Ok so my 62 yr old mother-in-law (lynn) is spending New Year’s Eve with us as her husband left her for another woman last year and she’s lonely. We are all getting drunk in the living room and I go to the kitchen and start talking to her. She’s quite drunk and tells me about how she’s finding it hard to take that her husband (my father- in-law) was seeing another woman. As she’s telling me all this I can’t help but look over her tiny petit figure. I mean she must only be 4ft 5. Anyway she’s talking away and my thick 10” cock is getting hard. I start to ask her questions like “do you miss sex” as she tells me unfazed that she hadn’t had sex in 2 years and she was sexually frustrated. I can see her getting excited as things heat up and just sensing and opportunity I took her hand and led her into the bathroom connected to the kitchen. She didn’t resist as I locked the door behind me and pushed her against the sink. She just looked at me breathing heavily. I took my cock out as she looked down on it saying “what’s happening”: I just unbuttoned her blouse as I opened it up pushing her breasts over her bra. She stood still just looking at me as I pulled her shirt up and hitched her onto the sink, moving her knickers aside and sliding my cock into her already wet pussy. She groaned loudly as my huge length pushed deep into her lifting her legs either side onto the air and started to thrust my cock in and out of her. She was so horny her eyes wide looking straight at me as I fucked her hard. Just then she started to scream as I covered her mouth watching her cum. I pulled out and pushed her onto her knees her eyes looking up at me as I grabbed her head and fucked her mouth, “You want my cum” I said “mmmm” she replied as I shot my hot spunk down her tongue. She swallowed it all as we both stood up and composed ourselves. We left the bathroom like nothing had happened and went into the living room where I’m sat on the sofa writing this. Amazing
