Richard told Jack he wanted him to fuck Fiona and she got on all fours and Richard guided Jack's cock through her swollen lips into her wet pussy, they both moaned as he filled her up with hard cock, he watched them for a few minutes Fiona's pussy being pounded and her moans getting louder, he rubbed her pussy and ran the tips of his fingers over her clit changing the pressure from hard to soft getting her wetness on his finger and then massaging it around her arse guiding Jacks cock into it, positioning himself to slide his cock in her pussy feeling Jacks big length inside her, she let out a long moan and told them she felt so good being filled up with two cocks, Richard held Jacks waist as they thrust into her getting faster, Richard felt Jack stiffen and felt his cock harden even more inside and knew he was going to cum, it made him want to cum too and he ordered Fiona to let go and heard her squeal as he shot his hot load into her as he felt Jack squirt and moan with pleasure in her arse.
As they pulled out he watched their cum drip from her holes, Fiona took Richards's cock in her mouth to clean him up and invited Jack to finish off the job which he greedily did, eagerly tasting them both, before they collapsed in a heap, Fiona between them.
Staring at the clear sky watching the stars they lay contentedly, Jack and Richard stroking Fiona breasts and body and occasionally sliding their fingers into her wetness, after awhile they took it in turns massaging Fiona's clit and as her breaths deepened they quickened their strokes and Fiona moaned, making their cocks get harder, Richard kneeled between her legs and started to eat her pussy as she grabbed his hair and pulled him into her so his tongue could get deeper, as he heard her moans get louder he felt Jack massage his balls and run his finger lightly around his hole, making him moan into Fiona's pussy, he motioned for Jack to take his place and told him to fuck her hard watching his thick cock thrust into her while she arched her back to take him in as deep as possible, he could see they wouldn't last long and wanted them to all come together so he kneeled between Fiona legs and slid his cock into Jacks arse, it gripped him tightly, Jack gasped and paused for a second but then smiled and pushed himself back taking in all Richards cock before they rhythmically all moved together getting faster till Richard cock exploded into Jack's tight virgin arse, Jack moaned fuck with pleasure and thrust hard into Fiona as she screamed as her pussy came all over his cock contracting his squirting cum into her.
They all collapsed again and slowly their breathing eased and Richard poured them all more champagne, Jack giggled how he'd thought his stress would be relieved this week by the expansive lakes and rugged hills and not by a horny couple with who he'd shared his first bi experience with, as they lay touching each other, Jack sometimes reaching over and stroking Richards body enthralled at the freedom to touch another man and then trialing his fingers over Fiona's they all fell asleep.
Fiona slowly opened her eyes as the hazy sunlight had started to rise over the hills, smiling as she remembered in turn straddling Richard and Jack through the night riding them in reverse cowgirl so the other could watch their cocks fucking her wet cum filled pussy in the moonlight.
She watched Richard and Jack kissing as she raised herself on her elbow taking in the sight of them stroking each other cocks, Jack slowly moved his mouth down to Richards's cock and Richard moaned and gripped his hair so he could fully take it in his mouth, Jack sucked and licked the top and then used his hand to help bring Richard to orgasm as Fiona watched on rubbing her clit and softly moaning alerting them that she was awake. Richard turned and kept her gaze as he came hard into Jack's mouth briefly glancing down to watch him swallow his load, Jack now still very hard leaned in to hear something Richard had said and they both walked towards her. Taking her to a nearby log, Jack bent her over and pushed into her and then pulled nearly out so Richard could see his young thick hard cock in her pussy she moaned louder and louder till she looked at Richard and asked if she could cum, he nodded and she stiffened into an all-consuming orgasm as Jack pulled out and squirted all over her arse and back. They laughingly exchanged mornings and Richard led Fiona to a brook where he and Jack had washed earlier, they winced as they entered the cold water, and after washing each other's bodies, they returned to the camp. Jack had gone, just a dot in the distance, they ate breakfast and hand in hand followed him down the mountainside sore and satisfied.
