To everyone who saw this from thekzx (https://inkbunny.net/s/2842355), I decided to uploaded what happened while the belting was still going on (and so we can see what Fiona looks like)
Some background info for both this pic and thekzx pic: The twins (Tay and Izzy) when they were like 8, went to visit their Aunt Fiona and Uncle Dale for a week in the summer in the country. They have 3 kids (Owen 15 at the time, Kyle 8 at the time, and Tammy 6 at the time).
Tay and Kyle get into trouble at some point, probably from fighting and it gets physical, and Fiona decided to spank them, so she told them to go pick a switch, but Tay decided to be a smart ass and choose a blade of grass.
Fiona was in no mood for Tays antics, so she sent Tay to the couch and tells him to wait for her, because she has a "reward" for his smart idea. Tay smirks at his cousin thinking he just avoided a switching, and sits on the couch, while Fiona and Kyle head to Kyles room for his punishment. Fiona gives Kyles bare butt a caning with the switch while he is leaned over his bed.
Once Fiona finished with Kyle, she went to deal with Tay. She tells Tay to pull his shorts and undies down and lean over the couch. Once Tay is all ready, she takes her belt off, and belts his ass raw for his "brilliant" idea. Since he was going to be a smart ass, she would give him a smart ass.
The pic above happens while Fiona is belting Tay. All characters belong to
P.s. Thekzx has confirmed himself to me that this series of Fiona spankings I commissioned from him are 100% canon. So they happen in the main Mcintots universe (around 2018 their time)
