That suspension for the boys is apparently questionable would seem to throw coercion into doubt, so maybe your “vibe” is right. As disagreeable as the notion may be, possibly the girls have claimed rape in an attempt to keep themselves out of trouble?

In some states all sexual contact under the age of fourteen or thirteen is considered rape.
