The atmosphere is charged as they both react similarly, her screaming loud enough for everyone nearby to catch some of what happened, and even though there was no consent or explicit agreement beforehand about such activities happening within that space, things escalate quite rapidly once started due probably mostly out of sheer excitement combined perhaps unknowingly also potentially influenced slightly by mutual curiosity mixed together with possibly just plain old-fashioned miscommunication gone awry; ultimately culminating however unexpectedly so clearly becoming yet again more than likely surprisingly indeed maybe almost certainly inevitably unarguably forever changing life going forward. definitely proving case after all cases anyway.
