After participating in the wildest sex I've ever had, I was bushed and dozed off for a while as I lay on the floor. I did not stir until I heard voices and looked up to see Rickie and Debbi sitting on the couch, both naked, talking about Debbi's tits. Rickie was saying he thought that Debbi's tits were bigger than mine but that I had bigger nipples. Debbi had a hand under each of her tits and was lifting them for Rickie's close inspection, she was rubbing her index finger across each nipple trying to get them erect saying, "See Rickie, my nipples get large when they are erect, just touch them and see!"
Rickie reached over and pinch her nipples a few times then leaned down and at first started licking them, then he opened his mouth and began sucking on her nipples. Debbi held his head against her chest as her brother began taking as much of her tit in his mouth as he could. Meanwhile, his dick was becoming very erect and when Debbi noticed it, she reached down and began stroking her brother's cock. As I watched my twins interacting, I was thinking these kids are going to be fucking each other all the time. Almost immediately after thinking that, Debbi, while maintaining a hold of her brother's now hard cock, threw her leg over Rickie's lap and guided his cock into her pussy. She began riding his cock while Rickie continued mauling her tits, they were going at it like there was no tomorrow. It didn't take long for both of them to experience yet another orgasm, I don't know how many times these two have had orgasms today, but it's been a bunch, especially for novices.
Henry was starting to wake up just as the kids were coming down off their sexual highs, Rickie was grunting as he pumped his last couple of cum shots into his sister's pussy. Debbi remained sitting on her brother's lap with his cock fully engaged in her pussy, she said to Rickie, "I don't want to get up, I like having your cock stuffed in my pussy, it feels so good." As she sat there sliding her pussy up and down his shaft, she continued, "I didn't know fucking would feel so good and be so much fun! I hope you and Dad will always want to fuck me!"
I thought, who wouldn't when you are being fucked by guys with an extra big cocks. Someday she will find out the difference when being fucked by some guy with a small dick. This brought to mind what our new neighbor, Alexis, was confiding to me a few days ago. She said that she was a virgin when she got married and has never strayed. Her hubby, whom she says she loves very much has a really small dick; she knows she is missing out on a lot of sexual pleasures but doesn't know quite what to do about it. She is a very attractive woman and so I was hesitant at the time in suggesting that my husband would be willing to show her what she's been missing. But now that I know my son is so well-hung, I may suggest the next time I see her, that she should let Rickie fuck her so she knows what it's like to be fucked with a well-hung dude. That would be hitting two birds with one stone, giving Rickie more experience, and giving Alexis the pleasure of being fucked by a guy with an extra big cock.
I suggested to Debbi and Rickie that they should cool it until bedtime. The rest of the evening we were like a regular family, watched some TV and I made an ice cream snack for everybody. At around 9 pm, Henry was getting tired and said, "I don't know about you guys but I'm ready to hit the sack. So who's going to be my bed partner tonight?"
Debbi spoke up saying, "I would like to Daddy, but can I sleep with Rickie tonight?"
Henry said, "Ask your bother!"
Rickie said, "Sure, your bed or mine?"
Debbi laughed and said, "Let's start in my bed!"
Rickie just smiled saying, "Okay, your bed it will be."
Henry got up and gave Debbi and me a kiss goodnight and headed for our bedroom, I told him I wouldn't be far behind him. I stayed up and talked to the twins for a while telling Debbi to be sure and take her morning-after pills and that I'd make a doctor's appointment so we could get her a birth control prescription. I said to Debbi, "The last thing we want right now is for you to get pregnant sweety, I don't want your brother or your father or any other man knocking you up!"
Debbi said, "Who else other than my brother or dad will be fucking me?"
I retorted, "Well, for certain there will be your uncle Bob and if you are willing, I'm sure your grandpa will want a piece of your ass along with your boyfriend. Then there are the men in our swingers group I know would love to fuck your sweet little teenage pussy. So Im guessing that just over the next few months you will have quite a few guys hankering to get their cocks inside your pussy."
"Oh Mom, do you really think that will happen?"
"Baby, you're going to be spreading those pretty legs of yours many many times! So like I said, let's make sure you don't get pregnant until you're ready to have a baby."
She looked at me with a puzzled look on her face and said, "Mom, are you thinking about having any more babies?"
"What made you ask me that?"
"I don't know, but I heard you say from time to time that you initially wanted three kids and there are only two of us."
"Yes, I did say and initially, I did want three children, but after you two were born, I decided raising twins was enough."
"So you don't want a third child?"
"I've thought about it a few times, but no, you two are enough."
