So, did you petrolheads learn something new?
On the Hood
If there's anything better than sex in the car, it's sex on the car. If you're in the mood for some open air action, or want to put on a show for the rest of the folks in the parking garage, study these sex positions, lay your honey across the hood and start your engines.
A classic car Kama Sutra pose. The woman sits on the hood, wraps her legs around the man's waist and supports herself with her arms, leaning back. She can control the motion by thrusting with her pelvis, or pulling him towards her with her legs. She may also brace her feet on the car bumper on either side of him for better leverage
The Bridge
The woman lays back on the hood with the man standing in front of her between her legs. She lifts her legs so that she can hook the back of her heels over her partner's shoulders. The woman then tilts her pelvis up to straighten her back, lining her crotch up with the thrusting of his cock. The man can support her lower back with his hands, and lean back slightly. The woman can vary the angle of her pelvis for better G-spot or clitoral stimulation. This position allows for deep penetration and will make you both feel like porn stars.
The Wheelbarrow
This one is a bit acrobatic and requires some upper body strength from both partners. The woman lays her upper body face down on the car hood or trunk. The man lifts her legs up and holds them spread apart as he fucks her from behind. The woman can also wrap her legs around the man's waist (crossing her ankles behind her back) for extra support. This positions gives the man a nice view of his partner's backside, and is good for G-spot stimulation.
Over the Top
For when you really want to put on a show. The woman climbs up on top of the hood on all fours, with her rear facing the front of the car. She leans on the roof of the car to support her upper body. The man kneels on the hood behind her and fucks her doggy style. Take care not to break the windscreen, and don't bounce too hard or you may lose your balance.
In the Backseat
Sex in the back seat is cozy and comfortable - or maybe just cozy, depending on how small your car is. At any rate, the backseat offers you room to stretch out and steam up the windows.
Simultaneous oral sex. Both partners lay across the backseat, the woman on the bottom with legs spread and the man on all fours over her in the 69 position. He eats her out while she sucks him off. We recommend that you lay down a towel first, or keep some tissues handy as this can get messy.
Up and At 'Em
Woman lays across the back seat with the man on top between her legs. She brings her knees up toward her chest. He kneels between her legs and pulls her pelvis up toward his. The woman can plant her feet on the interior of the car and use her legs to pump her pelvis. Alternately, if there is room, she can hook her legs over his shoulders. This position allows for really deep penetration, so go easy at first.
Cowgirl
The man lays across the back seat and the woman kneels straddling him. She should lean forward to avoid bumping her head on the roof as she rides his cock. This also allows her to vary the angle of penetration for better clitoral and G-spot stimulation.
In the Front Seat
Getting in Position: Depending on the amount of head and leg room in your car, and whether it is a standard or automatic transmission (stick shift or not), it may be difficult for one partner to climb across the front seat to the other side of the car. In these cases, one person may actually have to get out of the car and enter the other side, then close the door once the partners are in position.
Classic
The missionary position of motoring. The woman is in the passenger seat, which is reclined as far as possible. The man gets on top of her, with his feet on floorboards, between her spread legs. The woman may have her feet on the floorboards, or if there is room, raise her knees and rest her feet on the dash.
Straddle
This time he reclines in the passenger seat, with her on top astride. The woman controls the action as she rides his cock. Good position for cars with less leg and head room, but she needs to take care not to disengage the parking brake with her knee.
While Driving
NOTE: These illustrations were performed by professional cartoon stunt drivers on a closed course. These positions are unsafe at any speed. We can't advocate engaging in sex acts while operating a moving vehicle.
Sit on My Lap
Let her do the driving. You may need to move the seat back or adjust the steering column to make room. The male partner operates the foot pedals and shifts, while the woman takes the wheel. If she leans forward slightly, she can grind into his lap, but take care not to lay on the horn or deploy the air bags.
Face to Face
Again the woman is seated on top, but this time facing her partner. Although this position is very romantic and lends itself to hugging, caressing, deep kissing and longing gazes, we strongly advise you keep both hands on the wheel and your eyes on the road if your vehicle is in gear.
Reach Over
This is the basic front seat blowjob. The woman leans across from the passenger side and sucks the man. In most cases, both partners can keep their seatbelts on, making this a safer on-road position. It's also more discreet, since the woman is out of sight, but don't be surprised if you get the thumbs-up from big-rig truckers.
Half and Half
Car sex can be creative. Use your imagination and don't be afraid to think outside the car.
