Two teen stepsisters, Isa Bella and Rose Carter, are arguing, so their stepmom, Katrina Colt, wants to know what's going on. It turns out that Isa's ex-girlfriend left a strap-on dildo behind, and Rose used it without asking. Katrina is a little taken aback at first since she's straight, but she wants to be open-minded and supportive for her stepdaughters so she offers to buy EACH of them a new strap-on to settle the matter. Days later, Katrina gives the teens the new strap-ons, and they gratefully offer to show their appreciation - by giving Katrina her first lesbian sex experience, including DP and spitroasting!
