I have been a breast worshipper for quite a while and I have tried many of these techniques on my ex wife, and she loved it. Her favorite was when I would lay against the headboard half reclined and have her lay against my chest. I would gently play with her nipples until she was soaking wet. She would get so excited that she want to rub her pussy, but I would make her keep her hands on my knees. I tried several times to get her to reach orgasm by nipple and breast stimulation alone, but it never happened, but boy did she cum like a rocket once I put my tongue on her clit!
