Step Sis Threesome: Exclusive Best Party Fun

So that step sis threesome honestly started as the most innocent thing, just Anya, Samantha, and their stepbrother chilling after some party with the music still thumping downstairs, and somehow one thing just led to another. I was on the couch when Anya shot me this half-mischievous, half-nervous look and slid her hand up his thigh, and Samantha just laughed soft and leaned in to kiss him, my heart already pounding. Clothes came off slow, piece by piece, warm skin and teasing touches, and when he pulled Anya onto his lap she let out this breathy little moan that flipped my stomach. Samantha knelt between his legs and took him in her mouth while Anya guided his hands to her natural tits, and I just sat there soaking in the wet sounds and quiet laughter. Eventually all three of us tangled on the bed, hands everywhere, nobody in charge, just this easy rhythm building until we were breathless and slick with sweat, and afterward we lay there giggling like nothing weird had even happened.
