If you are daring, up for a challenge and super flexible, see if you can get yourself into one of these hardcore positions. Bonus points if you remember to stretch first.
Have your partner bend her knees, sit between her heels, then lie alllll the way back (she can go ahead and use a pillow for her head/back if she can’t get all the way there). You get off easy in this one—in all that implies—by mounting her on all fours. In this position, she can get some well-aimed internal stimulation, and she’ll have hands free for A+ clit access.
The Reverse Wheelbarrow
In this position, your partner lies on her back—that’s it, that’s her job. You stand at her feet, lift her legs and hoist her hips up to yours so that you can mount her. (Your partner should keep her chin tucked to her chest.) You’ll be able to hold her up longer if you stand back against a wall and hold some of her weight against his body.
The Safety Piledriver
The Piledriver is a porn favorite but rarely appears IRL because it ends up with everyone in tears and neck braces for all. Try this modified version instead: Have your partner lie on a couch with her butt up on the top of the back cushions and her head hanging off the front of the front cushions. You stand over her, feet on the seat cushion, bending your knees and holding on to the back of the couch (safety first!). Still hot, but no on-call medics required.
The Deep Lunge
As you lie flat on your back, your partner gets on top with one leg straight down between yours and the other bent so her foot is beside your chest. She’ll have way more leverage and staying power, plus she can grind as she pleases.
Have oral sex like the astronauts do (note: not actually verified.) Your partner lies face down on a bed with her hips at the edge of the mattress. You stand by the side of the bed, lift her legs over your shoulders, hold her up by the hips, and get to work between her legs. Floaty and blissy for your partner, semi-strenuous for you. If the oral and hoisting combo is too much, you can kneel and replace the oral with a hard-working toy.
