Cumming won’t be so easy

You feel the world spin, assuming the tentacles have lifted and spun you head down as they hold and spread your limbs and torso tight. This was followed by the beginning of intrusions, a small squirming pushing first up to then past your hole. You whimper as it fills you, which leaves your mouth opened just enough for another tentacle to come from below and push in, forcing your head to bend back as it straightens to your throat. You’re left spit roasted upside down, both pulsing and thrusting their tendrils violently into you.

This feels amazing, such overwhelming sensations while feeling massively used and vulnerable. When another set of tentacles choose to encircle and stroke your dick, you feel like you’ll instantly explode. That is... until a small tentacle slithers into the tip of your dick. The sounding is too much, and you’re body tries to cum, but can’t. You squirm and thrash, but nothing, you physically can’t cum! Whimpering in panicked need, you’re mind starts to go blank in desire. You continue to get fucked thought, your body attempting and failing to cum again and again.
