"What if I was to be your first?"

Celeste eyes go wide with shock, "Y-you? Um, You're very pretty, but I'm not a le--" You gently shush her and walk over to her. You kneel down affectionately rub Lili's head, asking her to move aside for a moment. The raven-haired gets gets off her sister's lap and watches you with interest. You grasp the breast that was in Lili's mouth and begin softly rubbing the drool-covered nipple with your thumb. Celeste gasps at your touch but doesn't fight it.

As you gently massage the the tan girl's ample breast you tell her to close her eyes and relax. You say she should focus on the pleasure of your touch and let everything else just melt away. She does as you say and you begin massaging her other breast with your other hand. As you knead her breast you begin kissing her neck causing Celeste to shiver at your affectionate touch. You kiss your way down her neck until you reach her breast. You then take her erect nipple into your mouth.

Soft moans escape Celeste's lips as you suckle at her teat. You take that as a sign to take thing further and glide your hand down her bikini bottoms. She squirms slightly as she feels your fingers rub against her warm slit. Her pussy is already slick with excitement, coating your fingers in her juices. You slide a finger into her wet hole causing her body to tense up for a moment. Slowly move your finger in and out of her pussy, letting get used to the feeling. You then insert another finger, massaging her g-spot with tenderness.

Her moans have grown louder and you can sense that she's on the verge orgasm. Just as she's about to reach climax, you stop and stand. Celeste opens her eyes and look at you with yearning confusion, "Please...don't stop." Her voice trembles. You tell her that if she wants you to bring her to climax, she'll have to do the same for Lili afterwards. Celeste looks at her younger sister who is watching intently and nods desperately, "Okay... Just please keep going." She pleads.

You kneel in front of Celeste and slide her moist bikini bottoms down her toned legs, the musky scent of her wanting pussy wafts in the air. You position you head between her legs and glide your tongue around the edges of her pussy, flicking her clit with every pass. Her hand grips your head as she watches you tongue her sweet hole. You thrust your tongue inside her, causing her howl in pleasure. Your tongue explores her inner walls, leaving no inch untouched.

Celeste begins instinctively grinding against your as her pleasure builds until she explodes as your tongue probes her g-spot. Celeste cries out in orgasmic ecstasy as you lap up her divine nectar. Her body convulses and writhes in blissful rapture as she is wracked by multiple orgasms.

As she comes down from her euphoric high, you move your slick face away from her dripping slit and stand up. You then lean down and kiss Celeste on the lips, jamming your tongue in her mouth to let her taste herself. She kisses back with the little energy she can muster after such an intense experience.

You break the kiss and let her rest for a few moments before making sure she keeps her end of the deal.
