Sounds like Adam and Eve was offering a composite video of two films, Rump Riders (http://www.cduniverse.com/productinfo.asp?pid=6394926) and Every Woman Has A Fantasy (https://www.amazon.com/Every-Woman-Has-Fantasy-VHS/dp/B00008T6PF), which are both available easily (see links), but finding them on a specific tape together would be a lot more challenging, and the quality would be quite suspect (magnetic VHS tape degrades over time, and with multiple plays). Adam and Eve often offered tapes (and later, DVDs) that were combinations of multiple films, as giveaways with a paid order.
