Tim does Kim

Tim places his hand on his sister's which is still on his thigh. "You really want this then" he asks?

"You do not know how much" she replies love showing as she tenderly touches his hand.

As if I am no longer there the magic of desire, want and passion take over for the two siblings.

Kim stands she is in her mid 20's and has the firmness of her youth as she starts removing the uniform. To say the uniform hid some very beautiful things would be an understatement as her breast almost spring away from her chest, her bra barely able to hold them contained, the shadow of her nipples pushing the thin material out showing off their shape.

Tim joins her standing and removes his own shirt, their clothes pooling on the ground as they embrace and kiss, not the brotherly and sister type quick kiss but a long enjoyable getting to know you kiss. Each pair of hands caressing and exploring as they undo pants and zippers and soon are standing in just their underwear.

Her hand dips down into his briefs and he gasps and then thrusts his tongue into her mouth as they duel for who is in charge. She has him out and is rubbing his hard cockhead against her stomach as he rubs her pussy through her panties and then she is gasping as he thrusts a finger inside her after pushing the thin material to the side and then another.

"Oh God Tim, yes" she cries out as her body shakes with his finger fuck.

They fall to their clothes and as he grabs her hair and she parts her legs within a few breaths he is inside her and thrusting meeting her gaze as she looks up at him, the love from them both so full and passion filled.

Their movements match one another and he is thrusting in and out of her pulling fully out of her with a sucking sound and then impaling himself inside her again and again, her tits rocking back and forth as he grinds into her harder and faster still.

"I am so close" she moans.

"Oh Kim, God take me now" he adds to her moans as they both crash together pelvic thrashing wild and crazy for a moment then total stillness as he lays on top of her stroking her hair, kissing her mouth tenderly.

"I never knew" he says tenderly.

"I only hoped" she answers as he slowly shrinks and slides out of her wet filled pussy.

"That was amazing" I tell them bringing them out of their lost moment to the present.

With embarrassed looks they both redress and Tim takes the portable light as I lead them to the barn we are staying in down the road.
