There’s nothing like doggy-style sex for deep penetration, but Backshots takes deep to a whole new level.
She should kneel on all fours on a couch or the edge of the bed, using her hands and knees to steady herself. He can then ease himself into her from behind. He can grab his lover’s waist as he thrusts and pull her back and forth for deeper penetration.
If she loves feeling like a dirty girl, have her put her head down while she props herself up on her forearms.
Play around with how you move inside of her, since many 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.
