Spurred on the taste of my sister’s juices on my lips I fucked Mom with half a dozen more strokes before a started spurting my virile young seed dee... into my Mom’s hot snatch. I think I spurted about 3 or 4 times when I withdrew my softening cock with a slightly more audible than expected “plop”. As I sat back admiring the view before me, waiting to see my cum pour from my mother’s cunt, I was amazed to see Mom clenching her pelvic floor tightly.“Help me up, Jake,” Mom said, keeping her knees. At three months pregnant, she was just starting to show with a cute baby bump curving her belly. Her large tits swayed and bounced beneath her as Clint fucked her hard. She moaned, slamming her hips back into my big brother’s strokes. His muscular body rippled as he grunted, slamming his hips forward, taking her so hard.“Big brother!” I shrieked and threw myself on the bed beside them. I thrust the pregnancy test before his face. “Look! Look!”He froze in mid-thrust into our mother’s pregnant. .or so I thought. We are heading the wrong way. So I ask, "Hey, where are we going?" "Not the library" she says with a smile. She figures its too nice out to be sitting in a library. She jumps on the Kennedy expressway and we race down to a forest preserve called LeBagh woods. We park and go sit on some picnic benches.She has this crush on this guy from school last year. But we are thinking he graduated or dropped out, cuz neither of us has seen him this year.We joke around and talk boys in. My mom was still concerned about what I had done with Tammy, worried that she was too young for me to go any farther with. Showing her how to cyber on the Internet and hooking her up with some guys that liked to masturbate for her wasn't a problem for her since she could have found that out for herself. It didn't hurt that my mom liked it when guys sent me pics of them cumming her so she couldn't really say anything about them doing it with Tammy's. If anything she was glad I had helped her.
