Forplay-with Breast fondling
Guy may Place a hand on her breast and softly caress it. At the same time use thumb to feel how hard her nipple is. Usually at this stage she'll want her bra to be taken off so that she can really feel guys hand. So his hand may reach around her back and undo her bra clip (that is if she hasn't already).
Mow guy can take a moment to just admire beauty of her naked body. He can tell her- how beautiful she looks and how much she's turning him on. Then he may take her nipple into his mouth and caress her other breast with another hand.
