I awoke at dawn. Stacy had left the skylight open, so the scent of fresh, cool morning air filled the room. I lay on my side and watched her sleep as the sunlight gradually illuminated her beautiful face, so lovely and so much at peace. I only wished I had felt the same way.
The enormous implications of what we had done the night before were just beginning to sink in. Not only had I made love to my sister and broken every societal law I thought I believed in, I was not her first incestuous lover. A chilling thought: was I even the second? What do we do now? Do we pretend it never happened and carry the memory to our graves? Do we have an affair? If so, how? What if one of us meets someone else?
But weighed against all the uncertainty was this: it was the most amazing, electric sex I had ever had in my life. If at all possible, I wanted more.
I knew Mom would sleep in, so I donned my robe, tiptoed to the bathroom, cleaned up, and returned to my sister, who was just beginning to stir. Seeing me in the doorway, she smiled mischievously and patted the sheet next to her. Already erect, I hung my robe over a chair and snuggled up next to her.
"Kiss me, Charles."
Stacy's lips were smooth and delectable, and she trailed delicate fingers along my cock, ardent and ready. But she excused herself to freshen up, leaving me to stare at the ceiling and torment myself by not touching my turgid tool before she returned and snuggled up next to me. She lay on her side and gently stroked my cock.
"Do you still love me?" she asked. "Do you feel all right about what we did last night?"
"I love you," I replied, "and I don't know how to feel about what we did last night."
"Seems to me you do," she replied, giving me a playful squeeze.
"What are you doing?" I asked.
Stacy held my dick so it was poking straight into the air. Her lips parted and took in my cockhead. I cried out, but she silenced me with her free hand. Transfixed, I watched as my sexy sister's head slid slowly down my shaft, stopping halfway down. I nearly swooned.
Looking up for a second, she said, "I'm sorry, that's as far as I can take it."
"It's okay! Just--"
Flashing me a grin, she resumed, coordinating her lips, tongue and left hand to work my dick, while with her right teasing and caressing my tight and bloated balls. I could no longer lie still. I started to move my hips, trying to time my thrusts with Stacy's siphoning mouth. I reached out and tweaked Stacy's nipple so that I could return at least a little bit of the pleasure she was giving me.
"Mmmmmhh!" she replied. Lifting her head, she exclaimed, "Oh, I can't stand it!" and climbed on top, stuffed my cock into her drooling snatch, and then sank all the way down, her expression, as well as mine I'm sure, pure erotic bliss.
Stacy leaned forward now, our eyes locking. As we moved together, I gathered her smallish tits in my hands and pushed them together so that the nipples bulged. I nibbled and licked as Stacy moaned and writhed atop my pile driver prick. When I placed my thumb on her clit she went off; I picked that moment to do the same. We mashed our mouths together as I filled her with thick, syrupy gobs of sperm.
As we slowed down, I could feel rivulets of our mingled juices running from her into my pubic hair. We looked at each other and started to giggle.
"Well, I guess we can talk now," she said at last, nestling in my arms.
"I think we're lovers."
"Uh-huh."
"Was it like this for you and Dad?"
"Not quite like this. He was so much older. He took his time. I liked that."
"You seemed pretty enthusiastic about this."
"I wasn't expecting this, Charles. I'm on as uncertain ground as you."
"You've had some experience with this, though. Did Mom know?"
"I don't think so."
"How did you keep it from her?"
"Oh, that was easy. You know she works 8:30 to 4:30 editing the entertainment section for the Eagle. Dad sold real estate. We only had to wait until she was out of the house."
"That was it? You never took a chance while she was here?"
"Sure we did. That was some of the best. One time when Mom was washing dishes I blew Dad on the living room sofa while he was watching the news. He was furious, but he didn't stop me. I had him licked clean and zipped up just about the time Mom finished drying the dishes."
"You never felt bad about it? Did you ever try to break it off?"
"You want to hear every sordid detail, don't you, Charles?"
I did; I was half erect again already. "How did it start?" I asked.

The thing with Dad started about four years ago, when I was a freshman in college. You'd already moved to the city by then. Like you, I had no choice but to go to the state school because I could save a fortune on room and board living here.
