Mary sees purple

Mary's eyes are glued to the purple monster in your hand. A tiny pink tongue licks her lips as she contemplates the question. She says, "I want that thing first, but ..." An odd look crosses her face before she finishes her sentence. Her eyes flick over to Kat's recumbent body. She gathers her courage and finishes, "... I'd like her to start using it on me."

Kat looks up from her reverie and sees the lusty flames in Mary's eyes. She grins and says, "Oh, my. What a wicked thought."

Katherine and Mary switch places with Mary lying back on the bed after removing her panties, and Kat kneeling next to the bed. You lie on the other side of Mary, stroking her face and kissing her neck. The buzz of the vibrator fills the room, and Kat touches it to Mary's inner thigh. Mary giggles a bit at the touch, but soon is gasping at the intensity of the vibrations on her lower lips. Your hand strokes Mary's side and brushes against her modest but perky tits, revealing that she isn't wearing a bra. You grab a handful and squeeze through her dress, making Mary moan. Kat barely touches Mary's clit with the purple machine, and then plunges it into her tight wet opening. Mary thrusts her hips up to meet the descending plastic cock. You lean over and kiss Mary, sucking her tongue into your mouth, as her fingers entwine in your hair. You roll her nipple between your fingers through the silky material, and she moans into your mouth. You stretch the elastic neckline of her dress around her right breast and begin flicking your finger across the now-naked nipple.

Katherine alternates between plunging the device into Mary's cunt and playing it across her clit and pussy lips. Mary’s hip thrusts and moans are speeding up, so you know she is close. You break your kiss and move to her luscious tit, just sucking Mary's nipple into your mouth, when her body erupts into a thrashing orgasm, her legs rhythmically clenching around Kat's hand. A long low throbbing cry rises from Mary’s lungs. As her pulsing body slows, Kat removes the vibrator from Mary with an audible squish.
