After the MC and FMC save the MC’s childhood friend from getting raped, they go to the FMC’s house. The Childhood Friend wants to be friends with the FMC, and when she agrees, she immediately goes to fondle her breasts and tease her. It quickly proceeds into a threesome.
Childhood friend has some dialogue about knowing a woman’s touch and groping the FMC is her idea of friendship. It could be implied that she has sex or plays with her female friends, but it could also just be a joke, it’s hard to tell.
