Home from school, hot and bothered, horny and wet. I lie on my bed, legs up, knickers off. Hand instantly down between my legs, fingers stroking my bald smooth pussy, eyes closed. Bliss!

The new water pump is fitted. He goes upstairs to check the hot water tank. Thirty eight years as a heating engineer, looking forward to retirement. He gets to the top of the stairs, and heads to the airing cupboard.

He passes the partially open bedroom door.

My eyes closed. Legs wide apart. Two fingers in my wet vagina. In heaven.

He stops. Stares. Disbelief. Aroused.

"Hello".
