The next morning I awakened – still naked – in Amy's sleeping bag to find that she had gone. My mind drifted back to the events of the pervious night and my cock hardened instantly. I remembered fucking her tits and coming all over her face and watching her lick the come from her fingertips. I couldn't believe I'd gotten so lucky, having a friend like Amy.
I got up and stretched, enjoying the warm morning sunlight on my naked body. Wondering where Amy had gone to, I called out, "Amy? Where are you?"
I heard her voice coming from the direction of the hot spring we'd bathed in the night before, saying, "This way, sweetie!" I happily followed the sound of her voice and found her waiting for me in the same hot spring. She was sitting against the edge of the warm pool totally nude, her D-cup tits mostly exposed above the water line, her nipples hard and erect.
"Come on in," she said, grinning at me.
My cock sprang to attention at the sight of her as I waded in. I walked closer to her and my cock bobbed in the air just inches from her face right as I was about to sit down next to her. She stopped me with a gesture and grinned up at me, her glistening perfect lips just inches from the head of my cock. "Before you sit down," she said casually, as if there was nothing unusual about her request, "I want you to fuck my mouth."
My eyes rolled back in my head as I grinned and said, "Yes, ma'am." Without another word, I slid my cock between her welcoming lips and started thrusting back and forth in and out of her mouth. I could feel her warm tongue pressing firmly against the bottom of my shaft, swirling around the head, working it up and down as I slid in and out, faster and faster. I felt her small, perfect hands cupping my ass gently and urging me forward, urging me to thrust deeper and faster. I happily obliged, thrusting forward as hard as I could. She took every inch of me into her throat and never gagged once.
It wasn't long before I knew I was going to come, and I told her so between moans. In response, she simply thrust her head forward, impaling her mouth on my cock and taking it in all the way to the root. Her lips were sealed tightly around the base of my cock, and her eyes turned upwards, gazing deep into mine. At this moment, I started coming harder than I ever had in my life, spraying it deep inside her throat. My entire body shook violently, and she just sat there, locking eyes with me and milking my cock with the muscles of her throat.
After a moment, she slid free, stopping to suck and lick the head clean (which gave me a little involuntary shiver), and relaxed against the edge of the pool. I collapsed next to her with a splash, gasping for air and wrapping my arms around her. I kissed, licked and sucked her lips, making out with her ravenously, thanking her between kisses for what she'd just done.
She said, "Anytime, sweetie," making me grin wickedly at the prospect of fucking her mouth anytime I wanted to.
