You try to withdraw

There's no way you'll let this old fatso take your virginity. There's no way out of his campervan, but through the door behind him. He's already so close to you that you're not sure if you can make it, but you got to try.

"I'm sorry, but...", you start. You don't even get a change to finish your sentence, before you feel Marvin's big hand pushing you back towards the bed. His movement is so sudden that it takes you by surprise. You definitely didn't expect him to be so fast.

"Oh no, you're not going anywhere yet", he says, while flipping you around to your stomach and pinning your hands behind your back. You feel some kind of a rope tightening around your wrists. How did he find that rope so fast? You realize that this must have been his plan all along.

"I know you want it, so don't try to act otherwise", you hear him saying. While still holding you against the bed, you feel him yanking your shorts off, revealing your naked butt to him. "Mmm, what we have here... I'll sure love break that in...", you hear Marvin saying.

Soon enough you can already feel cold lube pouring on your ass, soon followed by his finger, forcing its way into you. You try to squirm, but with no effect. Ropes are holding your wrists tight together and his other hand pressing you against the mattress keeps you from moving an inch. All of a sudden you feel how his rock hard, massive cock presses against your virgin asshole.

"Please don't, I can't", you plead once more, as he starts to push his cock against your tight hole. At first it feels like there's no way it would fit into you, but then, slowly and surely, you start to feel how his dick keeps pushing deeper and deeper into your ass.

"Ooh, I can't...", you moan, as his cock painfully drills deeper into your ass. "...take it. Please...", you try to continue, but the overload of sensations makes it hard for you to speak. It feels almost like it'd never end, until suddenly you feel Marvin's balls against your ass cheeks. You can feel his fat cock stretching your tight ass from inside out.

"Isn't this what you came here for?", you hear Marvin panting, "Didn't you wanna get real dick?". You could have never imagined that this was really how you'd lose your virginity.

With his fat cock still deep in your ass, you can feel Marvin taking a better position on top of you, and soon enough his hard cock starts to pump back and forth in your ass. With each push you feel pain, but with each push the pain becomes more bearable.

"Mhm, you like it slut?", he keeps asking, "You like how I stretch your virgin ass?"

You try answering, but end up only panting against the mattress. With each question and mumbled answer, Marvin keeps adding pace and **** of his pushes. Eventually you find yourself pinned tightly between Marvin and the mattress of the bed, with his dick beating your ass like a sewing machine. To your own terror, you notice your own dick getting hard. Are you liking this!?

"I'm coming", Marvin announces suddenly and without any further warning, you can feel his sperm filling your ass. You feel Marvin's heavy body resting on top of you, as his cock releases the last drops of cum. Once his cock stops twitching, Marvin rolls over to your side, releasing you from under him.

Still tied up, you take a moment to just gather yourself. Your ass feels sore and you can feel Marvin's sperm leaking out of you. You roll over, sit up and take a look around. To your surprise, you see that Marvin has already fallen asleep. "Oh great", you think to yourself, your hands still tied tight, "How the fuck I'm now going to get out of here?".

What do you do? Wake up Marvin or just wait until he wakes up? Or do you try to escape now?
