Cum immediately

You and your dad both screamed in pleasure as the head of your dick entered his tight hole. Unfortunately, you were both immediately overcome with the feeling. You didn't even get another inch forward before you felt yourself cum a fuck ton into your Dad's ass. Any embarrassment of a premature ejaculation wasn't on your mind, as you allowed for the orgasm to ride your entire body.

You weren't the only one who couldn't hold out either. Your dad, who was moaning like a bitch in heat, was currently painting himself in white. His cock spasmed as it unloaded his baby batter from the mere penetration of his backdoor.

Once the two of you came down from your cum, you collapsed onto the bed. Your dad leant in and the two of you began to lazily make out, bathing in your own semen. You pulled off of him to apologise.

"Sorry I finished so quickly." you say sheepishly, "That's never happened before."

"Son," your Dad grinned, tugging on your dick, "I did the same thing. We've got plenty of time to last the night. Though I think you're ready now."

There was no denying that your cock was still rock hard, despite having just cum. Your dad was staring at you lustfully, obviously having the same naughty thoughts as you.
