First-person perspective (boyfriend POV), a sharp-eyed loli with a defiant smirk, small breasts, cowgirl position having sex, cheeks flushed deep red, body trembling, trying to glare but eyes keep fluttering half-shut, biting lip to hold back moans, legs pressed together squirming, sweat on skin, still muttering "hmpf" under breath but body leans toward you every time you get close, dim room, messy sheets, intimate tense atmosphere, pencil sketch style, delicate shading, erotic power play tension.
