Grandparents X***/*
Short review: This site is still new, but what it lacks in numbers, it makes up for in sheer perversity — not to mention it comes in multiple weekly doses, and in 4k HD no less. Yeah, if you're into the old/young genre, this looks to be a sound investment.
Content Amount: Only 20 scenes and set but with more coming in bi-weekly, that's sure to change soon.
Content Quality: There's an amateur vibe to these productions, but the crew puts in a good effort, and the end result is available for stream or download in 4k HD. Works for me.
