Despite her embarrassment the previous night, Katie didn't slack off in her agreement to wear more attractive clothing around the house. The next day, she wore a simple t-shirt with no bra that hugged her oversized breasts and fit snugly at her small waist. The shorts she chose accentuated her fantastic ass.
After dinner, Elaine brought out some vitamin E cream, saying that it was good for the skin. "It's the best thing for bruises and scars," she explained. "Katie, I need you to put the cream on every night from now on to get rid of your stretch marks. Daddy will supervise to make sure you do it right."
A couple of hours later she practically pushed me into Katie's bedroom to "supervise" putting the lotion on our daughter's big tits. "Do it right, Daddy -- I don't want you to miss so much as a square millimeter. And then I want you to come back across the hall and fuck the shit out of me."
"Why are you doing this?" I asked, truly mystified.
She reached down and began stroking my cock as she answered. "Isn't it obvious? From the moment you saw our daughter's fantastic, fuckable little body, you've been hornier than I've seen you since our honeymoon. I don't care whether it's because she gets you revved up or that maybe you just feel guilty as hell for being so attracted to her. All I know is that ever since the night she put on that damn swimsuit you've had a perpetual hard-on and you've been fucking me like a jackhammer."
She jacked my cock through my pants as she continued, "I love it. I fucking love it. I love your nine inch dick. I love the fact that you're going crazy with horniness. So go out there and cream your daughter's tits. Then come back to bed and fuck my brains out."
"You really don't mind if I . . .?"
Elaine unzipped my pants and yanked them down so that they were pooled at my ankles. She stroked my meat as she continued: "Do I mind if you spend the next half hour playing with your daughter's big tits? Do I mind if you cover your teenage daughter's humongous, sexy tits with your spunk? Do I mind if you stuff your hard cock in her obedient little mouth, coat her tonsils with cum and pump your cum straight down her throat? Do I mind if you turn her into a submissive little Daddy's girl who whimpers for Daddycock? Ooh! That last one made your cock pulse, didn't it?"
She knelt at my feet and started licking up and down my shaft. "All I ask," she said, and paused while she engulfed my cock in her mouth for a moment and then came up for air and resumed jacking me off with both hands, my cock pointed straight at her face a couple of inches away, "is that you not fuck her."
She slid her wet tongue along the entire length of my rod and swirled her tongue all the way around the tip. "Play with her tits." She slurped my cock. "Diddle her pussy." More slurping, and then she rubbed my cock all over her face. "Make her scream for your big Daddy dick while she titfucks you. Teach her to revel in the taste of your cum and the feel of your cum on her face." She grabbed both my asscheeks with her hands and deepthroated my cock for a full minute, plunging her face over and over into my pubic hair and then out all the way to the ridge of my cockhead. Finally, she pulled me out again so that she could talk. "But the only pussy that your cock should penetrate is mine." She kissed the tip of my cock reverently and looked up into my eyes. "Let her stay a virgin, at least technically. And when you get so horny you need to thrust your cock in a tight wet pussy -- come to me!"
Who was I to question her after that? Sure, I still felt pretty goddamn guilty not only for the incest thing but also because I was taking advantage of Katie's passive, compliant nature. But the fact was that Elaine was right: I was horny as hell. Every time I looked at my daughter I wanted to pull out my cock, throw her on the floor and fuck her. My feelings of guilt paled in comparison to my overwhelming lust. So I put my misgivings aside, threw on a bathrobe over my bare lower torso and knocked on my daughter's bedroom door.
"Sweetheart? It's Daddy."
When I entered, she was lying in her bed. Her hands clutched the covers up at her collarbone.
"I've come to see how you're doing," I said, "and to check whether you're using the vitamin E cream that Mommy bought for you."
"I can take care of it myself, Daddy."
"In other words," I said, "you haven't done anything with it yet -- I'll bet you haven't even opened the package."
"I'll use it tomorrow. I'm all set for bed right now."
I picked up the box containing the lotion, which was sitting on her night table, then sat on the edge of the bed and made a show of reading the label. "It says here that you need to apply the lotion every day to a bruise or cut, as well as to the region surrounding any inflamed area," I said. "If you want to avoid any unsightly marks on your chest, you need to start using this stuff sooner rather than later."
"Oh, Daddy. Can't you just. . ."
"Your mother and I are only looking out for your welfare, sweetie." I took hold of the edge of the coverlet and gently took it out of her hands, then pulled the sheets down to expose her in her old green nightgown.
My cock started to harden as I pulled her nightie up, first past her toned thighs, then beyond her trimmed pussy, and past her flat stomach, finally exposing her delicious breasts.
I poured out a generous dollop of the vitamin E oil into my hands and rubbed them together to warm the oil.
"Daddy, please don't. . ."
"Don't what?" I began caressing my oily palms against the sides of her massive tits where the stretch marks were. "Don't take care of the daughter I love so much? Don't do everything I can so that she looks her best, so that she can walk confidently through the world?" The massage now went beyond the sides of her tits. The vitamin oil all over her funbags glistened in the yellow light of the incandescent bulb by her bedside.
"Daddy, please. It feels . . ."
"Does it feel good, darling? It should. It's so good for you." My hands alternated between manipulating my daughter's huge, soft tits versus pinching her engorged nipples. "So good. Daddy wants his baby girl to feel so good."
"Yes, Daddy, but is it supposed to -- Aagh!" Katie shivered so suddenly it was like an electric jolt ran through her body. I looked at her wonderingly -- my daughter had just orgasmed merely from having her breasts fondled!
I thought back to the other night, when I'd seen Katie shiver repeatedly while her mother and I played with her tits. Looking back, I realized that Katie was having little mini-orgasms repeatedly just from the sensation of having her breasts touched by us. In all my years of sexual experiences, I had never encountered any woman whose breasts were so sensitive. This was going to be even more fun than I'd first anticipated.
I tweaked Katie's nipples again and she spasmed again. "Ooh, Daddy!" she whispered, "I don't think it's supposed to feel quite like this!"
