She lets out a small gasp as you undo her bra and remove it from the way. Her breasts spill free into your waiting hand and she squirms a little, feeling exposed in this position with you touching her like this. Her nipples harden even more under your fingers, aching for more contact. "I... shouldn't..." She whispers again, trying to resist the pleasure but failing miserably.
Her hips rock against yours as she gives herself over to the sensations washing over her. The feel of your warm skin pressed against hers, your hand squeezing and massaging her breasts... it's too much for her to handle. "Please..." She pants, arching into you again as she tries in vain to get closer. Her fingers dig deeper into your shoulders, leaving marks behind.
