Thats right - vaginal enlargement.
A lot of people voice their concerns about going to big, but I think woman can get bigger just like us. If you are growing then the girl you’re with regularly should stretch over time to accomadate your size. If you don’t believe girls can stretch you need to do a little porn search on Kazaa. There are a couple vids on there where girls take dildos with huge girth and they ride 8+ inches deep. My belief is that if you’re big, but you can get it in her then shes going to be practicing VE.
