Tommy's thoughts were of lust, sex and Ava. He finished washing his hands, in the bathroom opposite his old bedroom, where both Ava and his sister Jennifer were already in the throes of inflamed sexual rapture. At this thought his arousal further stretched the fabric in the crotch of his jeans. The time for thinking was over; now was the time for action.
He stripped completely naked, leaving his clothes in a neat pile by the tub and walked along the hallway to Ava's bedroom; he entered without knocking.
The room was subtly lit by two wall up lighters either side of the bed's headboard. Ava and Jennifer stood between him and the twin bed their clothing strewn around the carpeted floor. As on the previous night, Ava had her back to him. She and Jennifer were locked in a passionate embrace their faces glued together with tongues exchanging bodily fluids. Naked flesh merged with naked flesh. Tommy nearly blew his load there and then. Without thinking, his left hand grasped his hot, rigid cock; wanking its long length he moved behind Ava.
The air was alive with sexual tension amid the musty aroma of two women's intimate desire to fuck. Everything carnal, everything darkly secret, everything sensual, would be shared between them; knowing this only heightened their intimacy.
Tommy's erection pierced the junction of Ava's thighs, gliding easily through warm, sweat sheened skin. Ava's breath caught in her throat, gasping at his erotic intrusion. She broke off her kiss and held Jennifer away from her body as Tommy's hairy balls slapped at her thighs. Looking down at the head of Tommy's prick she saw it disappear as quickly as it appeared. Tommy moved his cock rapidly in and out of this exceptional orifice. Ava tightly held her knees together so she could enhance the delicious sensation of Tommy's cock rubbing between the tops of her thighs. At the end of his second thrust, hot breath and a warm, wet tongue licking around the underside of his sensitive cock head announced his sister's union.
Tommy's hands cupped then lifted both Ava's heavy breasts. Her smooth globes of perfect tit flesh felt wondrous in his hands as they jiggled and shifted under his fondling. Her nipples responded in the only way they knew how, their prominent rubbery peaks ached to be tweaked and pulled then twisted first one way then the other sending a current of sensual sensation to Ava's nerve endings centered in her clitoris.
Ava groaned. A guttural groan deep in her throat as her head leaned back towards Tommy. Jasmine scented aroma filled his nostrils. His kisses were warm and wonderful on her neck. He nibbled her right earlobe. His tongue warm and wet lashed her inner and outer ear. He tasted her jasmine perfume mingled with salty perspiration. She was sexually alive. To balance herself she held on to Jennifer's head, clutching handfuls of fine, strawberry blond hair.
Jennifer watched as moisture surrounded Ava's quim, its musky aroma an aphrodisiac to her senses. It first rolled onto Tommy's cock; adding instant lubrication to his intrusion of Ava's wet cleft. Her lips and tongue alternated their ministrations between Tommy's slick prick and Ava's gushing hole. A sweet bliss enveloped Ava's senses at this superb assault on her young body.
