Give in

There's no point in fighting. You cum.

Mentally gritting your teeth -- you can't do so physically -- you keep dragging, sobbing at the persistent rubbing on your sensitive clit and your squeezed breasts swelling with blood. Still sensitive from the first orgasm, you come again. Then, steps later, again.

It's not long before you collapse to your knees, breathing heavily. Blinking tears from your eyes, you look up to see Krik watching you, looking amused.

"Taking a little break are we, Dreg?" they ask. "You know, I feel like a little break, too. Let's deal with that problem of yours, huh?" They unclip the clamps from your breasts, leaving dark bruises behind, and produce a small pair of scissors and cut away the cords between your legs, freeing your clit and giving Krik full access to your cunt. From behind, they grab your hips and lift, impaling you on their cock, and start to thrust.

Your cunt might be free, but the rest of you is still tied. Your shoulders are wrenched back by the crate you're still bound to every time Krik thrusts your unprotected face and tits against the floor. Said tits are becoming more and more sensitive as every thrust tightens the rope looped around them. The cold steel floor chafes your nipples.

Eventually, Krik pulls out and comes on your back. "That's enough work for today, don't you think? You just rest here. Someone will come find you if you're needed. Oh... I guess I should clean up, huh?" Krik stands over you, and a torrent of piss washes down your body and onto the floor. "There you go, all clean. Later, Dreg."

And then you're alone, lying trussed up in a puddle of alien piss and semen.
