Help out as best you can
From Torg Adventure
Ashley hands you a pair of handcuffs and a rope, saying in a authoritarian voice, "Cuff her and tie them to the bedposts."
You never seen Ashley in this mood before -- more determined and in control. You start by putting a cuff around Heather's wrist. She gasps. You can tell she likes this, and that it arouses her. She lays with her arms outstretch in front of her. You put the other cuff on, getting another excited gasp. As you uncoil the rope, a length of it drags across Heather's arm. A shudder runs through her. She's really getting off on even just the touch of the rope and cuffs.
You look over to Ashley and see her tying rope around her sister's legs. She has a look of intense focus on what she's doing. The rope on Heather's naked body looks very hot. You get back to your task.
Those three years you spent in Boy Scouts when you were young come back to you. You tie the middle of the rope around the chain of the handcuffs. Then you tie one end around one bedpost and use a knot you learned for putting up tents that can be adjusted and tightened. Then you tie the other end of the rope to the other bedpost with the same knot. When the rope drags across Heather's wrists, she gasps a little. You tighten the ropes and pull her arms in front of her. By the time you're done, Ashley has tied her sister's legs in a way that makes it so Heather can't get out of the doggie-style position she's in. It looks beautiful. Ashley stops, checks your knots and how tight the ropes are, and smiles up at you with a mischievous look in her eye.
"Good work, darling. Have you rigged before, or are you just a natural?" she asks.
"I was in Boy Scouts, though we never used it on girls. That wasn't in the manual," you chuckle.
"Well, because you helped tie her up, you get to help me take out some of my frustrations on her." She grabs a vibrator and the strap-on dildo that Heather used last night. Handing you the vibrator, she says, "Here, put that in her kitty."
It's a pretty big, curved purple vibrator with three speed settings. You've never used toys on Ashley. Last night was the first time you've really seen any used at all. You put it on the lowest speed and slide it along Heather's slit and clit.
"Aaaa-aaah!" she cries.
"Too loud," your girlfriend announces. She gets a ball gag out of the drawer.
