"Fuck," Jeff wheezed, "I'm so out of shape." He trudged up the trail, giant Sequoias all around him, the air moist and thick with the aroma of pine needles.
"Come on, you can do it. One foot in front of the other," Sara encouraged, her plump, round ass bouncing back and forth in her tight black athletic pants.
"I swear, that ass is the only thing that keeps me going."
"Yeah? This ass?" she asked, looking back flirtatiously, giving herself a quick smack. He watched as her ass jiggled, slowly settling back into place. He walked up to her slowly, hands outstretched, reaching out for her. At the last second, she spun around and grabbed him by the wrists. She looked at him with a devilish gleam in her eyes. "Uh uh uh, not yet. Let's finish up this hike and you can claim this as your prize when we get home." She brought her mouth right up to his ear and whispered, "I want to feel your cum all over my ass." He felt a jolt run through his entire body, settling in his groin. She gave his ear lobe a quick nibble, turned around, and hiked onward. He followed behind, reinvigorated.
They hiked on in silence, enjoying the sights and sounds and smells of the forest. Jeff felt small, but in a good way, an appreciative way. These ancient, giant, beautiful organisms. How wonderful, he thought, to be able to walk amongst them. And how wonderful to share this moment with the love of his life.
"Hey," Sara said, jostling him out of his moment of existential clarity. "I really have to pee."
Jeff chuckled. "Okay, I'll stand guard."
Sara scampered off the trail into the forest, looking for a safe place. She found a massive burned out tree trunk, protected on three sides. Perfect, she thought. She snuck inside, and just as she had pulled her pants down over her ass, she heard what she thought was a muffled moan. She quickly pulled her pants up, startled. She stood still, listening intently, and she heard it again. "That's definitely a person," she thought. As she listened, it became clear to her. "Holy shit," she thought, "someone is fucking in the woods." She crept out of her hollowed out tree, and began following the moans, tip-toeing as softly as she could, avoiding any fallen twigs and dried up leaves. The moans got progressively louder as she went on, and finally she saw them. A woman was bent over an enormous fallen log, hands braced on the wood, pants pulled down to her ankles, back sharply arched. A man was standing behind, pants just below his ass, one hand firmly grasping her hip, and the other over her mouth, muffling her moans.
Sara stood there transfixed, watching as the man fucked the woman deeply, listening to the rhythmic "thwap, thwap, thwap," of his thrusts and the sounds of pure ecstasy coming from her covered mouth. Sara gazed as his ass clenched and relaxed with each thrust, as the woman squirmed in delight. He pulled his cock out, glistening with her juices, and reached down to her breasts, pulling her up to him. He kissed her neck softly as he caressed her breasts through her t-shirt. He spun her around, and at that moment, Sara tucked her head back behind the tree to avoid being seen. She peeked out from the tree slowly, and the couple was kissing deeply, passionately. He broke the kiss, and pushed her gently downward. She kneeled down, taking his wet cock deep into her mouth, slowly. "Okay," Sara thought, feeling herself starting to get wet, "I have to go tell Jeff!"
She tip-toed back the way she came, and when she finally got back to the trail, he asked "What took so long?"
"There is a couple fucking in the woods!"
"What?"
"I stumbled upon a couple having sex."
"Did they see you?"
"I don't think so. They were still at it when I headed back."
"Wow. Okay..."
"So... would you like to go watch them with me?"
He was a bit taken aback. He never knew she had any interest in voyeurism. "Yeah," he sputtered out. "Sure!"
"Okay, wait, I didn't actually pee. Give me a sec." She went off in the opposite direction, and feeling more urgency settled for the nearest tree.
