The girls know each other really well, and are always being checked up, so there shouldn't be too much issue.

I've ALWAYS wanted to stack one on the other, face down on the bed, spread both sets of legs and alternate between the two pussys as I felt like.

Imagine that! Savouring the subtle differences in tightness and fit in REAL TIME. Not relying on memory!

Are we NEVER to experience this??

Can't some girls, somewhere, work this out?
