Lean further

Matt's knees took his weight as he knelt on the bed between his twin sister's legs, the tip of his cock replacing his exploring fingers between Lily's labia. She lay back, welcoming her brother on top of her as his cock slid inside the warm, wet tunnel of Lily's pussy.

"God, Matt, you are bigger than dad," Lily gasped, her legs going behind Matt's ass, pulling him deeper. He put his elbows on either side of his sister's head, moving his hips instinctively, guided by her legs.

Matt thrust with an almost **** necessity, trying to get as deep inside Lily as he possibly could, as fast as he possibly could, bouncing his sister's ass on the bed. "Ssshhh," she hissed, looking toward the closed door. "I don't want to even think of what dad would do if he caught us," she panted between thrusts.

He didn't slow his thrusts, however he did try and muffle his own groans of pleasure. One hand lifted off the bed, sliding down Lily's arm and across, cupping over her modest breast, feeling the hard button of her nipple.

Almost at that small touch, already near the edge of another orgasm after their dad had filled her, Lily arched her back, her pussy clenching around Matt's cock. He bit his lip, trying as hard as he could to stay silent as he started cumming as well, spurt after spurt of cum washing into his sister's pussy.

The twins lay there, shuddering in their embrace, Matt now laying on top of her, feeling her firm breasts pressing against his chest, her ankles locked behind him, holding him inside her.

Finally, the euphoria ebbed, and Lily stirred underneath Matt. "You should get cleaned up before supper," she murmured, pushing him up gently.

"What about you?"

Lily shook her head. "Dad likes it when I go to supper with his spunk inside me - something about having mom and me at the table together."

"Can we... I mean, will we be able to..."

"We'll see," Lily cut him off. "No promises, okay?"

Matt nodded mutely as he gathered his clothes and snuck back to his room. He had lost his virginity to his sister, and that was without using his power, and he wondered how the power would have changed things. Maybe he would find out later.
