[MF] My Girlfriend’s mom [Cheating]

okay….time to admit it…My girlfriend is 5 months into her pregnancy and it was an unexpected one but decided to get along to with it. BTW I am Jay (23) and my girlfriend Lizzy is 22. So as you would expect I was deprived of sex for the last few months and I was just wanking and watching porn like what a usual guy would do. Last week my girlfriend wanted us to spend sometime at her mom’s place for a week. We went there and I gotta say her mom, Mrs Patterson, has a great big house, although she is a divorced woman but a very attractive woman. I always had respect her because of how kind and loving she is. As we spending time at that place, I get my urges to have sex and then I usually go into the toilet and wank for bit and come out. It was about 6 in the evening, I went into the toilet and started wanking thinking the door was closed, but the lock was loose and her mom walked straight in and saw me with my dick in my hand ”ooooohhh….im sorry …” she rushed back outside. I got myself all embarrassed and got back up quickly and open the door slowly and walk back into our room feeling all weird and shy. I did not tell my gf about this and just acted normal. Later that day, I was watching TV while Lizzy was sleeping upstairs and her came downstairs wearing one of them black transparent nightie. She got be off guard and sat next to me with her on my shoulder. ”Jay ….I know what you are going through at the moment…it is okay,…every guy goes through this at this time” she said. I was like ”i mean….im sorry….i feel so embarassed” i told and she replied ”no need to be embarrassed…you should be proud”
I could not understand what she was saying and i turned to face to ask her that but by that time she was all on her knees. i had the shock of my life but i did not want to let this opportunity go as i desperately needed a cunt. I took my willy out not even bothering about the fact that she is my gf’s mom. She took it in as if she had never seen a cock in life. Gotta admit that she was better than lizzy in giving a blowjob. I was thinking to myself what am i doing… am i doing the right thing….but i could not careless and carried on with it. She blowed me for like 5 minutes and then asked me sit on the sofa and she wanted to ride me…and she needed some attention. I was like ”are you sure Mrs Patterson” and she replied ”call me Sarah…Jay” in a seductive tone which caught me by surprise and made me so horny.I pulled my pants down and sat on the sofa with my willy straight facing 12 o’clock. she slowly pull down her panties and came close to me and stood on top of the sofa and slowly coming down. that site alone would have made me cum so much….but i waited and she slowly slided me into her and she felt so tight…”you are so tight sarah” i moan to her … she replied ”i am having sex after a long time” and i was stunned by that given how she looks and her body shape…”come on you must have had guys” i say while she goes for quick ride.
she giggled at me and moaned so much and then changed position to look at me and it carried on for a while ….before she eventually stopped and wanted to cum over her face and i got up and squirted a load on her face and then she blowed me for few mins and went back into her. i cleaned myself and went and slept next to lizzy…
