Start doing a sensual massage
From Create Your Own Story
As you watch the next movie with Mary sitting between your legs, you begin giving her a massage. Your hands rub up and down her back, relaxing her, and then you move your hands around to her stomach. As you rub her stomach, your hands start brushing against her tits. Finally, you run your hands over Mary's boobs, and you begin to gently squeeze them. Then you go back to massaging her back. As you do, her bra gets in the way. You notice this and ask, "Hey, Mary, would you mind if I took your bra off? It's kind of getting in the way..."
"Oh, sure, go ahead, Julie. If it makes it easier, we could just take my shirt AND bra off," Mary replied, looking back at you.
"That would make this a lot easier," you tell her, lifting her shirt off and over her head. Then you unclasp her bra, and she slides it off of her arms. When she leans back against you again, you put your head over her shoulder.
