Find yourself a chair or sturdy stool for this sexy little number and ask your man to sit on the corner. Sit on his lap facing away before bending down to support your weight on your arms and put your legs up and back so you're lying on his lap. You might have to experiment - tough job, I know, to work out when is best for him to enter you but this position gives him an exquisite view of your bottom and makes it easy for him to take hold and work up a sexy rhythm.
