Spying on Step Sis's Sexy Slumber Party with BFF

Evelin Stone and her tiny blonde friend Anastasia sat tangled on the couch and something inside me refused to walk away. Fingers slid fabric from shoulders and thighs while lips grazed collarbones, then lower. Evelin circled Anastasia's pink nipples with her tongue, pinched them hard, and peeled the wet panties down slender legs. She held her friend's knees wide open, spread the glossy folds, and dragged her tongue over the swollen clit with one slow, filthy lick. Anastasia begged. Evelin sucked harder. The smaller girl's body jerked, then seized, spine arching as the orgasm crashed through her. They switched. Anastasia knelt, mouth greedy, and Evelin lifted her hips, grinding her ass in wet, urgent circles against that searching tongue. Evelin shook when she came, thighs trembling. They scanned the room, but never spotted me watching their soaked, stolen moment.