Front and Center
This one's a little tricky; it's sort of like a carseat glory hole. The man kneels on the front seats facing the back seat of the car, straddling the gear shift and parking brake. He sticks his erect cock through the space between the seats. The woman sits in the back seat and blows him. If there's enough clearance between the seats, she can try backing her ass up to the gap so he can fuck her doggy style.
Open Door
With the door open, either the man or woman sits in the car seat, facing outward. Their partner kneels outside the car between their spread legs and goes down on them. If caught in the act, you can pretend you were looking for a lost set of keys.
Sex on a Motorcycle
Let Her Drive
The guy takes the passenger seat behind the woman as she leans forward onto the handlebars to expose her coochie. If the bike has a sissy bar, he can lean backward onto it while tilting his pelvis up. Otherwise, he may need to grip the sides of the seat to get leverage for thrusting. She can also ride him by bracing her feet on the pegs and moving either back and forth or up and down. This position is good for a controlled fuck - just make sure she doesn't give it too much throttle when she gets turned on.
Face to Face
The guy seats himself on the motorcycle as usual, and the woman mounts him by sitting on his lap so they are face to face. She will need to wrap her arms around him and hold tight to maintain balance. If she has rear foot pegs to brace against, the woman can control the depth and speed of penetration by riding the man's cock and bouncing up and down on it. You don't want to bounce too much, though, or you'll wear out the shocks - or fall off the bike. This is the best position for the guy if he wants to actually see where he's going.
Up the Tailpipe
This stationary position utilizes almost the entire length of the motorcycle. The easiest way to get into this position is for the woman to seat herself on the bike and lean forward so she is grasping the handlebars. If the bike is too long, or she's too short, she can wrap her arms around the gas tank. The man, standing behind the bike, reaches on either side, picks up her legs, and extends them backward over the end of the motorcycle. As he supports her back end by holding her legs up wheelbarrow style, he fucks her from behind.
This position can be a big turn on for both male and female motorcycle enthusiasts. The woman will get off from having almost full body contact with the bike and having her face pressed into the seat leather, while the guy will almost feel like he is fucking the bike itself.
Crotch Rocket Handjob
This is an easy way to get off on your bike without losing any time on the road. While you keep your hands steady on the handlebars, your female passenger simply reaches around, unzips your pants, whips it out, and starts stroking your rod. Just be careful when you cum, so the wind doesn't blow an eyeful of spunk up into your face. Better wear some eye protection just in case.
Masturbation
Sometimes it's just you and your car. That doesn't mean, though, that either of you have to end the evening frustrated. Show your car the love it deserves with these masturbation positions.
Up the Tailpipe
Warning: When attempting this position, make sure the car has not been driven recently and is completely cool.
Take an unrolled condom, slip the end inside the exhaust pipe and stretch the opening over the end of the pipe, or use a plastic bag secured around the opening with a rubber band. Squirt in some lube, insert your penis, and fuck your car.
Alternately you can insert a cyberskin masturbation sleeve or small pocket pussy into the tailpipe, add lube, and screw. Make sure the end of the toy a little larger than the end of the tailpipe or you may have trouble retrieving it.
Get in Gear
Warning: When attempting this position, make sure the car engine is off and the parking brake is engaged.
Straddle the gearshift with one foot on the floor on either side of it. You may also be able to straddle it in a kneeling position, with one knee on each front seat. Raise yourself up and lower yourself down onto the gearshift until it penetrates you, or if you prefer, rub yourself back and forth against the knob and shaft to masturbate. Use your legs to raise yourself up and down or rock back and forth. Slip a condom over the gear knob for easy clean up.
Rockin' the Backseat
Cut a hole through the upholstery of your backseat about the same size or little smaller in diameter than your cock (you won't want to do this if you have leather seats). Carve a hole into the foam deep enough to accommodate your erect penis. Lay across the backseat and hump the hole. Use a condom or insert a plastic bag into the hole to avoid creating a spunk-filled waste dump in the cushion. Conceal hole with a seat cover when not in use.
Hood Ornament
Mount a large dildo with a flanged base to the front bumper of your car using bungee cords or tie-down straps to secure it. Or use a dildo with a suction cup base and apply it directly to the bumper. Step up onto the bumper and plant your feet wide on either side of the dildo, leaning forward onto the hood for balance and support. Lower yourself onto the dong, insert it, and bounce up and down. When you're done, remember to remove the dildo from the bumper, unless you want to attract attention while driving.
