Having a hot step-mother is not that unusual these days but a hot step grandmother is a thing to behold, especially when all she wants is to play with your dick. After I've spent an afternoon in the sun helping out in her backyard, she offered me some iced tea and to help myself to a refreshing shower. I thought nothing of it but her intentions became clear once I got out of the shower. She was waiting for me and she knew exactly what she wanted. She looked even hotter naked and I got a hard-on seeing her amazing huge tits. She pushed me on her bed and started giving me an amazing blow job. Now this was truly a woman of experience and I couldn't believe how hungry she was for my cock. She really used my dick as her own toy. She nibbled, poked, licked, tapped, wanked, sucked my balls, the lot. I just laid there in ecstasy and it seemed she would never stopped. I finally came into her mouth and she swallowed every drop of my cum.
