In one scene a male character kisses, licks and sucks on a female characters feet/toes and kisses up her legs and stomach. This is not explicit but very erotic and ends with the characters making out whilst laying down. (Male fully clothed, female in mini skirt and vest)
In another scene a female and male character kiss passionately in the rain, the scene then cuts to them making out on a bed, it is dark but implied they are naked. Later on we see them waking up together, implying they had sexual intercourse.
