"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.
