The next day I went to the hardware store and bought a new door knob and a few odds and ends. When I got home, I pretended to work on the door for a while after dinner, but then gave up after a half an hour. "I think I got the wrong parts," I explained to mother and daughter. Marie didn't care much one way or the other, but Krissy just smirked. It was the first time she had given any sign of what had been happening at night.
When Marie started worshiping Daddy cock a little while later, I didn't bother trying to close the door. Instead, I let it drift wide open. And sure enough, a few minutes later Krissy came out with her folding chair.
No popcorn this time. Krissy was dressed in more normal bed clothes: loose little shorts and a comfortable top. If it wasn't clear from the start that she wasn't wearing a bra, it became obvious within a minute or two. While Marie focused on my cock and whispered Daddy endearments, Krissy reached up under her blouse and started playing with her big tits. "Are you a tit man?" she mouthed to me silently. She quickly lifted up the blouse giving me a flash of tits that lasted only a fraction of a second.
In response I thrust harder into her mother's mouth. "I love your tits," I said, reaching down to fondle her mother's fantastic rack. "Love my baby girl's big tits."
Marie took her mouth off my cock briefly, giggled and said, "Thank you, Daddy. They're just for you. Only you." Then she went back to kissing the length of my cock. Krissy blew me a kiss.
While Marie sucked my cock, Krissy got more active. With the rock music still blaring from her bedroom down the hall, Krissy caressed her big tits every way she could think of. Sometimes she played with her tits through the fabric of her t-shirt, other times she reached under the shirt and played with them under the cloth. Either way, all I could think of was how huge they were on her slim frame and how much I wanted it to be my hands instead of hers mauling her big tits and jiggling them in my hands. Marie gasped and shivered at my feet, experiencing another suck orgasm, and I pulled her head downward on my pole in encouragement.
Finally, at the end of one song, Krissy pulled up her shirt and bared her large breasts. She hefted both of them in her hands and shook her big tits at me as if she was offering them to me. Her mouth was open like she was laughing silently, but at the same time I could see that a big part of the sexual charge for her was that she knew she was only teasing me. The huge tits, the wide sexy grin -- you can look but don't touch, they aren't for you, she was saying with her eyes. Or were they?
I shut my eyes and shot a load of cream down her mother's eager mouth. When I opened them again, Krissy was gone.
The next morning Marie outdid herself: fruit salad with mangoes and papayas alongside scrambled eggs. "We need to keep Daddy in tip top condition, don't we sweetie?" she said to Krissy as she put the plate in front of me.
Sex that morning had been fantastic, breathtaking. Marie and I fucked so hard that I was actually afraid I would die of pleasure from her bouncing relentlessly on my cock for a half an hour. When I came, I actually saw stars. After Marie jumped off me without so much as a peck on the cheek and ran into the kitchen to start breakfast, I swore to check the internet to see how often people died of heart attacks during sex. I felt my pulse, which was finally starting to go down after a fucking session so intense it seemed it could only end in orgasmic death. I might be a candidate for the emergency ward.
That night Krissy upped the ante again. She appeared in the doorway only a few moments after her mother settled in for her nightly cum feeding.
No chair this time. She had turned up the volume on the music in her bedroom and left the door open, so the sound of long guitar solos reverberated through the hallway. Dressed in a tight t-shirt and panties, Krissy began to dance.
Marie was in the zone, rubbing my cock all over her big tits and her neck and face, giving my cock little Eskimo kisses with her nose and basking in the smell of my manhood. "Daddy," she whined, like a little girl asking for a toy, "Will you paint your little girl's mouth tonight? Will you please fill my mouth with Daddy cock? Please, Daddy?" Then without warning she plunged her mouth down all the way to the root, deepthroating me and fucking her face with my cock.
Krissy went wide-eyed at her mother's cocksucking skills, but didn't miss a beat. Every time a big guitar riff came on, Krissy played air guitar. Her left arm rose in the air at an angle, while her right arm went down towards her panties, wiggling like she was picking the strings frantically. Her hips thrust forward and her big tits, unrestrained by any bra, bounced under her t-shirt. Marie continued to deepthroat me, all the way to my pubic hair, then back up to the very tip of my head, then again all the way down, over and over, barely catching her breath each time as she bobbed her head up and down in time with the music. "I love you, babygirl," I gasped, gripping Marie's hair while looking Krissy in the eye.
When I finally came, it happened on the upswing of one of Marie's deepthroat plunges, with the result that I sprayed her face with cum. Marie just giggled and started scooping the sperm with her fingers, sliding it into her mouth. "Daddy made a mess!" she giggled. I looked over to the doorway and Krissy was gone again.
The next day I skipped lunch and instead took a long walk during my lunch hour. Sexy as this was, I told myself, it had to stop. The fact was, I loved Marie with all my heart. Mindblowing sex and mouth-watering body aside, I enjoyed her company, her intelligence, her wit, her loyalty. Even if she weren't my wife, I'd still want her for my best friend. Was I so stupid that I was willing to endanger that for the sake of her (equally sexy) daughter?
Besides, I had the strong sense that as sexy as Krissy was acting, it was only that: an act. It wasn't that I believed Krissy was a naive virgin who didn't realize the effect she had on men and on me in particular. No, she clearly knew exactly what she was doing. But I couldn't believe that she would ever go behind her mother's back and actually have sex with her mom's husband. That sort of thing may happen in porno flicks, but beneath that extraordinarily fuckable little body, Krissy was a real person who really loved her mother. There was something in her eyes and in that ironic smirk that made me sure Krissy would push away any physical advances from me, even if she had encouraged them in the first place. And then my marriage would go down the drain. Yeah, she was sexy as hell, but I would have to be a disloyal fool to act on Krissy's sexy come-ons.
That night I asked Marie to clear the table by herself so that I could have a talk with Krissy about her schoolwork. Actually, Krissy was doing fine with school, but it was the best excuse I could think of to get her alone.
"So what did you want to talk about, Danny?" she asked.
