The Roommate

I've been with Alexandra for a few months now, she's living in my city to learn the language and maybe to get away from a too stringent everyday life. She lives in an apartment with a very nice roommate. In the evening we come home and in the kitchen after dinner we start kissing and touching each other. We start licking each other on the kitchen sink, suddenly a small noise sends a shiver down my spine... I look over and see Lene, the roommate, looking at us and touching herself while her gaze is just outside the doorframe. I'm the only one who notices her presence...she leaves for a moment and comes back shortly after with a dildo and continues to masturbate. Her moans mixed with ours are also heard by Alexandra. The game of glances goes on... the pleasure continues...
