How do I know? I'd seen it happen often enough when I lived under her roof. She usually went astray when Dan was working away for a few days, and it f...llowed a predictable pattern. One of Dan's so-called mates would drop in, usually on a false pretext. Beers would appear from the fridge, and as Mum and Dan's friend steadily consumed them, the conversation gradually became more loaded.Ignoring my presence, Mum would flirt outrageously with her 'guest', and when this was reciprocated, I knew it. She started calling my name and the moment she started getting loud i used to lean in and kiss her and bite her lips. We reached a point of maximum satisfaction and it was time i empty myself in side her. I desperately wanted to have the feeling of cumming inside a woman. I asked her if i can.She said she just finished her cycles and today was my lucky day so yes i could cum inside. Hearing this i started to pump her really hard and fast. I could feel my self build up and the moment i was. It's quite difficult at times! When out of nowhere I receive a message, "my girlfriend is feeling horny and want to suck on a strangers cock, she loves cum and I love to watch" I was skeptical at first but sent a rapid reply... "Sounds horny to me, love to help you both out when did you have in mind?" My heart pace increased... I had a fast reply, "call in your interested" followed by their number. that was it, instant hard on, do I call? Is this real... i'm horny at the thought so decide to. "Fuck me!" she cried over and over. "Fuck me... fuck me... fuck me!" Her hands moved off his ass and up his back to his shoulders, then his head. She clung to his hair, pulling it without knowing, her hips gyrating with wild, frenzied action. She lifted her head and bit into her son's shoulder, trying to stifle the screams in her throat. The wetness of her cunt increased until the insides of her smooth thighs were slippery, the cheeks of her rounded ass glistening. Her cunt was pulling at.
