"Alright, if you girls what this. who are we to object" Aquin assured. "YES" all four girls cried out in joy. "also... it's pretty clear who's going with who" Long remarked as Jade and be took as escorting arm lock as the girls escorted the boys to their sleeping area.
Before long each couple was ready atop each girl's clamshell as the fun started in the pairs of Amber and Aquin, Jade and Long, Katie and Nigel, and Molly with Lucas, all locking lips as they laid down on the soft interior as the clamshells closed up with them inside and once all were closed each girl felt it as the scales covering their viginas moved away to allow the now exposed cocks of their partners to spear them which they all did.
