A Valentine's Day present is left for Gwen - a bottle of erotic breast enhancing massage oil, along with a note. Innocently, Gwen drips the serum onto her big tits which results in her arousal. As she gets more horny, Gwen's heavy breasts suddenly expand. Popping into a giant X cups, she can't believe her new body. After more rubbing and nipple pinching, she gets another gift - a sexy slutty red bimbo outfit. She wears it in hopes she'll get to keep her new rack, but needs to cum before she heads out to see her besties for Galentines day.
