Mary and I fucked hard, talking out a bit of a fantasy where she'd brought Jamie along to one of our meet ups, so that we could teach him about sex pr...operly. Just the fantasy of me watching her wank, suck, fuck and piss on her child was too much, and within a few thrusts I'd cum deep in her cunt. We caught our breath then went to the bathroom, Mary kneeled in the bath and I stood over her as I pissed. A full 2 minutes later her body was drenched, but she was greedy and told me the next part of. It was freezing for me. The climate also was so chill but her hand was so warm and her lips were even more warm.She started to give me blows and I was flying in air.After few minutes I said her I am about to cum and suddenly she stopped sucking. Within seconds I got my senses back. I asked her why did you stop now? Continue to suck please. She said sorry, I am satisfied for now ? thank you. I am leaving see you in the evening. I was so damn horny and she is leaving me in the middle. Shit… What. My cock was primed and ready, but I knew that my sister was not, and I continued to warm her up with my tongue.I reached up and cupped one of her breasts, before finally pulling the bra down to reveal the perfect little pink nipple poking out at me. She brought her hand up and tweaked it, glancing down at me and making a moments eye contact. ''I think it's time Mom showed you some love,'' I told her forcing myself away, I ran my fingers through the brown locks of my Mothers hair and held it. A normal person would have used the urinals, but not me. I was very shy – I wasn't going to chance that a pervert could walk in and see 'ol bobby (I nicknamed by dick). The chances were diminutive... but still. No.I was pulling out my 7 inches, and I heard someone else walk in. I thought nothing of it, and started peeing. 'Lala la lala' my mind went. Peeing is one of those absent-minded activities that us guys get used to, and just enjoy.Finishing, I zipped up and flushed. Then I walked out of.
