Sharing 'cock cum stories' with your sister is extremely inappropriate. Family is a place of love, care and positive interaction. Such vulgar content has no place in family communication.

In general, the combination of 'gay' and 'cum' in the context of a vampire story is not a common or acceptable theme in traditional literature.
