You love the size and smell of them, and your Mom has begun to notice you getting aroused and her Big panties going missing.

You know dad doesn't really put any effort in to their relationship anymore and you cant understand it as you think your Mom is the hottest woman you have ever seen. You find her in the kitchen making something for dad who is almost nodding off on the couch in the other room. You don't know what comes over you but you unbutton her jeans and pull them down so her massive granny pants are in their full glory right there in the kitchen. Wow, she looks fucking incredible! you are so hard in trousers, Mom playfully tells you not to but you know she loves it really. You dare her to go and give dad his beverage with her jeans still round her ankles big pants on display. She's a little embarrassed but does it while you watch. She come back and tells you to go to your room and you notice a big wet patch in her Granny pants where she is so turned on. Next day she comes back from taking dad to the airport, you both confess to each other how bad you want each other, you tell her about your massive granny pants fetish which she already has a feeling you have. She strips and you fuck her while she begs for you to cum deep inside her as she ovulating and wants lots of little ones with you. As punishment for dad not giving her any attention he will raise his own grandkids xxx
