I fucked my wife's friend when she came to look for her and she wasn't there.

The doorbell rings unexpectedly, interrupting their intimate moment. Sarah, still naked from her shower, hurriedly wraps a bath towel around herself and goes to answer it. Her friend Anna is standing there, looking nervous."Sorry to bother you," she says,"but I'm looking for Liz. I need to talk to her urgently." Anna's presence arouses Sarah, who is secretly curious about other women. She decides to take advantage of the situation and suggests that they should wait for Liz together in the living room. As they sit down, Sarah moves closer to Anna and starts massaging her leg. Anna seems uncomfortable at first but gradually relaxes under Sarah's gentle touch. Sarah then leans in closer and begins kissing Anna's neck, moving slowly down towards her breasts. Anna gasps when she feels Sarah's warm breath against her skin.
