Karyn made sure to take her cell phone, which had been left on the kitchen counter. We went upstairs to her
room. Her room was at the end of a long hallway so we would know if her sisters broke their promise. She
opened the door to her room and sighed in relief. “At least they didn’t do anything in here,” she said. She
looked around the room and added, “It doesn’t seem like there’s anything different here.”
“Except that your clothes are probably a little different,” I said. She nodded. “By the way, how did you
know what your bro…uh, sisters have been doing?”
“I don’t,” she admitted. “They’re always usually up to something, so I bluffed. Worked, didn’t it?” she
grinned devilishly.
I chuckled. “I would say so. Was Cady hitting on me?” I asked.
“I really don’t know,” Karyn replied. “I can’t really tell. Something inside me tells me that he…shit, SHE,
has. I guess that’s why I got so mad. But look at both of them. They’re changed like you, but they acted
just like they always have.”
I sat down on the bed and Karyn followed suit. “Maybe this change hasn’t affected everyone’s personality,” I
said. “Or maybe it’s an effect of puberty.”
“Something to look forward to with Leah,” she said.
“I don’t relish that thought,” I said. “She’s really such a sweetheart, it’s going to be weird to see her act
like an teenage male.”
“Good thing she has such a great big sister to help her out then,” Karyn teased.
“Good thing I have you to help me,” I said. We both laughed. For the next minute or so I just looked around
her room to see if anything looked different to me. It was mostly as I remembered it. In doing so I
remembered the last time that we were in Karyn’s room together. We were both bored, but feeling a little…
restless, shall we say. Karyn decided that she wanted to give me a blow job and I didn’t resist. Like she
had reminded me earlier, we’d had casual sex a few times, but this was the first time we had done something
other than regular intercourse. It made me feel weird afterward, though Karyn didn’t seem to do the same.
“So,” I said. “You were pretty hot downstairs.”
She looked at me curiously. “What do you mean?”
“Like you were really mad,” I said. “Ready to just hulk out or something.” This is what I said to Karyn, but
my honest feelings were that she was hot in the sexual sense. Tearing into her sisters made me slightly
aroused. I didn’t know why, because it was not something I’d find arousing before my change. Perhaps I was
aroused because it was Karyn.
“So what?” she answered. “They deserved it. If they’d broken anything valuable, I’d never hear the end of
it.”
“What do you mean?” I asked as I inched closer to her.
“Your mother might be different,” she said, “but I just don’t think my parents will be. This isn’t the first
time they’ve just gone on an ‘overnight trip’ like this. They expect me to take charge and if something bad
happens, it’s always my fault because I didn’t keep those two idiots in line.”
I could see that she was getting angry again. This would work to my advantage, I thought. “That sucks,” I
said. I placed my hand on her thigh and patted it gently, in a sympathetic manner.
“You’re lucky you just have Leah for a sister,” Karyn said. “She might be nosy, but that’s the worst thing
about her.”
“Oh, yea,” I agreed. My hand began to move closer and closer to her penis. She still didn’t take notice of
what I was doing. “It’s not fair because you’re not the problem.” My hand reached her penis and I softly
touched it with the back of my hand.
This brought her full attention to me. “Joey, what are you doing?” she asked. I took her penis in my hand
and began to stroke it.
“Returning a favor,” I answered. Then I whispered into her ear, “Just let me do this.” I stroked her penis
harder and the effect was obvious on her face. She moaned softly and closed her eyes. “You’ve got me so
turned on, that I just have to suck your cock.”
“Joey! I’ve never…uh…heard you say that,” she said as my stroking increased in speed.
“I do now,” I said. I slid off the bed but did not release her cock. I wanted to get it nice and hard before
I went down on it. I positioned myself in front of Karyn. She moved a little closer to the edge of the bed.
Once I was satisfied with how hard she was I leaned down and enveloped her cock in my mouth.
Instantly she began to moan much louder. I went up and down on her cock and as I did my head bobbed up and
down slightly. Karyn put her hand on my head and kept it forced down on her. I didn’t mind at all since this
told me she enjoyed it. It also had the effect of making me go faster. Karyn responded by moaning louder and
longer. I kept going as fast as I could. Suddenly I felt her cock buckle and waves of warm liquid shot into
my mouth. Karyn climaxed loudly, let go of my head and fell backward onto her bed. I eagerly swallowed every
bit of her cum. It tasted weird but simultaneously it felt completely natural.
Once I was satisfied that she was done I released her cock from my mouth. Karyn was still down on her bed,
her eyes closed and small beads of sweat covering her body. She continued to moan softly, as if the
experience had overwhelmed her. Suddenly I had another idea.
