Stepmother Voyeur: Teaching Her Adult Stepchildren Sex

Beatrice had been forty-two for three months when the watching stopped being accidental and became the thing she lived for. She had married their father six years earlier, and Gideon and Talia had already been grown, college-aged, moving through the house with the easy arrogance of people who no longer needed a mother. Gideon was twenty-two now, broad through the shoulders, dark hair always a little too long. Talia was twenty-one, all long legs and a mouth that looked like it knew secrets. Beatrice told herself, for a while, that she was only checking on them. Doors left a few inches open. Light spilling into the hallway. Harmless.

It was not harmless.

For a year she had paused outside those doors the way other women paused at shop windows. Talia’s room first, most nights. Beatrice would stand in the dim hall with her palm against the wall and watch her stepdaughter peel a sweater over her head, watch the bounce of her breasts as the fabric cleared, watch Talia stand in front of the mirror in nothing but a pair of pale blue panties and run a brush through her hair. Talia never hurried. She would hook her thumbs in the waistband and slide the panties down, step out of them, and stretch, arms overhead, the dark thatch between her legs visible if Beatrice shifted half a step. Sometimes Talia would sit on the edge of the bed and lotion her thighs, working the cream high, her fingers disappearing for a second between her legs as if by accident. Beatrice would feel her own cunt clench, wetness soaking the crotch of her panties, and she would stay until Talia pulled on a sleep shirt and clicked off the lamp.

Gideon’s door was the same. He left it cracked while he stripped after work, kicking his jeans toward the hamper, standing in gray boxers that did nothing to hide the heavy shape of his cock. Beatrice had seen him tug those boxers down a hundred times. She had watched him scratch his stomach, yawn, walk naked toward his bathroom with that thick cock swaying. On shower nights she would wait until the water started and then ease closer. The bathroom door never quite latched. Steam rolled out. Through the gap she could see the fogged glass, the smear of his body, one hand braced on the tile while the other worked his cock with slow, unselfconscious strokes. He came with a low grunt she could hear even over the spray. Beatrice would press her thighs together in the hallway and sometimes, later, she would lie in her own bed and fuck herself with three fingers thinking about both of them at once.

She wanted them. Not in some vague, guilty way. She wanted Gideon’s cock in her mouth and Talia’s pussy on her tongue and she wanted to watch them do it to each other. The craving had grown teeth. It sat in her belly all day. She would catch herself staring at Talia’s mouth at breakfast, at the way Gideon’s shirt pulled across his chest, and she would have to leave the room.

That evening she did not even pretend to be passing through. Talia’s door stood open the width of a hand. Beatrice stopped. Talia was facing the mirror, already down to a black bra and matching panties, unhooking the bra with one practiced motion. Her breasts spilled free, nipples tight. She cupped them, looking at herself, and Beatrice’s breath snagged.

Behind her, Gideon’s bathroom door opened. He stepped into the hall with a towel around his hips, hair dripping, water running down the planes of his chest. He saw Beatrice standing there. He saw where she was looking. For a second nobody moved.

Talia turned. Her eyes went from Beatrice to her stepbrother and back. She did not cover herself.

“You’ve been doing that for months,” Talia said. Her voice was steady, almost curious. “Standing out there. I leave the door like that on purpose now.”

Gideon’s mouth tilted. He did not look embarrassed. The towel was slipping. “I thought I was imagining it. The way you look at us.” He let the towel drop. His cock was already half hard, thickening as Beatrice stared. “I jerk off thinking about you watching. About you coming in.”

Beatrice’s face burned. Her pulse was in her throat, her cunt. “I didn’t mean—”

“Yes you did,” Talia said. She hooked her thumbs in her panties and pushed them down, kicked them aside, and stood there naked, twenty-one and unafraid. “We’ve talked about it. About you. About what it would be like if you stopped hiding.” She glanced at Gideon. “We want it. Both of us. With each other, and with you. If that’s what you’re standing there for.”

Beatrice looked at them. Her stepson, dripping, cock rising. Her stepdaughter, bare, nipples dark, a gleam already between her thighs. The hallway felt too small. She could have walked away. She did not.

“Come here,” Beatrice said, and her voice came out lower than she expected. “Both of you. Talia’s room.”

They went. Talia sat on the edge of her bed, knees apart. Gideon stood beside her, cock fully hard now, thick, the head flushed. Beatrice shut the door and leaned against it for a second, taking them in, then she crossed the room and sat beside Talia.

“You two have never…?” she asked.

Talia shook her head. Color high on her cheeks, but her eyes were bright. “We’ve kissed. Once. We got scared. We didn’t know how to start.”

“I’ll show you.” Beatrice took Talia’s hand and placed it on Gideon’s cock. Talia’s fingers wrapped around him, tentative, and Gideon exhaled hard. “Like that. Firmer. Stroke him. Feel how he gets wet at the tip.” Talia did, sliding her fist, smearing the bead of fluid. Beatrice guided Gideon’s hand between Talia’s legs. “She’s already soaked. Feel that. Rub her clit with two fingers, slow circles. Don’t rush.”

Gideon’s fingers found her. Talia’s hips jerked. She made a small sound. Beatrice watched them learn each other, the way Talia’s thighs trembled, the way Gideon’s cock twitched in his stepsister’s grip. She put a hand on the back of Talia’s neck.

