(F4M) Horny older brother wakes up to sis in your bed

It's the middle of the night when you wake up to a loud boom of thunder. It takes you a minute before your realize you have a visitor in your bed, your scared sister clinging tightly to you and softly snoring. I've been afraid of storms for years and you were always the one I ran to. Though tonight something is different, you're hard as a rock. You decide it wouldn't hurt if you used me to get off while I'm asleep. If interested message me a starter. My characters name is Mae, my main kinks are creampies, somno, cnc, dirty talk, domination, being pinned down, biting, humping/grinding, body job (ass/tit/hand), ect. My main limits are no potty play, no unrealistic sizes (no double digits)
