Lily looked around her room, her eyes avoiding his gaze as he let go of the door handle. "Do we really have to do this, dad?" she asked in a small voice.

The answer floated into Matt's mind as he stood there in their dad's body. "Yes, we have to. Why don't you get into position." He watched as his twin sister turned her back to him, walking slowly to the foot of her bed and bending down, putting her hands on the mattress. Matt's cock throbbed in his pants as he saw Lily's ass exposed, and he stepped forward, hands automatically going to the buttons on his shirt. "You look so beautiful," he murmured as his shirt fell to the floor, his hands working swiftly on his pants, which joined the shirt on the floor.

Matt reached his hand out, resting on Lily's hip, his other hand sliding across her ass and down between her legs, fingers easily finding the smooth skin of her shaved pussy. He could feel the heat pouring out of her body as he pushed his fingertips between her labia. As he did, Lily's trembling arms gave way, her head and upper torso laying on the bed. This may have been an involuntary movement, but Matt found the new position better, Lily's pussy more accessible to his fingers.

And to other things as well. He took another step forward, the fingers sliding between her labia moving to the shaft of his cock as the tip brushed against her upturned ass. Matt bent his knees, lowering himself until his cock was pressing against her pussy instead of her ass, his hand moving the tip up and down her slit. With each motion, he pressed a bit harder, watching the tip disappear inside her flesh. Then his cock found its way to deeper flesh, and Matt pushed harder, half his cock sinking into Lily with one thrust.

Lily grunted as she felt the penetration, her hands curling into the comforter as Matt's hand moved from his cock to her hip, both hands now on the soft flesh over her hip bones as he drove his hips forward. Lily grunted again as she felt her dad's cock fully inside her, and didn't relax as Matt pulled his hips back, knowing the movement was only a step in the entire dance.

Matt lost all track of time. He could have fucked her for seconds, or hours, although he would have guessed it was somewhere between the two extremes. His hands held her tight, his hips moved fast, the sensations of his sister's tight pussy clenching against his cock more intense than anything he had ever felt. The only sounds in the room were his hips slapping against her ass, and the grunts Lily made every time Matt thrust forward. Then he felt his orgasm approach, one that he had experienced before, but at an intensity that dwarfed every masturbation session he had ever had. He instinctively drove his hips forward as hard as he could, hands tightening on Lily's hips as his cock spasmed inside her, causing her to groan instead of grunt as she felt her dad's cum filling her up.

"Oh, god," Matt groaned, his weight pressing Lily's thighs against the edge of the bed, his knees trembling with the **** of his orgasm. He held his cock deep inside her until long after his orgasm ebbed, not pulling out until most of his cock had slipped free naturally, only the head staying inside her body. As he pulled his hips back, he saw a strand of cum stretch between his cock and her pussy before snapping free.

Matt stroked Lily's ass, hips, and finally circled around to her stomach, pulling her to a standing position in front of him. He pushed his wet cock against her lower back, his hands sliding from her stomach to cup over her breasts, squeezing them as he hugged her against him. "Damn, that felt good," he breathed.

"We shouldn't be doing that," Lily said, her sad face looking over her shoulder. Matt could tell she just wanted to move away from him, but he wasn't ready to do so. He leaned forward, pressing his mouth on hers, his hands still molesting her breasts as he pushed his tongue into her mouth, swirling it against her tongue. She allowed it, but her tongue barely moved against his.

Matt broke the kiss, looking at his sister's somber face through their dad's eyes. "I can't wait until Helen gets called in again."

Lily winced at his words, and Matt jumped back into his body, leaving their dad with his hands on her breasts and his cum covered cock pressing against her back. He lay in the dark, realizing how much fun he could have with this ability. As he lay there, he heard the water running in the bathroom separating his room from hers, and realized Lily must be cleaning their dad's cum off herself.

Matt was still smiling as drifted off to sleep.
