This is part four of my long-neglected story, "Dad, I Have a Question." It isn't absolutely necessary to read the earlier chapters to understand this one, but, like I said before, it can't hurt.
PLEASE NOTE: This is part of a completely fictional series about a single father, his daughter, and her friends. No actual virgins were harmed in the making of this story.
Brief synopsis of events so far: Jamie, teenage daughter of single parent Bill, asked him a question about sex. One thing led to another. When this chapter begins, Bill and his daughter have been having wild and satisfying sex almost daily for a few weeks. Jamie's best friend, Kiersten, who is spending the weekend at Bill and Jamie's house, has discovered their incestuous relationship.
**********
"Daddy Bill," Kiersten said, her gaze flickering from my eyes to my swollen manhood, "I need you to teach me stuff."
The last shred of my morality was gone. "Let's go to my room," I said.
Jamie led the way, naked Kiersten was next, and my cock followed behind them. When my daughter walked into my room, she turned on the light and took off her shirt. Two beautiful young women were naked in front of me.
My cock bobbed in rhythm with my pulse. "Kiersten,..." I began.
She stepped to me and pulled off my robe. Then she unsnapped the waistband of my pajama pants, letting them fall around my feet. "I want you to teach me everything you taught your daughter. Please."
"Do you know what you're asking, Kiersten? I've masturbated Jamie to orgasm, and she's done the same for me. We've had oral sex, and I've cum in her mouth. I've taken her virginity. I've ejaculated inside her. Is this really what you want?"
Kiersten moved against me, forcing my cock to slide up along her abdomen. Her large breasts pressed against me, the nipples firm on my chest. She put her arms around my neck. Just before she kissed me, she said, "Yes."
"I had never done any of this stuff," Jamie said, watching her best friend's tongue play with mine.
"I haven't done much," Kiersten admitted when we paused for air. "I've kissed before, and I let a guy feel me up once, but I was afraid to do anything else."
"Didn't you like it?" Jamie asked.
"Not as much as I thought I should," Kiersten said, moving slightly to grind my cock on her belly. "He was kinda rough. I don't think he knew what he was doing."
"Dad does."
"I always thought an older guy should be my first. Bill, what should I do?"
"Nothing you're not comfortable with," I answered.
"You should be comfortable enough to play with his cock," Jamie said. "You did that before."
"He was asleep."
"No he wasn't," Jamie giggled. "Were you Dad?"
"No."
Kiersten blushed visibly. "You knew I was touching you?"
"Yeah."
"Oh.... Should I do that again?"
"Why don't we lie down so we can touch each other?"
Jamie took my hand and led me to my bed. She had me lie on my back in the middle, and she got on her knees next to me. "Come here, Kiersten."
She knelt opposite my daughter, her legs slightly spread. There was moisture on her bare slit. She put her hand on my hard penis and stroked it timidly, just like before.
"Watch," Jamie said, pushing her friend's hand away. She fondled my manhood, the way she had when this all started. Stroking me gently but firmly with one hand, she lightly caressed my glans with the fingers of her other. "Dad says it feels real good when you run a finger around this ridge here. See this little triangle thingy?" she asked, bending my cock up toward my belly. "Dad likes it when you tickle that. You try it."
Kiersten replaced Jamie's hands with her own, imitating the motions she had been shown.
"Does that feel good, Dad?" Jamie asked.
"Uh huh."
"Lie down next to him, Kiersten. Let him make you feel good, too."
When I first held Kiersten's round breast in my hand, I stopped worrying about the consequences of what we were doing. Until I had touched Jamie that way, I had forgotten how amazing a teenage boob feels, how warm, how soft but firm at the same time, and how arousing. Kiersten's nipple was as hard in my hand as my cock was in hers.
She knew how to kiss. Every time I switched from fondling one sumptuous breast to the other, she moaned as we crushed our mouths together.
"Has anyone ever sucked your nipples?" I asked.
"Just me."
"Would you like me to show you how I do it?"
"I'm so turned on already," she whimpered. "Yes, please."
I pushed her hair aside and whispered into her ear, "Sweetheart, I'll do everything I can to make you feel good. If you like something, tell me. If something makes you uncomfortable, I'll stop." I inched my hand down from her breast and across her belly. She gasped when I ran my fingers over her mound, enjoying her soft skin. I didn't go any lower. It wasn't time for that yet. I trailed kisses from behind her ear and onto her throat. She arched her neck, and my tongue found the hollow below her larynx and began to play.
"Oh, God," she hissed.
I massaged her puffy mound just hard enough to pull at the tender skin around her clit. My kisses went lower, into her cleavage. By this time, her nipples were straining for the ceiling, begging to be sucked. When I licked one, she jolted slightly, and I smelled fresh, hot pussy.
"You're making me wet," she whimpered.
"Really?" I hardened my tongue, and flicked her proud nipple back and forth.
Jamie moved on the bed so she was lying across our legs. I could feel her warm breath on the hair on my thighs. She giggled softly. "Kiersten, that's making my dad drip pre-cum."
"What's pre-cum?" Kiersten gasped as I devoured her lovely breasts.
"This." Jamie crawled over to Kiersten's side of the bed and took her friend's hand in her own. She rubbed the head of my dick with the girl's finger, and then raised it to Kiersten's mouth. "Taste it. Feel it on your tongue."
"Is that what his cock tastes like?"
"Kinda," Jamie answered. "I like it. I like giving and getting oral sex, at least with him. Dad, why don't you lick her now?"
"Good idea." I moved down and placed a small kiss on Kiersten's warm mound where my fingers had been.
She was already trembling before my tongue first touched her. Her smooth pink skin was shiny with leaked fluids. She smelled sweet and hot, a little different from Jamie, but still pure, fresh, and ripe. I meant to start slowly, nuzzling her with my nose, kissing her thighs and her lips, trailing my tongue softly over all her exposed goodness before plunging it into her little hole, but I couldn't help myself. I had to taste her.
