As many of you noticed, I posted the final chapter of Marcie's Visit To Her Grandparents.
Our heroine's descent into decadence in the year since she turned 14 reaches new depths visiting Gramps and Gram. In the fourth chapter she witnesses things that most teenagers never imagine.
First, it's a 16-year-old separatist who's identified a special way to fill her sex sleeve with a real cock. Then she and others watch her mother revisit a practice from her teens and demonstrate it to Marcie, leaving the girl in shock.
