Better feeling for her.
And less work for you. Make the most of it before the batteries run out.
Your tits are gorgeous. Your pussy is beautiful.
That way, you have a chance to calm down while she revs up. Look her in the eyes.
Or at least look at her body. Let her see that you love the sight of her.
That you find her attractive. Anywhere you can reach.
Play with her breasts. If she likes it rough, smack her on the ass.
Or give her a taste of her own medicine by digging your nails into her back or thighs. Lift up her shirt.
