You and your best friend are having a competition on who can say the rudest word, when your mom walks in to ask if you are both okay. She spots you both giggling, hiding something and soon gets it out of you. She laughs when she hears the words you boys think are rude, and has some rude words of her own to spur you on… Then she has an idea! If you boys enjoy naughty competitions, she thinks you should compare your penis size just to see who’s is bigger. She promises she wont look, but she does, and excitedly notices that yours is a little bit bigger than your friends cock. She then takes things one step further… she wants you both to jerk those dicks and see who can cum quicker… but whoever cums first is the loser, and whoever can hold off the longest, gets a very special reward for showing her your stamina. It isn’t a surprise that at the mere sight of her pussy hole spread open, your friend has a little accident on the carpet, spilling cum everywhere. He is embarrassed, but your mom soon gives up the reward to her son, which is to fuck her cunt until she gushes squirt juice all over your cock! Your friend is instantly hard and tugging at it for a second time as he watches your mom use your dick as a play toy, sliding along it to make herself feel good. She moans and squeals and tightens around you, pumping away with her pussy, taking all of you in easily and banging hard against your balls. You cannot speak, you are fully enjoying the sensation, your mom using you as a masturbator. Your friend excitedly jerks, cumming again at the sight of what is happening in front of him. Your mom then pulls off you, taking your dick in her hand and wanks you off onto her pussy and swollen clit. She wants to SEE how much cum you can produce, and the faster she uses her hand, the faster you are pushed to the biggest fucking orgasm of your young life! You can feel the tip of your cock rubbing against her soaking wet, dripping cunt and you just can’t hold back any longer… Juice and biscuits anyone?
