There’s nothing like doggy-style sex for deep penetration, but Backshots takes deep to a whole new level. Play around with how you move inside of her, since only subtle movements are possible here. Try short, quick strokes to massage the G-Spot area, or try long, slow, languishing strokes when she wants you deep inside of her.
Kneel on all fours on a couch or the edge of the bed, using your hands and knees to steady yourself. Get your man to ease himself into you from behind. He can grab your waist as he thrusts and pull you back and forth for deeper penetration.
If she gets tired as she nears climax, have her put her head down while she props herself up on her forearms.
