What's next?

Diane leans her head down, and kisses Cindy full on her lips. "Umph", you hear Cindy moan again. She opens her lips, and you see their tongues extend toward each other. You can feel from the throbbing in your cock how this has effected you. Diane's pace in kneading and pinching Cindy's young and pert breasts intensifies. Cindy reaches back with her right hand and runs her fingers into the top of Diane's bikini bottoms, and down to her pussy. It causes Diane to arch her back and again place her open mouth fully over Cindy's.
Diane then quickly pulls her mouth away and tells Cindy "I must have you now!"
Cindy repsonds by saying, Oh, no Diane. Please, let me enjoy you first."
Without another word, Cindy parts their embrace and turns toward Diane.
She reaches up slightly and places her hands full on Diane's still covered breasts. She slowly hefts them, and says "These are wonderful." Her face moves into Diane's cleavage and she begins to run her tongue along the edges of the fabric. After a few swirls she plants kisses on Diane's tits and then runs the tip of her tongue over the nipples. Even with her top on you can see Diane's nipples getting hard. And then, Cindy takes her right nipple between her teeth and bite gently.
"God! Where did you learn that at your age?" Without a word or hesitation, Cindy moves to the left nipple and does the same.
Its having quite an effect on Diane, because she then leans slightly and squeezes Cindy's firm ass.
