Script: The scene I have in mind involves the single mother of a young teen son dealing with her annoying family at some event (maybe a wedding or an engagement party). She only attends these things out of obligation because she's long been treated as the "black sheep" in the family, due to her becoming a mother at an early age, dropping out of university and never marrying. After a few too many she feels the need to get away from her family for a moment and retires to her room. Her son walks in and expresses concern and after some talk about her family, she thanks him for being so sweet. She gives him a little kiss but notices when he pulls her in tighter. She pulls away and apologizes for her reaction. She then says "I know this probably isn't the right time, but there's something I've been meaning to ask you." Their conversation evolves/escalates from one about him "growing up" to a confrontation about him peeping on her and stealing her undergarments, to him admitting his sexual attraction to her. The mother is shocked initially but the son turns the tables and confronts HER about being flirty with him and giving peeks of her body. After some back & forth, the mother says "fuck it, maybe my family's right about me. But who cares?" The scene then becomes a frank discussion about masturbation when the son further shocks his mother by admitting that he has a very specific fantasy when he jerks off - cumming inside of her. The mother is shocked, but the rest of the scene follows the breakdown of her inhibitions and eventual surrender.
