Terri found the spot between her plump cuntlips where her older sister was fingerfucking herself. This time Terri used her forefinger, forcing it up slowly against the partly torn membrane. There was a sting of pain that wasn't bad enough to make her stop. Up inside herself, she was feeling a softness, a tightness she bad, never been aware of.
