Tek likes the lack of words. It leaves room for things like grateful, open-mouthed growling when he's being shoved down and bodily pressed up against.

The way that Robin pins him there, though--that is what he likes the best. He loves the rush of surprise when pushing back doesn't actually get him anywhere. Here, he's with someone who even can hold him down. Half of his struggling is just for the fun of testing it.

However, the other half of the struggle actually does have a point. While he's busy ecstatically writhing under the teeth at his neck, he can easily kick off his boots without distracting anything... but, anything more than that is going to require significant effort.

So, he does fight. He shoves back against Robin's more-than-human strength, and mostly only succeeds in rolling against his partner's body in a way that really isn't going to help his case, at first. It takes him a few attempts until he can bully himself enough room to finally be able to reach down between the two of them and hurriedly claw at waistbands and fasteners--trying to get clothing at least halfway out of the way before Robin can just go ahead and finish without him.

If any buttons are ripped off or zippers broken, he really can't be held accountable.
