Put a hand under her shirt
From Create Your Own Story
You take one of your calloused hands and put it under her shirt, giving a squeeze to her right breast, and gently rubbing her stiff nipples. Her large breasts jiggle with her every movement, and her aching nipples poke through her shirt. You wish you could see what she looks like without the top, but your happy just feeling her soft luscious tits.
She takes her hands and squeezes her tits together, taking her thumb she rubs small circles around her nipple.
Practically ripping her shirt off in the process, you squeeze each of her nipples and squeeze her tits together, not that she minds if her moans are any indication.
