He tries to leave

Adam felt his feet moving under him unbidden. He saw his sister?s come-hither eyes peer up at him, hooded and glazed over with lust, a little moan escaping as her mouth lolled open. His mind felt foggy. How could this be happening? He needed to stop this. He should never have let Steele bully him into this betrayal of his lovely sister. It had been the lustful impulse of a moment.

Stunned, but curious, he followed the buxom teen vixen?s eyes down to where they were looking--at his bulging crotch. He was surprised to see the thick hard-on stretching his form-fitting uniform pants. His huge cock pushed out angrily, almost a foot from his tensing stomach, straining at the button holding them closed. Adam felt it pulling tight threatening to rip free and send the button flying into the wall like a bullet from a gun. His cock ached to fuck his cock-teasing sister.

Steele watched with fascination as he felt Cindi?s hot, teen body succumb to the pounding she was taking from his throbbing member. Looking down at her fine ass pumping his slick cock, he was on the brink of erupting his load all over her lily white flesh of her supple ass. He was equally fascinated by the slow approach of her brother.

?Damn, the kid?s hung like a horse!? He thought, watching Adam and his burgeoning cock approach the other side of the single bed, waving like a weapon in front of him inside the uniform pants. ?I wonder if she can swallow all that??

Cindi lewdly stuck her tongue out and licked her dry lips at the sight of her brother's erection, starting to unconsciously fuck back against the steely rod invading her clutching pussy. Why did it have to feel so damn good? She imagined it was Adam?s cock, the one inches in front of her face that was fucking her like a dog in heat.

?No! I can?t be doing this,? her mind protested, even as she felt the fat shaft setting her quim on fire with overwhelming pleasure. ?I?m not like this! I can still get away...I...ohhhhh gawwwwd!?

Steele slid his finger to jab at her pleasure knob and felt her lithe body tense with an unexpected release. He felt her legs tremble around him as her orgasm rocketed through her loins. Steele could see what they both wanted. It made the puffy head of his dick tingle near orgasm to think about the siblings getting it on right in front of his leering eyes.

?Stick it in her gob,? He croaked the order. ?Fuck her face.?

The command pulled loose some knot in Adam?s will and his hand went to his zipper, sliding it down in one stroke, his straining schlong finally springing to the cool air, jouncing like a baseball bat, coiling to unwind and hit one out of the park. The site of his sister?s little body spasming and crying in pleasure sent his lust into orbit, hungering for a piece of her delectable ass.

He had stopped his approach now, inches from his sister?s angelic face, which was flushed with her arousal. As he looked down at her sweet visage pushing forward at his hard cock (Steele was thrusting into her with even more fervor) he was captivated by the lush blonde curls swaying on the silky smooth skin of her backside, the hair still damp from her recent shower. The smell of her moist sex awakening something animal deep inside him.

?No, Adam, not like this.? His conscience was pleading his sister?s case even as Cindi?s groans of fevered lust filled his ears. The rutting she was taking from Steele?s stiff pole finally crumbled her shaky resolve. Her cries of exertion were becoming mewling, gasping, hungry howls seeking sexual release.

?Hell, the old guy was fucking the shit out of her!? Adam thought. He heard the lewd slapping, sloshing sound of her love box being assaulted again and again, filled with Steele?s thick staff. He saw the strain and ecstasy on his father?s partner?s face as the old man played out his long held fantasy.
