*use of taboo trigger word, gaping, anal creampie* *emphasis on butt/butthole opposed to ass/asshole* Your sister caught you fucking another girl other than your girlfriend in the BUTT, and she uses it to her advantage... She says she won't tell your girlfriend if you take your sister's anal virginity, as her boyfriend doesn't wanna fuck her in the butt. She blackmails you, sucking you and slowly lowering her tight, virgin butthole on her brother's cock. She slowly gets used to it, and then ends with her bouncing back hard on your cock begging for your cum deep in her butt...
