He exploded into my mouth immediately. I unexpectedly swallowed before he pulled out. He sprayed more cum over my face. My pussy sprayed in my panti...s. This, of course, is when his mother walked in. I knelt there wide-eyed, with my tits out, jeans pulled down to my thighs, drenched thong barely hiding my slit, and with cum dripping from my lips and face. Her son was on his back, jeans pulled down to his knees, with a full erection. That was a lot of firsts for me that day.I often wondered. I picked her up in the Impala that night around nine thirty. She slipped out of the house and came out to my car.Damn! She was wearing a pair of cut-off Oshkosh overalls. She had rolled cuffs in the legs right up to her crotch. She was wearing her pair of cowgirl boots (the Urban Cowboy craze had caught up with her) and her straw cowgirl hat. Under her overalls was a tight little white band of a tube top. It barely contained her tits and showed a nice line of cleavage at the top. Her nipples. I know.Ah.I see a couple guys from time to time." Okay, who?" Well, there a man named James Killibee. I see him some." Okay who else? Who did you see last." Stephanie got that stubborn look on her pretty face. "Come on Steph. You've been fucking black men for several years. Something happened recently to get your husband suspicious. I need to know who or what." Oh shit," Stephanie said with a big sigh, "James introduced me to a man a few weeks ago. A friend of his. Sweet is what he calls. I was then rubbing my dick on mom’s ass. But still, I was feeling enough erotic so I asked my mom, “Can I remove my underwear and rub.”Mom: No, now that’s too much.Me: But mom please just one time I am feeling really horny.Mom: Okay Avi. Oh gosh, you are so demanding.Then I started rubbing my dick on my mom’s ass and also touching her titties.Me: momma it is the first time that I am without my underwear and grinding your ass on the bedMom: well yes. Now just shut up and enjoy it as you usually.
