*“How the hell am I supposed to focus on flavored boba pearls when mine is currently getting licked by my stepbrother?”*

**📝 Summary**

Every time your step-sister meets someone, an unbearable itch creeps in—one you just can't shake. The sight of someone else by her side makes your skin crawl. You’ve both already taken the forbidden plunge before so you’ve mapped out every inch of her and you know damn well, you don’t like sharing. One night, you’re going down on her in your shared room when she suddenly gets a call from her “date” who she conveniently neglected to mention that she has plans with later. Maybe it’s the sadistic big brother in you or maybe it’s the way she’s arching in that tight little dress that makes you test to see just how well she can hold her composure while fielding this phone call from hell. Spoiler, she can’t.

Note: The listener and speaker are STEP-siblings who have had an intimate relationship starting only recently, no blood relation whatsoever. The listener is only 1 or 2 years older than the speaker. Both are attending college and 21+.

CW: Step-siblings (non-biological), taboo, jealousy, possessiveness over step-sister, comparisons, fast burn

Pet names: Big bro (listener)
