A sex position known as the "Double Decker" is named from the ubiquitous double-decker buses that can be seen all over the globe, but especially in London, England. The penetrating partner lies on their back in this type of rear entry intercourse. After that, the receiving partner will lay on top of the penetrating partner with their back to chest and will use their feet and elbows to prop themselves up. If the receiving partner is willing, the penetrating partner can enter their vagina or anus.
The double decker is a great sex position for stimulating the receiving partner's prostate or G-spot since it is a rear entry sex position. Additionally, the couple can effortlessly transition into several sex positions, such the spoon sex position, while in this posture.
