in the ass could feel this good."
Mom grinned and said, "Somehow Bobbie, I knew you would enjoy this. Now shut up and fuck your dad but don't wipe him out totally. I still have two or three places available."
Mom slid her hand in between dad and me and a moment later slid a couple fingers into my pussy while dad continued reaming my asshole. The double fucking sent me to a plane of eroticism that caused me to throw my legs wide the better to accept all that mom and dad could give me and then it was all over. Everything came to a crashing orgasm that left me gasping while pumped jet after jet of hot cum way up inside me.
Afterward, the three of us sighed in utter contentment, dad leaned close, kissed me on the mouth and said, "Thank you Bobbie, that was the second nicest experience of my life. He grinned and drew mom tightly against us and added, "You Julie were first and the very best." He gave me a quick hug and another kiss and said, "Sorry Bobbie, but that is the way it is."
With that, we got off the bed and went into the bathroom to clean up for bed. I turned on the hot water tap and reached for a face cloth but mom stopped me and said, "No Bobbie, allow me. Your dad isn't the only one that gets to have fun with your body tonight." She hesitated a moment and added, "Not that I haven't had my share of fun too."
A moment later, waves of warm pleasure washed over me as mom, with a hot, wet facecloth in hand, cleaned the remains of dad's cum and my own fluids from my pussy and butt. She rubbed, scrubbed and played with my clit and labia until I threw back my head and shouted, "Oh my God Mom, I'm cumming again, oh YES, YES!"
My release was accompanied with pelvic shudders and twitches that did not subside until mom finally removed her hand and the facecloth from my warm, wet groin.
Mom leaned close, kissed me on the mouth and turned her attentions to wiping all evidence of our fucking from dads, by now, limp cock. Then she kissed him on the mouth and gave him the dueling tongues treatment as well. They broke apart and mom rinsed the facecloth once more and proceeded to give her pelvic region a thorough scrubbing. She giggled and said, "Tom, I thought I would provide a squeaky clean place for a snack should you be hungry after fucking Bobbie the way you did." She laughed, gave dad's cock a tug and said, "Maybe licking my pussy will do something good and you will be want to poke this beauty into one of my holes."
Dad grinned, slapped me on the butt and said, "Ok Bobbie. Off to bed with you. You are much to young to see any of the nasty stuff your mother and I do."
I turned to leave for my room but couldn't resist looking back to say, "Yeah, right. Right after you have fucked me royally a couple of times." I smiled to let both mom and dad know I was only having fun. Mom gave me a kind of sharp look, but then smiled sweetly and waved me off to bed.
