"We can't get them off her legs," Billy said. "Cut them off like we did this morning."
Billy left to get a knife. Lynn thought if she was alone with Tony, she could talk at least one of her stepsons out of this wicked thing they were doing with her.
"Tony, why are you doing this?" she asked. "It's wrong you know. Why are you humiliating me, cutting my clothes off and tying me up like this? I haven't done anything to you boys, have I?"
"You better shut up," Tony said. He gripped his stepmother's ass, squeezing and feeling, fondling the creamy, smooth swells of her ass. "Billy said if you tried to stop us, we'd have to keep you tied up all day and night. And you better not tell Dad, or we'll make it real hard on you."
"Oh, God!" Lynn moaned, knowing she couldn't talk Tony out of it. Her body trembled, the cheeks of her ass tightening involuntarily.
"I've got the knife," Billy said. "Take your hands out of her panties. I don't wanna cut you by accident."
Lynn felt the knife sawing at her panties, then they fell to the floor between her spread legs. She was naked from the waist down, and her face was flaming with shame as they looked her firm ass over.
"That gives me a fucking hard-on," Billy said. "Hey, Lynn, you ever let Dad assfuck you?" He giggled lewdly. "I bet you really go for a cock up your pretty ass, don't you?"
Lynn could not reply, her throat was constricted and dry. She felt their hands caressing her naked ass. Her body twitched spastically, jerking, as she tried to pull away from them.
"Wanna see her asshole, Tony?"
"Yeah, let's take a look at her asshole," Tony said. "I heard you can tell if a girl takes it up the ass by looking at her asshole."
"Yeah, I heard that, too."
Lynn felt the cheeks of her ass being parted, and she clenched them tightly, but it did no good. Tony pulled one asscheek and his brother the other. They exposed her asshole, squatting behind her and peering at it.
"Still looks tight to me," Billy said.
"See if you can stick your finger in her ass, Billy."
"Please, don't!" Lynn groaned, her asshole becoming very tight against the invasion. "I've never… never done anything like that before. It's horrible… shameful! Please, don't do this to me!"
"Shut your fucking mouth, Lynn!" Billy growled as he started poking his finger against her asshole.
Feeling the pressure against her asshole, Lynn held her breath, steeling herself for the expectant pain when he shoved his finger into her ass. The pressure grew as Billy pressed the tip of his finger harder.
"Ohhh!" Lynn moaned as Billy's finger penetrated her virgin asshole. "Take it out! Oh, God… take it out!"
"She's kinda tight," Billy said, ignoring his stepmother's plead. "I don't know, Tony. Maybe she hasn't had a cock up her ass!"
Billy worked his finger in and out of Lynn's asshole, fucking slowly. She could hear her stepsons gasping and panting in their perverse pleasure. She refused to acknowledge the swelling of her clitoris, or the moistening of her cunt. She wiggled her naked ass around, trying to dislodge Billy's finger. All her wiggling did was excite the boys, making Billy fuck his finger faster into her ass. She was surprised to find it no longer hurt. The slight burning sensation even felt somewhat pleasant to her.
"She likes it!" Tony said, half giggling. "Look at her shake her ass, Billy! I think Lynn goes for assfucking, don't you?"
"Sure looks like it," Billy replied, thrusting his finger deeply into Lynn's asshole, wiggling it about.
"My cock is gonna explode," Tony said in a husky voice. "I gotta get it out of my pants."
"So take it out," Billy said, more interested in watching his finger sink deeply into his stepmother's asshole. Her asshole gripped his finger, the tissues sucking on it as he pulled back, then sinking inward with his finger. "I think our loving stepmother would love a cock in her hot asshole, Tony. She's sure tight, and it feels like she ain't gonna turn my finger loose."
Tony had jerked his throbbing cock from his pants, squeezing it in his fist, watching Billy fingerfuck Lynn's ass.
Lynn's ass twisted in an effort to dislodge Billy's finger, but the more she twisted, the faster he fucked her asshole. Realizing she was providing them with erotic excitement by her movements, she held her body stiff and still. Even that did her no good; Billy fucked her ass just the same.
She slumped, held upright by her straining arms. The sobbing sounds she made were soft, almost inaudible. Her shame was intense, her hopeless position frightening her more than anything she had ever felt. Her tits were uplifted by her raised arms, and shame flooded her when she felt her nipples swell, tingling as they pressed into the cups of her bra. She could no longer ignore the sensitive pulsations of her cunt and clit. Something exciting seemed to happen as Billy rammed his finger in and out of her asshole, becoming more brutal. Trying to control her fast breathing, Lynn gasped softly. Her ass was writhing slowly. The pleasant feeling, starting in her asshole, was creating a warmth in her thighs, her cunt and her tits.
No, I don't want this, she screamed in her mind. I can't stand it! Ooooh, please, please. What's happening to me? Why does this feel good? Why does it feel like I'm going to come? This is insane… I can't come! Not this way, not with a finger up my ass! I can't! I just can't!
"Ohhhh, I don't want to…" Lynn groaned, then her cunt exploded.
The convulsions of her climax sent heat waves up and down her body. Her cunt lips moistened, her clit throbbing sweetly. Her asshole sucked on Billy's finger. She moaned loudly in agonized ecstasy. Her ass twisted, grinding and going through a series of bumps like some stripteaser on a well-lit stage.
"Hey, I think I made Lynn come!" Billy gurgled. "I think she's coming, Tony!"
"How can you tell?" Tony asked, driving his fist back and forth on his cock.
"Her asshole won't turn my fucking finger loose? I think Lynn is cuming. Feel her cuming."
Tony slipped his free hand up his step-mother's thigh. He cupped her hairy cunt, feeling it oozing with wetness. Experimentally, he worked his middle finger into her pussy.
"Oh, don't!" Lynn groaned. "Don't do that to it! Not there! It's wrong, Tony!"
Tony was awed by the heat surrounding his finger, the wetness and how easy he could shove his finger into her cunt. Lynn's cunt was convulsing about his finger as her orgasm drew on and on.
"I think you're right, Billy," Tony said. "I think you made her come." Lynn's orgasms slowly receded, but when Tony pulled his finger out of her cunt, with Billy taking his out of her asshole, Lynn felt herself come again, although it was a mild orgasm and nothing like the boiling one earlier.
The boys stood behind her, looking at her naked ass and thighs.
"I think Lynn is bullshitting," Billy said. "I think she likes being tied up."
"Sure looks like it, Billy. Do you think she and Dad do it this way?"
"Maybe," Billy replied. "But I can't see Dad being that brave with a woman."
Tony's, cock continued to throb outside of his pants. He was standing close to his stepmother, and he began to rub the seeping head of his cock against her thigh, then over the cheek of her ass.
"What are you up to, Tony?" Billy asked.
"Nothing, just rubbing my cock on her, that's all."
They talked about her as if she wasn't there. Lynn's embarrassment was more pronounced because of it. She was just a plaything for them.
"Let's piss on her fucking ass," Billy said. "Oh, no!" Lynn screamed. "Don't make me ashamed any more! Don't do it, please!"
"I can't piss with a fucking hard-on," Tony said.
"Then I'll do it!" Billy replied, taking his cock out of his pants. His prick was half hard. He shoved it up to his stepmother's creamy naked ass, sliding it into the hot crack between her cheeks.
