A Couple of Sexy Lesbians love to fuck hard! It's no secret that lesbians get committed to one another quickly and don't cheat. The old joke about lesbians renting U-Hauls is absolutely ridiculous, and it's certainly not true for everyone. While some straight couples do become "we" very quickly, lesbians don't cheat. And while homosexuals do commit to their partners, some heterosexual couples do, too.
