I don’t think that this busty xxx actually needs to have a lover to have enough sex in her life, because I imagine that her husband will take care of keeping it well stocked, precisely fearing becoming a cuckold. But the morbidity of infidelity is stronger than it, nothing tastes better than fucking someone else when you can’t, and becoming an unfaithful married woman gives you a status that cannot be explained in words. Plus, if your lover is a black guy with a huge cock… that makes it even better.
