Bill has a row with his wife about her housekeeping and storms off down the pub with her shouting after him, "And you can sleep in the spare room tonight"
After a few pints he feels a bit guilty because maybe he's being mean to her after all and he makes up his mind to give her an increase. He gets home and the house is in darkness, so he creeps upstairs and as he passes the spare room the door is ajar and he can hear her gently snoozing. With a grin on his face he decides to give her a little treat, so he quietly goes in and sees a soft female form lying face down under the duvet. Down on his knees he gets and starts licking the back of her thigh, working slowly and gently up till he's pleasuring her with his tongue. He hears her giggle then start to purr and moan, before eventually giving an excited gasp and a shudder before sighing and laying still. Giving her a playful slap on the bottom he gets up and says,
"Wait till I get back, if you think that was nice I'm going to give you a seeing to like you've never had before"
With that he leaves the spare room and heads into the bathroom. As he goes in he's astonished to see his wife lying in the bath with a glass of wine and a book and exclaims loudly,
"What the hell...."
She glares at him,
"Shut up you fool, you'll wake your mother. She's come to pay us a visit and she's asleep in the spare room."
