In a heated exchange, a sister demands her brother's full attention, commanding, "Suck me, boo." Unwilling to back down, he obliges, engulfing her engorged clit with his eager mouth. She moans, grinding her hips, as he explores her slick folds, teasing her entrance with his tongue. She grabs his head, pushing him deeper, craving more. He obliges, plunging two fingers inside her, curling them upwards, stroking her G-spot. She shudders, her orgasm building, until she finally erupts, coating his face with her sweet nectar.
