Mackenzie Mace and her stepbrother Nicky Rebel seem to be fucking on the regular. One morning before school, Nicky fucks Mackenzie in the kitchen, but they are interrupted by their stepmom, Vivianne DeSilva. The alluring stepmom notices Nicky’s boner and sucks him off right there but finds Mackenzie’s panties and becomes suspicious of what’s going on between Nicky and Mackenzie. Not too long afterward, Vivianne walks in on Nicky and Mackenzie fucking, and joins in on the fun.
