Go for some ass play.

Jake ran his thumb up and down her anus, as extra stimulation. He stopped with his finger right on her hole and applied a bit of pressure, to gauge her reaction. She moaned softly, which he took as an approval, so he started gently pushing his finger in her tight ass, while continuing his thrusts. When his thumb was half-way in, he stopped and just kept it there, making only subtle movement.

Michelle was moaning louder and he knew she was about to come. He kept fucking her and soon he felt her clench her ass and back and heard her familiar orgasm moan.

As she laid in the same position, recovering, he pulled his finger out and continued to fuck her with long, slow thrusts. At the point of no return, he pulled out and shot his cum on her ass, then he entered her again for a few finishing thrusts.

When he was done, he kissed her back and laid down beside her.
