A Rock and Roll in the Sand

 Flash takes Pinkie Pie's sister out for an evening of getting very close to some fine sedimentary specimens. Or to dick her down good on the beach. Same thing to the cute geological scholar!

I've been wanting to do the From Here to Eternity thing for awhile now, and figured it would involve Flash, but wasn't sure who his partner would be. Then various puns worked themselves out in my head, plus a long time ago I did say that, having fucked all of his girlfriend's friends, he also needed to do their sisters, so...Maud! Also that means your time will come, Limestone and Marble...
