Without hesitation, I got behind her and Ken went to her face for some oral attention.I had never fucked a cunt that already had cum in it. It was we... and loose. I was buried to the balls without any effort. I was used to having to work my cock into the girls that I had fucked as I grew up. But Mom did have some muscle control. I could feel her squeeze down on my thick seven-inch shaft as I fucked into her. I was so horny and had been jacking off enough that I did not last long. Not much. It got to around 11.30pm before I received the first message from my wife. As per usual her Mum had taken it too the extreme and was completely wasted. By 12.30 they were in a taxi on the way home to ours. Just what I needed, a drunken MIL getting in the way.So basically for as long as we have been together our sex life has been great, no complaints. But as soon as my wife gets out for the evening, no natter how many drinks she has or doesn’t have she turns into the biggest slut you’ve ever. She paced up and down, her sharp heels sinking into the thick carpet. This could be a really good opportunity for her. St Catherine’s had quite a reputation and would definitely stand out on her CV. And it sounded like she’d be well reimbursed. Suddenly, things were looking up. Phil’s anguished groans drew her attention back to the bed. He was wriggling about pathetically, his thick cock swaying backwards and forwards like yacht’s mast in stormy seas. Helen glared at him angrily as she eased. My cock began twitching but I did not show any outward interest, instead I began breathing very slowly as if asleep and let my hand drop from caressing her back onto the bed behind her. This didn't stop her from caressing my stomach and, very surreptitiously her hand moved closer to my cock. Then I felt her right leg rub against mine with her knee resting on my thigh. I also felt her warm pussy rub against my thigh but I turned slowly onto my right side so that my cock would be within easy.
