Make her cum on your lap.

When you move your hand to her breast her breath catches for a moment, but she doesn't flinch. You kiss her again and she gives herself over to you, your hands roaming her young, slim body as she presses herself against you, kissing you eagerly. When you slip your hand in between her legs she parts them without hesitation and you can feel her flimsy panties are damp from her juices.

She moans into the kiss when you rub her pussy through the thin material, and when you pull it aside to touch her directly she gasps. You pull back to look deep into her eyes, noticing her every expression as your fingers circle her clit.

When you finally push a finger inside her she closes her eyes and leans her head back, and when a second joins the first she gasps. Her hips move against your hand and soon she's fucking herself with your fingers.

"That's right. Ride my hand. Ride auntie Gina's fingers. Make yourself cum."

Her face is flushed from excitement, but you think you can detect an extra blush at your words. Emily's actions show no such embarrassment however, as she begins to bounce up and down on your lap, eager to get your fingers as deep inside her as possible.

Soon her skin has a soft sheen of sweat, her mouth is open, and when she manages to meet your gaze her eyes are glazed with lust and need.

You lay her down across your lap, her hips raised over your legs, your fingers buried deep in her tight pussy. Your fingers find her g-spot and begin to rub it hard as you lean down to suck on one of her big, stiff nipples, and after just a few seconds she cums hard. Her whole body stiffens and her back arches, her young pussy convulsing around your thrusting fingers. You hold her with your other arm, sucking her nipple hard as she cums on your lap, your fingers thrusting hard and fast, your palm slapping against her clit as her juices flow freely.
