Hump her thighs

"Oh, god..." Elisha whispers as she can feel your hard cock pressing up against her rear. She doesn't try to fight you though, but simply brace herself against the cabin wall.

You can't find your mark however, as her position and tightly tied legs makes her very difficult to enter. Instead you just keep sliding your shaft between her thighs and up against the outer lips of her pussy.

At least her flowing juices helps a lot with the friction, making for a pleasant ride for you both. Soon your victim is starting to push back into your hips, once she's realized that you're not about to stick your thing inside of her just yet.

Meanwhile you've both returned to watching the show going on inside of the cabin. By now the two girls are busy eating eachother out again, and the sight is making you pump yourself harder and faster against Elisha's tight buttocks.

Your hands reach around to her front again, making her moan as you knead her tits and then slip down to rub at her clit. She even helps you pulling her top off over her head, giving you full access to her perky nipples.

She's looking a little shocked to find that she's actually getting off on all this, but by then it's far too late to try and control herself.

"Nuh-ugh...!" She grunts into the wall while her body utterly betrays her, and you can feel her tense up as she's reaching her peak.

You even make her cum once more before you finally pull back, spraying your own load right up the crack of her butt.

She slumps against the wall as you release her but manage to remain on her feet, standing there knock-kneed with your juices dripping off her ass and down the insides of her slender thighs.
