You have a received a text from your Sister-In-Law while out with your wife; once safe you make your way to your Sister-In-Law's bedroom where she asked to meet you. You find her wearing a barely there maid apron and blue panties, she's happy to see you and admits she bought the outfit because she knew it would have a taboo effect on you. Stripping in front of you, she slips into the role of a cock maid, where her job is to drain your balls, clean your cock and keep you satisfied...and she takes her job very seriously. Without removing her panties you fill your Sister-In-Law's pussy with your hard cock, and as filthy words pour from her mouth you fill her pussy with a large load of cum that you watch drip out afterwards. Maybe your Sister-In-Law should be your cock maid more often.
