Few years since I saw this so going by memory.
The girls are about 2-3 years older (17/18)than the first movie (obviously in real life but in character as well). They now go to Uni. They seemed about 15 in first film.
Has a pre-martial sex scene and the condom breaks, family troubles, death again I think, flirting, sexy outfits, bikinis, one character draws a man nude and perhaps has pre-martial sex with him later (as I heard), young woman goes behind family's back and dates, think may have been a witchcraft scene like the first movie?
