You keep plowing away at your sister. She groans and clutches your rump, holding you close to her as she yowls. "Oh, Oh God, don't... Don't go!" She keeps your hips pressed against hers as she climaxes. Her channel getting flooded with her liquid desire.
You can't help it. the warmth of your sister's climax and the activity inside of her channel brings you over the edge. Your tip is pressed firmly against her cervix as you release, panting heavily. You blush hard as realization hits that millions of your tiny, fertile sperm are inside of her. |
