我吮吸她毛茸茸的阴户，直到她射在我嘴里，作为回报，她骑乘我勃动的鸡巴，直到我像一匹发情的马一样高潮。

My mother had to go out to pick up my little sister from school, we took advantage of this time to satisfy ourselves, as my stepsister couldn't handle being horny, madly asking me to make her cum. As she always returns my favors, I sucked her with a lot of talent and patience until she couldn't take it anymore and she squirted like a bitch in her mouth and I swallowed her juice contently. Obviously afterwards she rode me until I came inside her.
