As Cassia is seemingly getting laid and she doesn't have any skill trained that could relate to birth control through alchemical substances, herbs, or medicine now might be a good time to mention how things could go.<br/><br/>For non-consensual sex, we're using the death save mechanic. Upon failing 3 times, the heroine will be at the mercy of the rapist, they may do whatever they please, humiliate, impregnate/breed, finish off etc. the character. (Player offs are taken into account obviously) If the character used some skill, potion or method to prevent pregnancy, they might still get away without bastards later, though they'll likely become captives after the 3 failed saves.<br/><br/>As long as it's consensual sex it's only through RP, however NPCs will act according to their own alignment and personality traits/flaws. If at the climax the npc can choose how to finish they will do so accordingly. For example, a considerate person might ask the heroine where to spill their seed, or just pull out by default. Others may not be so polite and shoot on the ladies face, breasts or back if they so like, or even creampie without asking, in which case the lack of birth control will be problematic for the heroine. This can be avoided in a number of ways, such as anticipating the finish and roleplaying the character to be in control or "top" and deciding how to end things (for example finish with a blowjob, tittyfuck or anal), or making a persuasion/deception/intimidate check to convince the partner to do as asked and not put a brat in her.<br/>The reverse also works of course, if for some reason a character wanted to be creampied they can lock legs behind their partner to prevent them from pulling out, riding them non-stop until orgasm, or of course making a check to influence their behavior (begging them to come inside, telling them it's safe, etc).<br/><br/>For unprotected creampies, I'll make a roll and under an 18 or higher the character gets knocked up, the fact to be revealed soon after in game, leaving the character and player with a period of uncertainty. Using some kind of birth control will drastically modify the DC of this check, greatly reducing the chances of pregnancy (the effect may vary based on the skill check to prepare the countermeasures).<br/><br/>Altered races of course being sterile don't have to bother with this at all, they can't get pregnant due to their transformation or physical mutations.<br/><br/>...<br/><br/>Now, wondering how many PC's will get knocked up before even setting out on the adventure!  ;D