“Taste him,” Beatrice said. “Open your mouth. Lick the head first. Then take him as far as you can.”

Talia leaned in. Her tongue touched the underside of Gideon’s cock, then she closed her lips around him. Gideon groaned, his fingers still working Talia’s cunt. Beatrice stroked Talia’s hair, murmuring, telling her to use her tongue, to hollow her cheeks, to let him feel her throat. Talia bobbed, messy, spit shining on her chin. Then Beatrice eased her off and turned her toward Gideon’s face.

“Now you,” she told Gideon. “On your knees. Spread her. Look at her. I want you to lick her until she can’t talk.”

He dropped. Talia fell back on her elbows. Gideon put his mouth on her, clumsy at first, then hungrier when Beatrice told him where, told him to suck her clit, to push his tongue inside her. Talia’s hands fisted in the sheets. She came with a shocked cry, thighs clamping his head, and Beatrice felt a fierce, dirty pride.

“Good,” Beatrice whispered. “That’s how you take care of each other.”

She stood and stripped. Forty-two, her body still firm, breasts heavy, the trimmed hair between her legs already slick. She climbed onto the bed and pushed Gideon onto his back. His cock stood up, wet from Talia’s mouth. Beatrice straddled his hips and sank down on him in one slow, stretching slide. He filled her, thick enough to make her gasp. Talia watched, wide-eyed, touching herself.

“Sit on his face,” Beatrice said. “Face me. I want to see you.”

Talia swung a leg over Gideon’s head and lowered her cunt onto his mouth. He groaned into her. Beatrice rode him, grinding, her clit dragging against his pelvis, and she reached out and pulled Talia in by the back of the neck and kissed her. Talia’s mouth was sweet and startled and then hungry. They kissed while Beatrice fucked herself on Gideon’s cock and Talia rocked on his tongue. Beatrice could feel him throbbing inside her. Talia broke the kiss to moan, forehead against Beatrice’s, and Beatrice sucked on her stepdaughter’s nipple until Talia came again, shaking, flooding Gideon’s chin.

Beatrice lifted off him before he could finish. She wanted more. She wanted to teach them everything.

“On your hands and knees,” she told Talia. Talia obeyed, ass up, pussy glistening. Beatrice lay on her back beneath her, pulled Talia’s hips down, and put her mouth on her stepdaughter’s cunt. She licked her open, slow, thorough, tasting Gideon’s spit and Talia’s come. Behind her she felt Gideon’s hands on her hips, then the blunt press of his cock, and he shoved into her from behind in one deep thrust that knocked the breath out of her. She moaned into Talia. Gideon fucked her hard, the way she had imagined in the hallway, slapping against her ass, and Beatrice ate Talia with greedy strokes of her tongue, two fingers pumping into her, until Talia came on her face with a broken, grateful sound.

They rearranged without being told. Beatrice on her back now, in the middle of the bed. Gideon between her thighs. He pushed into her in missionary, folding her legs back, and Talia knelt beside them, kissing Beatrice’s mouth, pinching her nipples, whispering filthy little praises. Gideon drove into her, deep, relentless, and Beatrice came around his cock with a cry she did not recognize as her own. He pulled out, panting, still hard. Talia took his place. They had no cock of her own, but Beatrice had taught her fingers, and Talia pushed three into Beatrice’s stretched, dripping cunt and fucked her with her hand while Gideon knelt at Beatrice’s head and fed her his cock. Beatrice sucked him, tasting herself. Then they switched again. Gideon back inside her, Talia’s mouth on Beatrice’s breasts, then lower, licking where Gideon’s cock stretched her, and Beatrice came again, and again, until she was shaking and wet to the sheets.

“Your turn,” she rasped at Gideon, and he thrust twice more and spilled inside her with a groan, hips stuttering. Talia climbed up and sat on Beatrice’s face and Beatrice licked her through one last orgasm, Talia’s thighs trembling around her ears, Gideon still buried in her, softening.

They collapsed. Beatrice in the middle, Gideon on one side, Talia on the other. The room smelled of sex and steam and skin. Beatrice stroked Talia’s hip, Gideon’s chest, her body still pulsing. She felt used in the best way, glowing, emptied out.

“This can be every night,” she whispered. “Whenever you want. I’ll teach you anything. We don’t have to hide. We can just… have this.”

Talia made a small, sated sound and tucked closer. Gideon’s hand rested on Beatrice’s stomach. For a long minute it was perfect.

Then the quiet got into her.

Beatrice stared at the ceiling. The afterglow was still there, the wetness between her legs, their heat against her sides. But something cold moved under it. She thought about the hallway, about a year of watching them when they thought they were alone, about the way she had stood in the dark and taken from them without asking until they caught her. They had said yes. They had wanted it. She had heard them say it. Still, lying there with her stepson’s come leaking out of her and her stepdaughter’s taste in her mouth, she could not tell if she had taught them something generous or if she had simply pulled them into a hunger that would not stay contained in this room. Talia’s breathing evened toward sleep. Gideon’s fingers twitched on her skin. Beatrice kept stroking them, tender, automatic, and wondered, with a thin, late doubt she could not quite swallow, whether she would still want to look them in the eye in the morning.
