I’m 24 yo
I have a gf for about 4 years we’re pretty young (she’s 20) and I have pregnant and breeding kink.
Every time i see pregnant woman I get hard
I almost always want to cum inside her pussy (she’s on the pill) and it just make me so hard
Why is that even a kink? Isn’t it the whole purpose of sex?
Why I feel ashamed?
