i ejaculated into a sock and a small amount of cum seeped through the sock and a small coating of cum went on my finger adn a feeling of wetness on my hand. then i decide to wash my hand with water (no soap) rather quickly. but since there was no soap i asked my sister to get some soap for me and pour it on my hand to wash it. but the container touched my hand and she touched the container where it touched my hand. so is there a chance of pregnancy from that if she touches anything near her genitals
