Boyfriend just might have altered the size of his cock

Oh crap, what does that text mean? Is this going to get crazier or worse somehow? And just like that I got my first answer. My boyfriend kept sliding into me till finally he bottomed out at his 8 inch mark where I've become accustomed to his assaults. However, somehow it didn't stop there. His cock kept going like he grew a couple more inches.

"Have you guessed your next surprise?" Text received from boyfriend

At this point I was begging him to stop "I'm in fucking class. I can't take this right now. I'm already starting to moan and turn bright red. People are starting to look."

But it just kept on going deeper and deeper. Until finally it hit a wall and it seemed like it could go no further. His cock is definitely two or three inches deeper right now than normal. What the heck is going on?

"Oh fuck your boy pussy feels even tighter than usual lol I wonder why. But wait a second I'm stuck. Why can't I go any further? Let me try punching it through a few times to get a little deeper hahaha." Text received from boyfriend

Did you just say deeper there's more how much more cock is there? I had to grab hold of the desk white knuckles in order not to make any noise. But he continued a very hard punch fucking that started to tenderize my prized little hole.

After a good 20 minutes of his jackhammering something finally loosened up and he was able to push even further in. It felt like he was pushing through my stomach. I could feel the bulge just under my t-shirt. This definitely wasn't his cock this one was much bigger.

"Since you don't seem like you want to play the game and guess the surprise I might as well just tell you. I got that extension device that you pull over your dick to make it bigger. Hope you don't mind if I got their biggest model. It almost doubles my length and the fun part is I can set the girth with just a flick of a switch. I figured I'd start you at my normal girth so they're not too many surprises all at once lol might as well just sit back and enjoy. Oh and try not to draw too much attention to yourself" Text received from boyfriend

Shit I'm totally screwed I can't just get up and remove the panties or else people will find out what's happening. I'm just going to have to grip down and take it. Till he or the class finishes.
