She doesn't

Valk slowly strokes Maud's cock, covering it with her juices and Maud's precum, as soon as it's sufficiently lubbed Valk pushes it into her pussy.

Valk slowly rides the ten inches long cock as her own 12 inches long bitchbreaker of a cock flops and slaps Maud's torso, slowly covering the mare in precum.

Maud tries to thrust into the tight pussy around her cock, but is too well tied up in bondage for it, meanwhile Valk is savoring the slow ride, taking her time to build up a massive orgasm as she deliberately only takes a few of Maud's inches into herself.

As Valk gets to the edge of her orgasm she takes a breath and slams down all the way to the base of Maud's cock, that triggers her orgasm, her pussy ripples and grips even tighter onto the cock.

Unbeknownst to Valk, Maud hadn't taken the threat of punishment seriously, so ever since the start she hadn't even tried to fight off the pleasure coursing through her new appendage, with her deadpan face it was even harder to tell that Maud was about to cum when Valk suddenly took all of her in one movement, the orgasm was fast and since it was inside Valk one hundred percent noticeable.
