The fourth installment in the series showcases full-on breast cross-ties, a specialty of big-tit models! Popular favorites from previous hits like "Big Tits Tied Up 1, 2, 3, and 5" return, flaunting their E-cup or larger breasts. Even while tightly bound in a cross pattern over their breasts, they exude both erotic tension and sensual release—this is a must-see fetish title!
