My girlfriend (F19) and I (M20) are looking to have a gang bang with a few others males. We both have a kink for cum and would love if they could all fill her with their loads during. After I would eat her out and clean it all up. She is on birth control and it has been very effective for over a year (I have been cumming in her six s then) so we aren’t worried about that. We do know there are more risks then just pregnancy like STI’s, but we really really want to furfill the fantasy if possible. What recommendations do y’all have? What have y’all done in the past? We have thought of taking preventative measures such as medication to help, or requiring tests from any males before they can partake but we aren’t 100% sure what best or what’s too much. Any advice?
