“Open your mouth, sis.” I repeated.She wrapped the tip of my dick with her lips. Then, I felt her tongue going in circles around it, as if she wer... French kissing her boyfriend. If I hadn’t been phimotic, I would have cum right there.I grabbed her pigtails to draw her face closer to me. My sister gagged as my cock penetrated her throat. I could see the bulge of my cock on her neck as It kept going up and down. That was my breaking point.I felt the heat rising from my testicles. I clenched my. "UGHHHHHHHHHHHHHHHHHHHHHHH!!"The suckling 'mouth' was now approaching the junction of her thighs. A deep intake of breath and a longer moan was heard as the 'mouth' left her abdomen and a long, warm 'tongue' curled around her straining clitoris.

I do remember once when my uncle picked me up, he said that his friend was going to come over and hang out with us and that he would probably spend the night. He stated that 'he and I play like you and I play'. At first I didn't get it, it didn't register. But then he said, 'He loves sucking my cock and he loves for me to fuck him in the ass.'

She gave me a funny look, but before she could say anything I said:"I don't need you kissing me with a mouth that has probably just sucked some other guy's dick.".
