Sister tries to get brother to break his New Years resolution, he’s bet her friend he can go all through January without cumming and if he does she’ll fuck him. But sis knows her brother can't resist her and would much rather fuck her instead of her friend. I'm much hotter & better than her and sis decides to lead you astray and starts pulling out her tits and telling you to get your cock out. It's not long before you end up fucking her tits and mouth and she tells you to fuck her pussy. Fucking you missonary and riding your cock till you unload deep insider her. Looks like you lost the bet bro, but don't worry we'll have plenty more fun before the month is out.
