Sister's a gamer, I'm inside her and she doesn't notice

A woman with silver hair lies on a fluffy rug, focused on a fighting game on TV, wearing a pink top and plaid skirt. A man's hand pulls down her black thong as he enters her from behind, her body tensing slightly. The camera stays close on her hips and buttocks as he thrusts, her attention still fixed on the screen, surrounded by plush toys and a casual living room.
