Chapter 3

One the way home the girls asked their father to stop by a store so he could purchase the strap on that the doctor had prescribed. Once he found one he went in first and asked the owner if he could bring in his daughter too. Of course he told him yes ... giving him the biggest of smiles!

“See girls here are the strap on cocks we have for sale. I assume you want one to use to peg your father here ... am I correct?”

Once again it was Robin that spoke up. “Oh yes, our doctor told us to have daddy purchase one so we both could fuck him. I think she too called it pegging. What is that exactly?”

“Well sweetie, it is when a woman or for you, a girl puts on the strap on cock and then gets behind the man or boy she is going to fuck. You would get some lubricant and grease up their asshole. Then you grab them by their waist and push the strap on cock into them. Even if they yell, don’t stop! You are in charge at that moment and you will need to provide your dominance over your new little pussy boi. Well in this case your new pussy daddy! Would you like to practice here so you know you are doing it correctly?”

“Sure,” Sara said, “We want to do this correctly with daddy. We don’t want to hurt him but when the doctor was finger fucking his asshole he shot his cum so quickly! She said that proved he likes it and needed to be fucked like a girl too!”

So he had the girls strip naked and he help put the strap on around Sara, being the oldest. He walked her through the entire process up to and including helping her grab his waist and drive it in hard.

“That’s it sweetie, fuck him like he is your little bitch. He loves it and wants you to fuck him hard. Just look his cock his rock hard and he is dripping right this second!”

“Oh daddy this feels so good. He picked out a strap on that also has a smaller cock that fits inside my pussy. Oooh daddy, it feel so good pushing into your asshole and feeling it pushing into me at the same time. I’ve got the entire cock inside you. It is fully inside your ass daddy. Can you see Robin, my god it is all the way in him!”

“Hurry up Sara I want a turn too! Let me put it on.”

“Sweetie, I don’t think your big sister is in any hurry to stop fucking your father. So if you want you can fuck me at the same time.”

He stripped and then put another strap on her the youngest daughter. Then he bent over and spread his ass cheeks. He told you to just push it in as hard as she could and then just fuck him hard and deep!

“That’s it darling, just shove it in me! Oooooh yes you are doing just fine. Keep fucking me hard ... yes harder and harder. Slam that cock into my pussy! Now girls swap ... each of you pull out and switch places. Little girl now it’s your turn to fuck your daddy’s pussy. Fuck him hard ... really hard!”

Both men shot their cum down onto the shop’s tile floor. The girls were so impressed with how well they were able to fuck these men ... one of them being their own daddy.

“Daddy I made you shot your cum onto the floor. Just like you did in the doctor’s office when you fingered your asshole. You like having your ass fucked don’t you Daddy?”

Tom pulled his pants up and asked the girls to get dressed. It was only then he noticed that there were over 20 people standing around the Sex Shop that had been watching his girls fuck him and the store owner. He also saw several that were still holding their phones taking videos of this entire event. He could only hope they would be kind and use them just for her personal pleasure.

On the drive home Tom began speaking to his girls.

“You two are something. I thought we were just going to the OBGYN office to get you checked out and get your new prescriptions. But things went a lot further than I had expected. I had no idea you would share with the doctor about wanting me to fuck you both nor did I ever dream of her giving me an examination. And what was that with the Prostate Exam ... why did she do that I wonder?”

“Any way, now that we have purchased the strap on dongs I need to girls to promise that you will leave them at my house. If you mother ever found them in her house she would shit a brick! This has to yet another secret for the three of us ... promise me girls!”

“And I need to two to promise that you will only use these strap ons just once in a while on me. Yes they felt good but this was to be about you girls learning about sex. Fucking me isn’t what you need to learn. I should be fucking you beginning next week. The doctor said you each needs about 5 days for the birth control pills to take effect. So we have to wait.”

“That’s fine daddy. Tonight after supper how about we get naked so I can suck on your cock this time. Robin jumped right in and gave you her first blow job and got your cum down her throat. It should be my turn tonight! Robin while I am doing that you can either eat my pussy or you can sit on daddy’s mouth so he can eat you. But be careful sis. Dad might not be ready for your piss in his mouth!”

Sure enough after the three of them ate and then relaxed watching some TV they moved to his bedroom. Tom stripped and lay back on the bed. Sara quickly moved in between his legs and took his cock in her hands. She began sucking on his cock just as Robin moved up and sat on her daddy’s mouth. She kept moving between having him eat her pussy and her butthole. He didn’t seem to mind which one he was eating so she kept at it.
