I woke up suddenly. It was dark and I was a little disoriented. The window was on the wrong side of the bed. It took me a second to figure out that I was in Amy's bed. I squinted to look at my watch. It was 4:20 AM. I looked to the other side of the bed and Amy was sound asleep.
I quietly got out of bed, tiptoed into the adjoining bathroom, and slid the door closed. I used the toilet and then washed my face. Turning off the light and slipping out the opposite door to my own room, I climbed into bed and relived the whole night from beginning to end.
It was after midnight when I went into my sister's room and crawled under the sheets next to her. She had already fallen asleep but woke up when I put my arm over her and held her tit in my hand, gently squeezing her nipple, and she felt my hard cock pressing into the crack of her ass.
"What a nice way to be woken up," she said. "You didn't let me finish this afternoon," and she rolled over and pushed me to my back. Then she crawled down under the sheets and took my cock in her mouth, cradling my balls in her hand. I threw the sheets off because I wanted to see my sister's lips around my cock.
She looked up at me and smiled. I still was having a hard time believing that my sister was the best lover I have ever had. OK granted I am only 18 and haven't had a lot of lovers but you get the idea.
She took her time sucking me. Her tongue stroking the underside where it is the most sensitive. She squeezed my balls gently. It was obvious to me that she was an experienced cock sucker because she knew how to drive me crazy without making me cum right away.
"These balls are huge and heavy. They must be very full. I want it all Tommy. I want it all in my mouth. Will give it to me? Will you fuck your big sister's mouth and cum for me?" And with that, she took the whole thing in her mouth again. Her head then started moving faster. Tilting her head a little from side to side, pushing against her cheek, softly scraping her teeth against the head. She was driving me crazy. Then her fingers started stroking my shaft.
She looked at me and in a little girl whiny voice said, "Give me your cum, Tommy. Please give it to me." And took me back into her mouth and kept stroking.
Well, it only took a few minutes and I felt the tingle in my balls. I started thrusting my hips up, driving my cock into her mouth. She knew it was coming and started making an urgent moan almost begging for it, all the while never breaking eye contact.
I stiffened and my cock started pulsating, pumping warm cum into my sister's waiting mouth. We both stopped moving while I shot stream after stream into her mouth. She had a dreamy, happy look in her eyes. I heard her gulp. Once. Twice. I had pumped a lot of cum into her mouth.
She kept my cock in her mouth even as it started to soften. She wanted those last big drops. Then she released me but licked the drops as they appeared. When she was sure she had it all, she kissed the head. I thought, "Wow, Hal did that once and I thought it was weird. When Amy does it I want more."
Amy crawled up next to me and we kissed. It was a deep kiss that I will never forget. I could taste my cum in her mouth. She laid her head on my shoulder, her naked body against me.
"I love you, Tommy," she said. She has said those words before, but something in the way she said it tonight sounded different.
"I love you too, Amy," I said, as she started tracing circles around my nipple with her finger. Soon she stopped and I realized she had dozed off. I allowed myself to do the same. I didn't think I could do much more right now anyway as I was exhausted.
And that's when I woke up at 4:20 AM. After getting into my bed, I dozed fitfully the rest of the night and finally around 7:30 I got up and went into the bathroom.
Looking into Amy's room I could see she was still asleep. I slid the door closed and got in the shower, then dressed, ate some breakfast, and was off.
It was a slow day again, being Sunday, but I was still pretty tired by the time I got home.
I had gotten home from work at 4:30 PM and no one was home. Went up to my room and found a note on my bed.
"My dearest Tommy,
