“Mystery of My Heart” is a sensual film that opens with sexy brunette Elena Vega whispering sweet nothings to Nick Ross. The meeting, which was directed by Ariel Piper Fawn, intensifies in a sensual manner as the lovers caress each other’s bodies. Nick licks a trail up to her lips, pulls her black lace bra aside, and nips her erect nipples affectionately while Elena straddles her man, her stockinged legs gripping his hips. Elena licks the length of Nick’s erect cock and puts it between her lips when she is completely nude, save for her garter belt and stockings. She gives him a generous blowjob while sucking it and sliding her tongue all over it while looking up at him. In cowgirl mode, Elena glides up and down on Nick’s tight pussy while swaying her hips to drive his inflexible erection deep. As she rides, her ass ripples and her breasts bounce in his face. Then, she comes up to sit on his face and gets fingered and devoured in a powerful climax. Nick pushes into Elena in missionary once more, accelerating the tempo till they explode together as he thrusts steadily to make her groan with delight.
