My stepdaughter Kelsi had just turned 18 a few weeks ago. I married her mom, Laura, when Kelsi was 13. I watched Kelsi develop into a beautiful young woman, with the same petite build as her mother. She was slightly taller than her mom's 5'6" stature, and her chest was slightly smaller than her mom's C-cup, with a nice firm ass.
"Hey John, any idea when my mom will be home?" Kelsi asked, peeking her head into my home office door.
"Not until this evening sometime," I replied, smiling at her.
"Oh," She said, looking down at the floor. "Well, can I come in and talk to you?"
"I guess so. What's up?" I asked, watching her enter the room and close the door behind her.
Kelsi sat down on the loveseat across the room from me, smiling. "Can you come sit by me?"
I got up from my chair and walked over to the loveseat, sitting down next to her. "So what's up?"
"Do you think I'm attractive?" She asked bluntly.
"I'm sorry, what?" I blurted out in shock.
"You know, do you find me attractive, good-looking?" Kelsi asked again but with more emphasis.
"I... I don't think I can answer that," I responded, completely caught off guard with her question.
"Why not?" She asked, looking at me quizzically.
"Well, because you're my stepdaughter," I said, looking for her reaction.
"I know you're my stepdad, but that shouldn't matter if you find me attractive," She said sternly.
"I shouldn't be answering questions like that from you," I said.
"I know, but it just seems like I'm not attractive to boys. So I figured I'd ask a man like you," She said, biting her lower lip.
"Well it's still highly inappropriate," I said, looking at her sincerely.
"Come on John, can't you just tell me if you find me attractive or not?" She pleaded, laying a hand on my thigh.
I looked down at her hand, then up at her. "You sure are persistent, huh? If you must know, I do think you are attractive," I answered, hoping that would be the end of it.
"You do, huh?" Kelsi's face lit up, her hand lightly massaging my thigh.
"Yes, I think you're very attractive. I don't know why you think boys your age don't find you attractive," I said, looking back down at her hand on my leg.
"It might be because I find myself being more attracted to men," Kelsi smiled, her hand rubbing closer and closer to my crotch.
"Men?" I questioned, shifting myself on the loveseat. Trying to move my crotch away from her hand.
"Yeah, guys that are much older than me. Men like you," She smiled, her hand lightly squeezing my thigh.
"Yo... you are still young, you have plenty of time to find a guy closer to your age," I said, clearing my throat nervously.
"I know John. But I just find guys my age to be immature," She said, moving her hand to my inner thigh.
"I... I ca... can see that. I... I know I was at that age," I said, my cock beginning to tingle.
"So you understand what I'm talking about," Kelsi smiled, laying her head on my shoulder.
"Wh... what are you doing?" I asked, looking down at her hand moving up alongside my covered cock, on my inner thigh.
"Just relaxing and enjoying your company John," She said, looking up at my eyes.
I grabbed her hand on my inner thigh and pulled it away. "That is not appropriate, or relaxing," I said sternly.
"But John, you said you found me attractive," She smiled innocently, pulling her hand away from mine.
"Yes, after you kept pestering me about it," I said, looking at her angrily.
"And I find you attractive, very attractive," She smiled, grabbing the button on my pants and quickly unbuttoning them.
"Kelsi, stop. This is wrong," I protested, feeling her reach into my underwear and pull my limp member out of the top of them before I could react.
"What's so wrong about it? You're a guy and I'm a girl," She smiled, lightly tugging on my limp cock.
"I'm also your dad," I said, my cock beginning to grow in her hand.
"Step... Dad. And it seems that you like me touching you," She cooed, looking down at my quickly hardening cock.
"We can't do this," I continued to protest, but starting to enjoy the attention.
"Are you going to stop me? Mmm, I bet my mom is really happy with this dick. It's so long and thick," She smiled, moving her hand a little faster.
I looked down at her hand tugging on my cock. "Kelsi stop this right now," I said sternly.
Kelsi stopped her hand at the head of my cock, and rubbed her thumb over the tip of it. "Mmm, somebody's leaking already. Are you sure you want me to stop?" She moaned, before sliding her hand back down my cock.
