Mrs Riley gasps loudly as your touch finally reaches its target, and you begin stroking her through her panties. Her hips buck against your hand in response, and she moans even louder. "Oh yes..." she murmurs, her eyes closed tightly as she throws her head back against the couch.
Her fingers dig into your leg, urging you on as she leans forward again, pressing her breasts against your arm. You can feel how aroused she is, and it only serves to make you harder.
