I admit I was secretly pleased to learn that she'd immediately cut him off (ended up being 4 months) so for a time the only seed her fertile body was absorbing was mine (she was on the pill, but still, the thought counts).

When I returned home she quickly found some replacements, and collected their cum too well before hubby was finally allowed back in because she relented.
