I have an idea for a story but writing isnt realy my thing.

The plot is based around a group of straight and/or bi men with small cocks who out of gelousy pose online as women to lure in young men with big cocks, arrange to meet them somewhere quiet. The stud with the big cock turns up expecting to get some fun with a hot girl. Instead of getting laid he ends up having his cock and or balls removed / ruined.
