As Tina cums, even more of her warm juices flow over you. At first, you think you'll surely be washed out by the fluid, but Tina's vaginal walls are clenching tightly around you, trapping you within as her cum gushes over you. You hold your breath, waiting for Tina's orgasm to end, but it seems to be taking forever and your lungs are quickly starting to ache. Finally, your forced to suck in your sister's cum, gagging and choking on it as it fills your small lungs. Your body writhes as you drown within your sister's pussy, on her gushing juices. Your eyes bulge and your body goes tense before everything goes dark.

Tina leans back, gasping for air. The orgasm she'd had was massive. Her hand was totally soaked, as were her thighs and the floor bellow her. She didn't think she'd cum that hard before ever. Whatever had gotten into her, she thought she liked it quite a bit. There was no way for her to know that she'd just inadvertently killed her younger sister with the mind-blowing orgasm she'd had. Ripping off some toilet paper, Tina wipes her hand clean, as well as the rest of the mess she'd made.
