I like my bonds to me make-shift and adaptable; if the victim is wearing jeans then simply pulling them down around her ankles and leaving her shoes on can pretty much immobilise those pesky kicking legs. Likewise, her blouse or shirt can be used to tie her arms, and belts are good for this too. Make sure to tie the arms back just above the elbow though as wrist binds can be wriggled out of, especially if you're not great with knots. For a gag why not just stuff her slutty little panties into her mouth? Wrap a length of torn clothing around her head to keep them in or use some duct tape.
Personally I love the classics: just holding her arms behind her back with a hand strongly held over her mouth. With your body weight on top of hers you're pretty much free to thrust savagely into her without remorse. You can't squeeze her tits in that position though which is a shame. As a duct tape fan I'm also fond of restraining a girl at the elbows, knees, wrists and ankles with a good roll of the ol' black and nasty. You get to laugh your tits off watching them helplessly fish-flop around before you pound them like last weeks beef.
Number one on my restraining sluts hit parade though requires my lovely bed with metal bars on the head board. I have a kinky pair of leather wrist restraints similar to handcuffs and those restrain her hands above her head to the metalwork. With her on her back her ankles are then bound to either side of the head board using lengths of silk. She's now entirely exposed and at your mercy (not that you'll giver her any). Pick a hole... Any hole, this whore is yours for as long as you want her, JUST ENJOY YOURSELF! lol
