My little sister, Annie had come back from College a changed girl. Sure, she looked and dressed the same. But the day she got back from her freshman year, it became clear that she wasn't the innocent sister that had left in fall.
How could I tell?
I'd been home for a couple days on Summer Break, when she got home too.
Her first night home I heard her tiptoe silently into my room. I felt the covers being drawn back. Then I felt her lips on my cock, engulfing it in her hungry mouth. I was instantly hard, barely able to see her outline in the dark, I just closed my eyes while she went to work on me. Annie knew what she was doing, and it didn't take her long before I shot a huge load of spunk in her mouth. She eagerly swallowed it down, and then just as silently, she was gone.
The next morning she acted as she always had. My little sister. Goofing around the house. Sunning herself by the pool out back. But that night, around midnight, she was back under my sheets, draining another jizz cocktail from my balls.
Now my sister is very cute. At 19 years old, not a beauty queen, but more like a freckle faced athletic girl next door type with long sandy hair, reddish highlights, pale green eyes and pert B cup breasts. She'd been a pretty straight arrow in high school, so her nocturnal behavior now had me a little puzzled.
After Mom and Dad had left for work. I was determined to get to the bottom of it, so to speak. I caught her out by the pool.
"What gives, Sis?" I began.
"What do you mean, Augie?" She countered.
"I mean the blowjobs you been giving me since you got home." I threw out.
"Oh. That." She replied. "Are you complaining?"
"God no, Sis! You're an amazing cocksucker. I just wanted to know where it was coming from." I said.
"I like jizz, Augie. I just love the way it tastes, and how it shoots into my mouth. It's just... yummy." She explained, shrugging her shoulders. "I just figured I'd see if I could get some from you. I didn't think you'd mind too much. You don't mind...do you?"
She went on to tell me that she'd gotten picked up at a frat party about halfway through the first semester. The guy was kinda cute, and one thing had led to another, they'd gone back to his room, and he'd whipped it out. She sucked him off and that was that. She'd wanted more. The guy was on the football team, and word had quickly gotten around in the locker room. So, within just a few days, she had a steady supply of hunky cocks to suck on, and so she availed herself of every opportunity.
"So, you're promiscuous, then." I concluded.
"Don't be silly! No! I just suck cocks. That's it." She answered, obviously offended. "Everyone knows it's my thing..."
"You've never..." I left the rest hanging.
"Oh, I've made out a few times and gotten felt up once or twice, but I've always been very clear about what I was after. A mouthful of sperm." She said plainly. "So far, nobody's had a problem with that."
"But hasn't it made you curious... about... other stuff?" I asked.
"Sure. But so far, I've loved this so much. It makes me feel... empowered. I can control a guy's body to get what I want from it. For now, I guess that has just been enough." She answered, adding. "Hey, Mom and Dad are gone do you want me to..."
Annie had skills, and I guess she really liked my cock. I'd always been a heavy cummer, but with her encouragement I was shooting from the three point line every time, and she soon had me on a regular schedule.
It was after a couple weeks of that, and I had to admit that as much as I enjoyed her attention, it left me feeling just a little guilty. I mean I knew she had a few toys in her nightstand drawer to take care of business, but I really felt that my lack of reciprocation was damned selfish of me. I got it in my head to ask her if I could go down on her. I'd done it a few times to girls I'd picked up, and they had all gotten off in short order so...
"I mean, I'd like to... ya know... give a little something back, Sis." I'd explained when I made my offer.
"I just don't know, Augie... Let me think about it." Had been her reply. At least she hadn't ruled it out completely.
A few days later, after she'd finished me off in the morning. She brought it up.
"Do you still want to... you know..." She stuttered. "I mean is the offer still open? Because, if it is, then... yeah...I think I'd like it if you did..."
So there in my bedroom I found myself arranging my t-shirt clad Sister sideways on my bed and pulling off her shorts and panties. A combination of sucking me off, and anticipation for what I was about to do, had her pussy absolutely drooling. She was cute down there as well. A neatly trimmed thatch of hair topping a lush, prominent mound featuring the most delicious looking pussy lips I'd ever seen. I stared at it for a full minute before proceeding.
Kneeling bedside and wrapping my arms around her thighs I pulled her close to my face. She smelled sweet and aroused. I touched her gently with the tip of my tongue and she sucked in a quick breath. I traced between her pussy lips, tasting her wetness for the first time. She squirmed just a bit and let out a soft moan. I began to go deeper with my tongue licking her from bottom to top and then suckling her clit, which I could feel swelling as her moans became more and more pronounced.
I was taking my time, but even so, within a minute Annie's body shuddered and she let out a long keening groan as I felt her convulse against my face. I let her regroup, and then proceeded to repeat my attentions until I felt her explode once again into my mouth. I was as hard as a rock.
