Saving Them Both For Marriage

A stepmother, Dee Williams, catches her stepson, Tyler Cruise, and his girlfriend, Lilith Grace, while they're trying to figure out ways to get intimate without losing Lilith's virginity. The teens explain that Lilith's conservative family believes in abstinence until marriage, so they want to find other options to satisfy their desires without breaking the rules. Supportive Dee begins suggesting different ways to engage in foreplay, but the teens feel unsure about where to start.
Dee proposes that the teens engage in foreplay in front of her for some hands-on guidance. Although Tyler is bashful, Lilith welcomes the opportunity for expert advice, so they agree to give it a try. Dee instructs the teens on various foreplay techniques, and as they explore them, they all start to feel more excited.
She then brings up the possibility of trying anal sex as a way to maintain Lilith's virginity. Though the teens confess they haven't attempted anal sex before, they are open to the idea. Surprising the teens, Dee offers to demonstrate anal sex by allowing Tyler to penetrate her instead.
This way, she can teach them how to engage in anal activities safely. With their arousal building, the teens agree to the proposition, unable to contain their surging desires any longer. As a result, the three engage in a threesome, with Tyler engaging in anal sex with Dee first and then putting into practice what he learned by being intimate with Lilith.
