The person that you'd never expect to turn up at your door does just that, your Sister. It has been a while since you last saw her, and even then things were awkward, all because of what happened between you 7 years ago... She's split up with her boyfriend and your parents are downsizing so she doesn't really have anywhere else to stay, would it be crazy if she stayed with you for a little while? You knew she wouldn't ask unless she was desperate. Days pass and things seem pretty normal between you too, she opens up about why her last relationship ended. You start to notice you can always see a bra strap or top of her bra in her shirts. She tells you she has a lingerie addiction and her ex didn't appreciate it. You definitely do. She starts to give you more flashes and tells you that you can look but can't touch. One day she takes your hand and lets you stroke her stocking and even her bra. She catches you watching her trying on lingerie, she tells you that you need to talk. You seem way more mature compared to 7 years ago. You actually appreciate her and her lingerie. You apologise for what happened in the past. It shouldn't have happened and it was really bad sex. You want to make it up to your sister. You lick your sister's pussy until she cums on your face. The sexual tension has been building for days, she is so wet for you. She gives you a hand job and blow job until she needs your cock inside of her. She rides you in cowgirl and you fuck her in missionary before blowing a big creampie inside of her. You are still rock hard, she sucks your cock until you cum on your sister's face! Maybe living together isn't such a bad idea.
