Scott- Kissing your neck, making you squirm whilst he pounds into you in a spooning position, using one of his arms to hold one of your legs up at an angle.
Stiles- eating you out. He feels blessed to be with you, and makes sure you know it by regularly using his skills to go down on you.
Derek- Doggy style. He can reach all the spots that make you scream and convulse in pleasure that way.
Jackson- blow job. Less effort for him. He'll often take pictures while you do it, and show you later, explaining how good your mouth is.
Isaac- as much as Isaac loves a cuddle, he also loves to tease you. To run his fingers over your thighs, until he reaches where you need him most, as you beg him.
