It's Amy.

Amy came walking up the trail, arms held out as she took in the whole scene. Elizabeth covered her mouth with her hands and started to giggle, still on her knees in front of my drooping cock. Meanwhile, Corrine tried to take a step away to hide what we were still doing, only to clutch me tighter as I redoubled my efforts with my fingers.

Amy was shaking her head with a playful scowl as she reached us, hands on her hips. "I take off running another half mile down the trail, and here all of you are getting frisky."

"Sorry," Elizabeth chuckled.

Amy smiled down at her. "Look at you go, girl! Looks like you showed him a good time." She then looked up at Corrine, whose head was still in my shoulder. "How about you, Corrine? Enjoying yourself?"

"Mmm-hmm..." she moaned softly in reply.

Amy's gaze fell to my still-exposed manhood, a small smile creeping across her lips. "I'm feeling a little left out right now. I don't suppose you would mind if I followed your lead, Elizabeth?"

"You're welcome to try," Elizabeth replied, as she stood up, putting her sweatshirt back on. "But he seemed pretty spent."

Amy merely bit her lip with a smile as she tied her hair back in a ponytail. "I accept your challenge. Don't forget...I'm pretty good at this sort of thing." She walked right up to me, brimming with confidence as she gently cupped my balls in her hand. "Oh yeah. This won' take long." She glanced over at Corrine and winked before saying, "Want him to keep going?"

Corrine only moaned softly in reply, nodding her head as she clutched me tightly.

An almost sympathetic look crossed Amy's face as she brushed blonde tresses from Corrine's forehead, knowing full well the bliss that sat of the edge of orgasmic delight. When her eyes met mine, however, there was no sympathy at all. Only a message:

Buckle up, Stud.
