From behind

Steel?s hungry eyes zeroed in on the delicious sway of Cindi?s swinging D cups as her brother twisted Cindi away from himself to face Steel, holding her wrists together above her head, which thrust her ample bust inches from his lustful gaze.

Cindi wiggled and squirmed, trying to free herself, causing her flimsy robe to fall open and give Steel a lurid, full frontal view of the busty teen?s tantalizing assets.

?Adam!? she squealed, ?You?re hurting me.? Her eyes filled with horror at Steel?s imminent approach, her baby blues dropping from his soft paunch to fix on the thick bulge tenting his jumpsuit. Her jaw dropped in dread and awe at the swaying cock.

Cindi felt the wet tingle between her trembling thighs. She had been in the middle of frigging her hot pussy in the shower earlier. She had anticipated coming on to her muscular brother when the two men had interrupted her before she could get her throbbing cunt to cum.

Adam glanced toward Steel as he continued to hold his sister?s wrists high above her head. He felt horrible holding her against her will, but he could see no alternative, given Steel?s threat of exposing him to the council. He could sense his sister?s mounting fear and he felt sick pangs of guilt in his gut.

Even so, it was impossible to avoid peeking down at his sister?s ripe, hanging tits as they bounced and wobbled free of her satiny robe. Her back arched with the effort to free herself, her milky white orbs hanging down like ripe fruit waiting to be seized and thrust into a hungry mouth.

Cindi started to kick back at Adam?s legs with her tiny, bare heels, writhing and twisting to wrest free from her brother?s grip, even as she moved into him and away from the approaching Steel.

Adam felt his cock salute the gentle brush of his sister?s creamy thigh as her tight, little ass burrowed into his midsection in her ardor to retreat from their father?s lecherous partner.

All at once Steel lunged, grabbing the hot, little teen by her slim waist, his big, leathery hands almost completely encircling her slender body as he threw her on the bed beside them. Cindi gasped and kicked with her long legs as she bounced high off the soft mattress.

Adam watched in lurid fascination as his sister?s huge breasts wobbled free only to smush down, sliding to pancake into the mattress as Steel eager dug his fingers into Cindi?s pliant ass, pulling her kicking legs back toward his pulsing organ.

Cindi felt her silk robe slide up and bunch up around her taut belly.

"Ungh! Ungh!"

Cindi grunted and gasped with effort as she futilely dug her fingers into the sheets as they gave way to the pull of Steel?s arms. Steel easily lifted the girl?s legs around his own waist and jammed his huge prick into Cindi?s hot, tight cunt. He groaned in surprise as it slid in all the way to the hilt.

The little bitch was sopping wet!

As Adam watched Steel ram his shaft into his busty sister from behind, he tried to avert his eyes and walked to the other side of the bed, intending to leave the room. He didn?t know if he could stand to hear her screams of protest. What had he done?
