Most mature porn doesn't really get into age specifics, figuring that those who are watching will be sufficiently impressed that these older ladies can get it on with such obvious skill. Nifty Fifties sets the bar a little higher, stating that the ladies in question are at least a half-century old, and inviting you to watch them fuck the way only ladies of a certain age can.
Easily the best scene on the tape is the first one, involving Dalny Marga, who doesn't look anywhere near 50 and who fucks like a teenager. Dalny looks wonderful with a cock in her mouth and her body is tight as hell as she gets boned inside the hull of an old car. This will not only cause murmurs of appreciation among viewers, but also get those cocks out for some serious stroking. The years of experience show through in the luscious blowjob she gives, and the thrill of taking a face full of cum seems to make her quiver with delight.
The other two scenes, involving Tabitha Hart and Asian Lei, aren't quite as well-realized. The sex has its moments, but can't compare to the first third of the tape. Still, you can't deny the joy of watching women who could be your mother squealing like the first girl you ever fucked. That, in itself, makes the whole package worth watching.
