Your slutty housemate has just come back from a festival and she wants to play. She opens her legs and lures you into a game of 'you play with yours and i'll play with mine' before you realise you're following every single one of her entrancing jerk off instructions. She wants to cum at the same time as you, and you edge yourself as your watch her sliding a toy in and out of her pretty pink pussy, right there on the stairs. Another housemate could come back at any minute! Your dick erupts with the cum that she craves.
