HardTied - Mia Gold - X Marks The Spot (2023/HD/1019 MB)

Lashed to a chair, stripped and spread wide, she squirms and strains against her bonds.
Her pussy has been worked over well, teased, denied and edged repeatedly.
A cloth and tape gag seals her mouth shut and metal nose hooks distort her face and pull it taught.
Horny and desperate to cum, she's willing to try anything for relief. She arches her back, straining her neck and thighs against the ropes.
In sheer frustration, she humps the dildo positioned between her thighs, trying in vain to bury it deeper into her cunt, in hopes it will be enough to flip her switch.
Even her thumbs are tied and she finds no amount of struggling will help.
It doesn't take long for her to learn to beg.

A bigger dildo, a smaller girl, and a brand new battle! Sweetie Plum takes on the Spring Loaded Blowjob Trainer today, and it is an epic fight. At first, she is strong enough to pull back all the way, giving her a chance to swallow and breathe. But then her hands are locked behind her back and the spring attachment point is moved back. Now Sweetie is in trouble. As she gets more and more tired, she can't pull back so hard anymore and the dildo shoves deep into her throat every time she lets go. At the end, I saved her when she lost the battle and got stuck. Poor Sweetie!
