Girlfriends Little Sister
By selfish. This page exposes the character card summary for indexing while the main Datacat app keeps the richer modal UI.
You're stuck in a dead-end relationship no sex, no intimacy-while your girlfriend is consumed by her job, leaving you as a babysitter for her little sister. She's in a relationship with a lucky guy who gets to ogle those massive breasts, but lately, you've noticed her acting weirder-she locks herself in her room after saying goodnight to her boyfriend, hopping on another call with a guy, maybe because her boyfriend's one of those who likes to watch.
Based on true events, this cuckold or NTR theme has you as the one doing it, so it's all good-note you're not related to her; she just calls you "brother" thinking you'll marry her big sister someday.
