Shoot A Clone into Grace and Have Fun!

"Two of you huh? that sounds fun. Y'know what'd be cooler though?" you say edging up to her bed and leaning over Grace.
"Two of me", as Grace opens her mouth to respond, a puzzled look on her face, a tiny ghostly ball shoots out of your (Tasha's, really) chest and through Grace's lips. She falls limp on her bed and her eyes go blank as your clone begins to assert its control over her. You, possessing Tasha's body, sneak in some sister-on-sister fun by groping her breasts while your clone asserts its control over her.

After 'big sis' finally comes to her senses, eyes glowing a ghostly blue before returning to normal, she flashes you a wink. Your clone has successfully taken over Grace, now both of the thick Jamaican sisters are under your complete control.

Quickly shutting and locking the door behind you, you go back over to the bed and sit on Grace's lap, your legs locking around her waist. Wordlessly, you lean in and tilt your head to the side as you begin making out with your body's elder sister. Your hands reach for her breasts, and begin caressing and massaging them meanwhile 'big sis' reaches round you and starts feeling up Tasha's soft cushiony ass.
One of her hands comes back around and wriggles down the waist of your short-shorts, starting to flick the bean for you. Letting out a moan of pleasure while exploring Grace's mouth, you think to yourself how you didn't figure this possession stuff sooner, it felt amazing!
