My thoughts exactly.Back in 8th grade it was okay but we're grown up now so it's mandatory to slob,bob and swallow.my mom always told me if a chick doesnt swallow she just aint worth fuckin more than once.
scientifically it's not good to get your load somewhere it's not supposed to visit, cause it may reach blood through any abrasions and develop antibodies against your sperm and maybe all sperms ,,, you may get her infertile with that ...