"Fuck," I hissed, feeling my balls churning already.
Kelsi started rapidly tugging on my cock. "How about this?" She giggled.
"Oh God," I groaned, moving my hips in time with her hand.
"What's wrong, John," Kelsi cooed, stroking the glans of my cock with her hand.
My body started to jump and tremble as she continued to tease my sensitive head. "Just make me cum," I groaned, lifting my hips, trying to get her to move her hand back down.
"But I thought you wanted me to stop," Kelsi laughed, slowly moving her hand down the shaft of my cock.
"Ahhh," I gasped, feeling relief when her hand moved away from my sensitive glans.
Kelsi focused her attention on my cock, moaning as she stroked up and down. "Are you going to cum, John?" She cooed, going back to teasing just the head again.
"Ye... yes. Oh God," I groaned, my whole body convulsing now.
"Somebody's sensitive, and leaking badly," Kelsi laughed, rubbing her thumb over the slit of my leaking member.
"Pl... please just stroke it," I gasped, feeling my load boiling in my balls.
"But what if I stop?" Kelsi said playfully, moving her hand completely away from my 7" erection.
I looked at her pleadingly, "Pl... please quit teasing."
"But didn't you want me to stop," Kelsi laughed, grabbing my cock again and started stroking it.
"Mmf, mmf," I growled, biting my tongue to keep from yelling out in pleasure.
"Cum for me, John. Cum for your stepdaughter," Kelsi cooed, moving her hand as fast as she could.
"Fffffffuck," I yelled, throwing my head back and feeling the cum rushing up my cock.
"Yes," Kelsi exclaimed, stopping her hand at the base of my cock.
Cum flew out of my cock, into the air, and landed on my shirt. "God, fuck," I gasped, my cock throbbing hard each time it shot more cum out.
"Mmm, look at all that cum. God that's so hot," Kelsi cooed, slowly moving her hand up my cock.
I lay there, breathing heavily. My cock was still oozing out cum as it twitched in Kelsi's hand and ran down my shaft. "God that was good," I gasped, lifting my head to look at my stepdaughter.
"You made quite the mess on your shirt, and on my hand," Kelsi giggled, letting go of my deflating cock and showing me the cum on her hand.
I looked down at the mess on my shirt. My cock lay limply on my lower abdomen, still glistening with my drying cum. "Yeah I did," I smiled, finally catching my breath.
"Hmm?" Kelsi moaned, bringing her cum covered fingers to her mouth and licking them off. "Tasty," she smiled.
I smiled at her, "But this can't happen again."
"Why can't it? Don't you feel good now?" She asked, running her fingers across my limp cock.
"Yes, but it was wrong," I said, jumping as she rubbed my sensitive head.
"I gave you the chance to stop me, but you told me to keep going. So apparently, you wanted it, too. Is my mom not taking care of you?" Kelsi smiled.
"What? Kelsi, your mom is very good to me if you must know," I exclaimed in shock.
"Well by the looks of it, I can take care of you too," She said, beginning to move off the loveseat. "Maybe next time I'll get to feel that thing inside of me," She whispered, before backing away.
"Absolutely not," I grumbled, glaring at her and buttoning my pants.
-------------------------------------------------
A week after Kelsi had given me the handjob. Laura got a request from her boss to fly out to the East Coast for a couple of days. A coworker was sick and wouldn't be able to attend, leaving my wife, the only other person that could go.
While I wasn't thrilled about her going, I knew she wanted to go. "You'll be fine for two days without me," She kept saying before she headed out.
I was relaxing on the couch in the front room when Kelsi walked up behind it. "So we are all by ourselves for two whole days," She giggled, looking down at me.
"I know Kelsi," I grumbled, remaining focused on the TV.
"So what are we going to do with our freedom?" Kelsi implored.
"Nothing," I said.
"Nothing? What's the fun in that?" Kelsi asked playfully.
"Who said anything about fun?" I countered.
"Oh come on, John, why are you so grumpy?" She asked, walking around the couch in front of me.
"Don't get any...," I trailed off, finally looking up at her, shocked by the sight in front of me.
