Hi, in 2013/14 the autor MsGrey made a few sequels to "An Afternoon Well Spent" from Mr. Grey. The first one i found on http://www.overflowingbra.com/results.htm?varname=773,
but the 2nd and 3rd were only uploaded on http://www.mcstories.com for a few month before vanishing from the site with the autor all together.
The titel of the 2nd was if i remember right "A Pregnancy Well Spent" and the third is "A Childhood Well Spent".
