Time for you to have some of your jollies. Lilian can provide you with a nice ride as she is being eaten, so you place yourself behind her.
Before entering, you give her bush a kiss or 2. Lilian's hands form fists like she was trying to strangle you for your presumption, but she is also trying to move her legs to let you have full access to her.

It is not long before Lilian is wet and you stand and get into position. Lizzy looks surprised, but not displeased as you thrust into Lilian and begin some long strokes. You had been thinking you would need to thrust hard to help Lizzy swallow, but that seems not to be needed. Lilian is vanishing into Lizzy's mouth at a reasonable rate. Still maybe on the slow side, but you can attend to your, and Lilian's, pleasure and let Lizzy take care of her meal.
Lilian is a nice lay, and, surprisingly, is enjoying your attack more than you are. Her hands are still fists, but she is answering your thrusts with her own and her body is quivering with excitement. You finish only a moment before her own eruption.

Lizzy has now passed Lilian's waist and you instruct her to replace your tool with her tongue, which she does. Lilian is not thrilled at 1st, but by the time you finish untying her to allow Lizzy to swallow her legs, Lilian is working her way towards another climax.

You are not done yet. Lizzy is in a classic doggie position, with Lilian starting to expand her belly. The idea of you opening her of course quickly fills your mind.
