My wife is very conservative but through fantasy, roleplay and some very positive responses to online posts she is beginning to loosen up. Our son goes to bed at about 9 every week night, so from about 8 I would start complimenting and touching my wife till I managed to get her to take off her bra and panty, stroking and touching the whole time. Last night we even got her naked in our room and I had just put in her buttplug when my son knocked on the door to say he is ready for bed.
She was so aroused that she just put her long tshirt on to go and say good night. She subsequently surprised even me by taking off her tshirt as soon as she left his room and was even willing to have sex for some time with the door open.
