Few months passed by, I got into my 3rd year in university, Still I enjoyed porn and sex story. Then with reading more incent, I wanted fuck mom. I mean, I knew grandpa fucked her weekly and seeing that ass I needed to come up with something. So I was thinking of a plan. Then this crossed my mind. As grandpa was so cool with this, he convinced grandma for sex with me, maybe he could do the same with mom. Casually while have chat I said “grandpa, I need a favor from you” he said tell me, “grandpa you have being fucking mom for some time now, I also like to fuck her, can you help me as you did before”. Grandpa laughed and said “will she let you fuck her?” Then I said “that’s why I need your support”. He said give me sometime ill come up with a plan. I thanked him and came home.
Few days after, grandpa asked me “I got a plan, shall we all 4 have sex in same room, halfway we will change” I asked will it be possible? He replied “let’s try, when are you free next?” Because I was waiting for this I said tomorrow I can. Then grandpa “ok tomorrow morning we’ll come” As said I was waiting figures crossed. Then next morning they both came to our house around 10am. Me and mom was having a chat in the living room. Grandpa took the first step, “shall we have some fun?” all of us laughed. Grandpa came near mom and asked shall we, then mom also stood up from chair and went towards the room. Before entering mom asked “don’t you 2 going?” Then grandma said “yes we are, in his room today for change”. Mom acted cool and both went in. Then myself and grandma came to my room. Grandma “grandpa said me the plan and laugh, your naughty boy”. I was blushing. Then I asked, how is it going to work. Grandma said “let us 2 start, grandpa will do the needful”.
Actually grandma wasn’t wearing any panty or bra, we striped and started kissing and oral sex. In about 20min time grandpa came to my room, I felt bit shy as I was naked and same time seeing an old hairy man naked. Grandpa “come join us”. Then grandma said “let’s give a try with a smile”.
Then we all 3 went to our guest room, mom has gone to bathroom, as we entered she also came out. Mom “what is this?” Grandpa said “don’t worry, let spice things for me, I like to have 2 at once, please come” mom looked shy and so as I, with a fully harden dick. This was the first time me seeing mom naked. Her boobs were hanging down with dark brow nipples, then had some fat on her tummy, then a hairy pussy with wide hips. I had the front view (had some stretch marks). Grandpa directed mom to bed and made her sleep, she was looking at me from side of her eye.
The grandpa folded mom’s legs and spread them apart, wow, I was frozen, to see her dark pussy, she also had big outer black lips and pink inside. Grandpa started licking mom pussy, and grandma went and started sucking mom’s boobs. I was standing and enjoying the view. Mom started to moaning eyes closed. Then after about 5min, grandpa asked “son take this over, and went and stood near moms face and asked her to suck his cock, so I slowing bent and started licking the hairy pussy. Then mom at once said “don’t” but grandpa said “please concentrate on this”. So I tongue deep into the pink pussy, and from top of my eye I was watching mom sucking the dick.
