Fuck Traci from behind

I levered myself up, looked Traci in the eyes, and said, “Get on your hands and knees.”

She looked a little startled, but a lustful grin slowly took over her face. She looked at her sisters and purred, “Oooh, our hornball brother takes charge. I like it.” She got into position, shot me a sultry look over her shoulder, and waggled her sexy ass invitingly. If her tits were a little smaller than her sisters’ melons, it was only a little, and they swung freely with her movements; she bent her elbows a little to lower herself until her nipples were just touching the sheets, then brushed them back and forth, enjoying the stimulation.

I was transfixed for a moment at the sensual spectacle before me. Traci gave me a smoldering look and asked, “You like my big titties, baby?” I moaned a little as I got up on my knees behind her and took them in my hands, squeezing them lightly and running my fingertips over her stiff titbuds. “Ohh, yeah,” she said huskily, “you like my big titties.” She lifted a hand from the bed for a moment to reach back between her legs. She grabbed my throbbing cock, squeezed it lightly, and said, “Why don't you do something with your big fuckpole to show me just how good they feel?”

I grabbed Traci’s ass with both hands and shifted her around a bit so that we could see ourselves in the mirror on the bedroom door. She gave me a sultry smile in the mirror and murmured, “I like the way you think, Mike.” I’d never really thought about a woman’s back as sexy before, but she had a really sexy back—nice muscle definition, long clean lines tapering down to her waist to flare back out to her tight, firm ass. I leaned forward and ran my hands along her soft, smooth skin to her shoulder blades, then outward (just brushing the sides of her breasts) and back down her sides to her hips and legs.

In the mirror, I saw Jessie and Marisa position themselves behind us so that we could see them as they began to play with each other. Suddenly, I couldn’t contain myself any longer. I took a firm grip on Traci’s hips, and with a convulsive thrust of my own, I buried my cock in her smoking-hot cunt. She was dripping wet, but also surprisingly tight, and her pussy spasmed around my shaft; she tossed her head back with a loud gasp, making her long ponytail bounce between her shoulder blades, then shivered through a mini-orgasm. She moaned, then looked at her sisters’ reflection. “Fuck, Marisa,” she said throatily, “you weren’t kidding.”

Marisa could only moan; she had her mouth full of one of Jessie’s tits and her fingers diddling her sister’s clit, while Jessie was fingerfucking her. I looked at them, then at Traci’s face, eyes heavy-lidded with pleasure; then, as I began to move slowly in my step-sister, I looked down and saw my cock framed by her ass cheeks. It was an erotic feast for the eyes. “Harder, Mike,” Traci moaned. “Fuck me harder.”

I leaned forward, sliding one hand around the front of her hips to the furry mound above her pussy. I loved the feel of her soft, neatly-trimmed bush on my palm as I slid two fingers into her slick twat and began to stroke her clit. At the same time, I reached down to one of Traci’s big, free-swinging boobs and captured it with my other hand. Figuring the time for gentleness had passed, I squeezed her firm titflesh and pinched her nipple hard between my thumb and forefinger. “FUCK, yeah!” she gasped, and I began picking up speed and force quickly, fucking her deep and hard. Her increasingly erratic moans were a counterpoint to the creaking of the bed under the four of us and the wet slap of my balls against her twat that punctuated each thrust.

Traci’s moans got louder and louder as I pounded her cunt, and her sisters’ moans rose in volume to match her. Her pussy was tight, wet, and incredibly hot; if I hadn’t already cum so many times that night, I’m sure I would have not only cum but passed out already from pleasure. As it was, I had just enough consciousness remaining above the crashing waves of sensation to think of a way to heat things up even further.
