Arc de Triomph: Have your man sit on the bed with his legs extended in front of him. Crawl up to him on your knees and straddle him, lowering yourself onto his erect penis. Once you’re comfortable, arch into a back bend — but be careful not to strain your lower back. Rest your head between his legs on the bed and reach your hands back to grab hold of his ankles or feet. That’s when he leans forward and the fun begins.
