Sluts have to earn the chance, make sure she knows that! At this point you can remove clothing. Now inform her that she can't come until she has satisfied you.
Have her give you a nice blowjob. As she's sucking you may play her with her and tease her. Lightly graze her clit. Make her associate her pleasure with yours. If she stops so do you. If you need to stop touching her to prevent cumming..pull out of her mouth.
While she cools off go back to massaging her breast and lickin the outer lips to keep her sex-crazed. Repeat this as many times as you would like :)
