As the title suggests, sexual tension constantly builds between the two lovers. Despite being at a crowded party, their attention remains solely on each other's lustful desires. They retreat to a private room where the woman teasingly wears off her clothes while the man hesitatingly removes his pants. The woman's cunt is eagerly waiting for his cock as she lies on the bed naked. He enters her tight cunt and begins thrusting slowly to build up her arousal. She moans in pleasure as he fills her up and her sensitive walls contract around his shaft.
