Fucking is technically, and physically, pretty damn easy. Any adolescent, shit-for-brains can do it (even you!), so don’t sweat the logistics. All you need to do is get her naked, yourself naked, then ease your erect penis into her lubricated vagina, do your best jumping-frog impersonation and 3 minutes later — KA-BLOOIE! — you’ve painted her uterus with a coat of active spermatozoa.
