Deciding that there was no possible way anything could've gotten into her vagina without her noticing, Tina continued to finger herself. It was probably just her imagination working on her since she was so horny. She decided to fix that problem, working her finger deeper into herself and pushing her thumb against her clit. She feels the pleasure growing, a climax becoming more and more imminent. Tina's fingers start to move faster against her pussy.

Inside, you feel yourself being prodded even deeper inside your sister by her thrusting fingers. This is not going well at all for you and at this rate, you'll never get out. Your mind fills with horror at the thought of being trapped inside your sister's twat for the rest of your life. You try to think of something to do to get yourself out of this mess, but it's no use. And it really is a mess, you think, as your body becomes more and more soaked with Tina's juices. You resign yourself to be being trapped for the moment, and try to just avoid Tina's jabbing fingers, which seem to be coming at you even more rapidly now.

Sweat beaded Tina's forehead as she panted, letting out soft moans of pleasure as she fingered herself. Her hand was becoming a flurry of motion as she got closer and closer to her orgasm. Finally, she cried out as she went over the edge. Her honey gushed from her cunt, soaking her hand.
