Resorts secretly records and sells unsuspecting couples' sex tapes

An enterprising or fun loving couple could turn that bad situation into a really fun turn around joke. What if they knew they were going to be sound recorded they could make with great giggles a fake sex tape lasting about 2 hours. Use your imagination about the dialoge and sound effects.

It would be particularly funny if the aforementioned fun couple were about 80 years old and extremely embellished the vocabulary, volume, emotion, procedures and descriptions. Much fun indeed. Then just play the tape while remaining very quiet .. if they could. HB of CJ
