Mommy is in town and she is staying with you and your girlfriend. it's the first time meeting her and wow! she sure does look a lot like mommy, huh? ;) later that evening, mommy gets on the phone with her friend back home after the two of you have gone back to your bedroom. All of a sudden mommy can hear soft moans coming from the bedroom. Her friend convinces to her to peek, remembering all the fun they had in college together, playing. Fucking in their dorms while the other one listened. But it's her son, she can't.. she shouldn't. But as the moaning gets louder she can't help but take a look through the cracked door. While she is telling her friend what she's seeing, mommy can't help but start touching and rubbing herself. Her friend on the phone does the same. Her son has his head buried in his gf's legs, eating her pussy. She can see her wetness and knows her son is going to make her cum. Mommy slips her hand inside her panties. After she cums, she can finally see her son's cock. Its so big! She is even more turned on, telling her friend everything she see's. Her son flips her around, teasing her wet pussy with his cock. Mommy wants him to give it to her, and watches as he slowly slides it inside. Now she's so horny she cant help it, she slips off her panties and starts fingering. But.. is her son... looking at her? No.. but then.. he winks at her! He won't look away from her while he slams his cock into his gf. Mommy spreads her pussy lips for her boy, encouraging him to fuck his gf while she watches..
