keep going

"I've seen how much of a cock tease she's been, and maybe it wouldn't be the worst thing in the world for her to find out what happens when she teases."

Alex looked up at her dad in shock, not believing that he could take his side, let alone let him continue. Dylan stepped forward, reaching down and pulling Alex up by the hair, pushing her toward the bed, making her bend at the waist, face first on the bed, her ass exposed to the two men.

"Please," she begged, but neither said a word as Dylan took his place behind her, and without ceremony, shoved his cock through her hymen and deep into her pussy. She screamed in pain, and Phil felt a throb of guilt that couldn't compare to the throb of lust at watching his daughter get deflowered. Dylan gripped her hips and thrust again and again, jarring her body forward, her thighs against the bed as he used her for his pleasure.

Then Dylan pulled out, apparently ready to cum, but Phil spoke up. "No, cum inside her - you wanted to fuck her, so fuck her."

Dylan grinned. "Haley's never let me cum inside her," he said, and shoved his cock back into Alex, despite the renewed cry from the girl. Two pumps later, and he pushed as hard as he could, trembling all over as his orgasm hit, his cock filling his girlfriend's sister with sperm.

Alex could only lay there sobbing, not wanting to believe this was actually happening, and with her dad's permission. Then Dylan pulled out, cum still dripping from the end of his cock and starting to drip from Alex's pussy. She stayed bent over the bed, weak from sobbing, and partly from shock, as Dylan dressed and almost sheepishly left the room.

Phil stepped forward, licking his lips, and coming to a decision.
