Today's Quickie Sex Position
Girl is on her back and Guy climbs on top and enters Girl just like plain old missionary sex. However, Girl wraps her legs around Guy's back and pulls herself closer while Guy lifts his hips just a little as he strokes.
Just do what's listed. If Guy isn't hard, a quick blow job or a hand job with a bit of lube should fix the problem. Girl may have more fun if she adds a bit of lube to Guy's man part!
