I’m in the third trimester and I think it’s about time I told you my secret - your cum is what got me into this state. My step-sons jizz is what knocked me up. I proceed to tell you exactly how I collected your cum, becoming so horny that I playfully tell you to take your cock out for me, sucking it before riding you until you cum inside me. I’d blame it on the pregnancy horniness, but I was horny for my step-son well before that, wasn’t I? (;
