Wife gift anal fuck to step son`s secret

The naughty secret behind the swinging doors of the Johnson household was just too enticing for young Billy to resist. He had always crushed on his sexy stepmom Cassie, ever since she married his dad a couple years ago. With her luscious curves, big tits, and an ass that seemed custom-made to be spanked, the 19-year-old Billy often found himself unconsciously imagining all the dirty things he’d love to do to her.

So when he heard whispers of Cassie’s secret life – how she and his dad had an open marriage and she often snuck around with other men – Billy’s cock stiffened with excitement. He watched her every move, day and night, hoping to catch a glimpse of his stepmom in action.

Finally, his patience paid off. One sultry night, while his dad was out of town on business, Cassie slipped into the guest room dressed to thrill in a low-cut top and tight jean shorts. Before long, a mysterious older man arrived. Billy sat outside the door, enraptured, as his stepmom moaned with pleasure, the bedsprings creaking rhythmically.

Despite himself, he begun fumbling with his own cock, wishing it was his hand groping Cassie’s massive tits. Finally, she screamed out in ecstasy, coming hard around the mystery man’s cock. Billy, meanwhile, shot his own load to the floor, it was too hot.

Months later, Billy’s cottage was converted into his own room and in an attempt to minimize conflict, Cassie wasn’t allowed to enter his room at all. Things went smoothly until one rainy night…

With a loud bang,outing Cassie burst into Billy’s room, breathless and soaked. She was dripping wet, thighs trembling, barely keeping it together but there was only so much she could take… Before Billy could react, she launched herself at him, smashing her lips against his! Her fingers tangled in his hair, holding him close, grinding her breasts against his chest.

Then, with a coy little smile, she turned around and bent over, pulling her shorts over her ass, revealing her shaking, juicy rear. God it was divine.

Young Billy, usually soft-spoken and shy, found himself taking matters into his own hands. His calloused palms ran up her outer thighs, squeezing the meat of Cassie’s ass, causing her to shiver. Cassie moaned, pushing her butt back.

Popping open the button of his pants, he whipped out his massive member, swollen and needy. He slapped it against Cassie’s ass cheeks, enjoying the way she wiggled. Then, planting his thumbs in her crack, he prised open her cheeks, groaning as he saw her tight, pink little hole winking back at him. He rubbed the tip of his cock against her puckered entrance.

“Oh fuck Billy…” She moaned, tilting her hips up, giving him better access.

Without further preamble, he thrust forward, burying himself balls deep in the tight, velvety clutch of her ass. Cassie screamed, back arching as Billy began thrusting hard and fast, his balls slapping against her pussy. The filthy wet squelching sounds of his cock ramming into her hole filled the room as he plowed into her, his stepmother pushing her ass back to meet him stroke for stroke.

His cock was buried so deep, stretching her hole so wide open… and she fucking loved it, clenching down on him like a vice. He reached around to grab Cassie’s huge, soft tits, tweaking her nipples as he pounded into her pussy. She moaned and writhed against him, completely lost to pleasure.

“FUCK, Billy!” Cassie cried out, fingers scrabbling uselessly against the headboard. “You’re so big… so fucking deep… don’t stop, please…”

She pushed back against him, wanting him to fuck her harder. Billy obliged, his rhythm becoming erratic as he chased his pleasure. He pistoned into her ass harder and faster, grunting with the effort.

“Gonna… gonna cum… in your ass… cum on my fucking cock, you dirty… fucking… slut!” Billy growled. Cassie keened urgently, clenching around him. He reached down to roughly rub her clit, pushing her over the edge as she came hard, shaking and bucking against him.

That pushed him over the edge too, and with a roar, Billy buried himself to the hilt and came hard. Stream after stream of his hot seed flooded into Cassie’s clutching asshole, filling her up to the brim. Billy collapsed forward, pinning his shuddering stepmother to the bed.

Cassie whimpered happily, feeling Billy’s cum leaking down her thighs. She’d never been filled so deeply before. She couldn’t stop shivering. “God… that was fucking amazing… you fuck me so good, Billy…” she purred, reaching back to stroke his hair. “I think this might be the start of a beautiful relationship…”

And so began their secret affair, behind closed doors. Their new favorite game: an illicit, incestuous coupling that threatened to tear the family apart – just how they both liked it.
