Fifteen minutes pass by until the girls come back to the living room hand in hand. They are both blushing and their heads are lowered, avoiding my gaze.
"Already done? There is no need to rush, take your time", I say, smiling at them gently while remaining seated on the couch.
At my subtle nudging, Ella gathers her courage and raises her head.
"Hmm, d-daddy, actually… well…",
Poor Ella is opening and closing her mouth like a fish, the words that they rehearsed beforehand are not coming out.
I put on a slightly puzzled expression and ask,
"What's wrong, honey? You know you can tell daddy everything".
With a deep breath, Ella tries again,
"W-well daddy, uhm… Rosie h-has a problem again".
"Ehm, by saying 'again', you mean that she still feels… 'funny'"?
Ella exhales, glad that I understood what she meant.
"y-yes daddy…".
I turn my gaze to Rose,
"Is that true princess? You feel the same way as you did two days ago"?
Rose rises her completely flustered face to look at me, but quickly averts her eyes.
"Y-yes daddy, I am sorry to bother you again, b-but… could you help me again"?
I motion with my hands and both girls come closes. I wrap my arms around their waists and bring them close to me.
"Princess, I told you before, daddy will always help you. There is no need to be shy about it".
They both hug me happily, muttering 'thank you daddy', as always in tandem.
"Ella, do you want to take part too"?
Ella squirms a bit at my question. In theory, the one that need help is Rose, so she can't come up with an easy excuse to cover the fact that she is horny as well.
I chuckle and ruffle her hair,
"Honey, we might be doing it to help Rose, but the fact is that it is enjoyable for both you and me. There is nothing wrong with enjoying each other's love".
Ella freezes,
"L-love? Wha… what do you mean daddy"?
"Honey, love is what makes the therapy effective. If I didn't love Rose, I would have been unable to help her. Your love also contributed to that. You do love your sister, don't you not"?
"Well, yes daddy, it's just… I didn't think about it".
"Well it is, that's why Rose had to accept me as her daddy and I had to accept her as my daughter to help her".
"I… I see".
"So, neither of you has to worry. You can ask me anytime. It doesn't matter if you feel sick or not, daddy will always be willing to be with you and make you feel good, just as you make daddy feel good".
The girls blush a bit, as my words reveal that I already knew what they were up to, but then smile happily, as I just gave them a free 'I-am-horny-as-fuck-daddy' pass.
"So", I say, "How about we start here in the living room and then we see where it goes"?
"Yes, daddy"! What a happy/horny chorus.
I instruct the girls to take off their clothes, and they do so immediately, before rushing again in my arms. Here I am, sitting on the couch, with a naked cutie in each arm. My hands grab a tit each and I start playing with them; my head turns to Rose, and plunges in for a deep kiss. Rose reciprocates, entwining our tongues and getting really into it, while my hands give both of them a breast massage. I kiss Rose for a bit, before shifting to kiss Ella, who eagerly locks my mouth with hers. I keep alternating between my daughters for a while, before disentangling myself and standing up.
"Girls, how about you take off my clothes".
"Yes daddy!" (X2)
I already took off my jacket earlier, so the girls work together to unbutton and remove my shirt, their hands running over my chest. Rose, the little twerp, starts licking my nipple. Damn, she is good… Ella sees her little sister's actions and to not be left out, attacks my other nipple with vigor. Ohh, having your nipples licked while holding on two teenagers' juicy asses really feels great. I let them do as they please for a bit before saying,
"Now, now, girls, I am still half dressed".
They both immediately stop and smile at me impishly, before replying in unison,
"Sorry daddy!".
Then, they both drop on their knees in front of me, and with expectant eyes, they unzip and lower my pants. My little daughters unconsciously lick their chops when they see my erect cock perfectly delineated on the fabric of my underwear. With a bit of a struggle, my pants are gone, along with my shoes and socks, and now the girls can finally concentrate on what I am sure will rapidly become their favorite part of my anatomy. They grab the sides of my underwear together, and with now semi-expert motions lower them and take it off. My cock greets them by twitching in thier faces, making my babies giggle.
"Well girls, since you are already in front of it, why don't you go ahead"?
The girls don't need to be told twice, they don't even reply, as Ella grabs my cock with a hand and starts licking the shaft, while Rose dives under it and starts sucking my balls. Neither of them is breaking eye contact with me, as if they want to see the result of their efforts. I put my hands on their heads and leave them there, without pushing, just making my presence known by touch. I look at them working on my cock happily and smile in satisfaction.
The blowjob is quite good, if amateurish, but I don't mind, I have all the time in the word to train them. I use my hand on Rose's head to make her stop sucking my balls, then I motion her to stand up and I start seriously making out with her, while my other hand guides Ella's mouth on my cock-tip. Ella obliges to my silent instructions and places her lips on top of my glans in a hot wet kiss, before sliding my cock inside of her mouth slowly, managing to take 2/3 in at the first try.
Damn, I am impressed. As she starts bobbing her head on my cock, sucking and licking all the way, I concentrate my attention on Rose. I lower my head from our kiss and bite her nipple lightly, causing her to moan, before bringing my mouth next to her ear and whispering in a level of voice easily heard by Ella.
"So, you girls thought you could bully your daddy, uh? I guess daddy will have to punish you a bit".
I slap her ass as I say so, before grabbing a buttock and squeezing. The slap had almost no power behind it, I don't want to hurt her after all, but still causes a very cute "Kyaa!" to escape her lips.
My punishment however has not started yet. The slap was only to grab her attention…
