Looking for an old story

Story by saronus

Hey guys,

Long shot but I thought I'd ask, I'm looking for an old story where a guy dates a futa (maybe shemale?), she takes him home to meet her sister & mom who are also futa and he lets them all use him. Think there's some inflation in there as well as huge/unrealistic sizes? Might also be some horsecock as well? Been a long time since I read it.
