Mature granny lets her grandson pound her pussy until she cums repeatedly

I’d just turned 20 yrs old, sat on the sofa at my grandma’s, my grandma sat with me, showing her stockings and knickers, my cock was stiff,I tried to hide it by placing my arm across my groin area, but grandma was wise, told me to move my arm, my stiff cock was trying to pop out of my shorts, she giggled, then placed her hand on my shorts, touching my cock, sending a sensational tingle in my groin area, she told me to lift up.she pulled my shorts down, then began wanking me off. I had a strong urge to cum I had to tell her, to slow down or stop, because I’m on the verge of cumin, she did stop, then took her knickers off wrapping them around my cock it was the first time I’d ever had that done, she began wanking me again, in less than a minute, I shot my load on grandmas legs,pussy and my tummy, I was very excited my erection stayed, she said she can help with that, she sat on my legs facing me with her tits in my face I undid her Bra, sucked her nipples, why she placed my cock between her pussy lips,rubbing her pussy up and down with my cock she began to breathe heavily groaning with excitement then Gushhh, she cum on my cock, then told me let’s go to bed and carry on in the bedroom, once on the bed she told me to lick her clit and finger her pussy, where she came again, I put my cock into her pussy banging my grandma’s pussy until we both cum in many positions,
