So I am standing there totally stunned with a bottle of oil in one hand, jaw on my chest, looking at my MIL's bare backside & her nightie up near her ...armpits. She sensed my embarrassment & said "I don't wear pants to bed." She giggled & said "surely you've seen a bare bum before, common where's that oil." (She was a pretty open type, use to sunbake topless etc, so I just dismissed her nudity now as her being her natural liberated self. Maybe the drinks had made her a bit more daring? But. She just increased her tempo of sucking my cock. After several minutes of her sucking she raised up and said “watch” and then proceeded to swallow my entire 6” cock. Her nose rested on my smooth shaven mound. Then she licked my balls. What a wonderful blowjob I was getting and it felt so good I had stopped fingering her.She kept sucking and swallowing my cock for almost 5 minutes when I told her I was going to cum if she didn’t slow down. Well she didn’t and as I told her I started to cum.. He began to thrust wildly into my mouth as he let forth a great flow of his seed into my mouth. I swallowed it, savoring the taste in my mouth. It was the sweetest cum I’d ever tasted. Of course, I’d only tasted two, but this was the better of them. He groaned and closed his eyes as the last drops fell into my mouth. I licked him clean, then came forward to meet him. I kissed him and he whispered to me. ‘That was the best blow job ever.’ To thank me, he in turn laid me down and knelt between. "Lets head back to the room for some cold drinks and change into our swimmers before we hit the pool." said MomWhile Dad and I, as the losers, prepared drinks the women went off to put on their swim suits. A few minutes later they returned in just their bikinis and it was lucky Dad and I were behind the counter as I'm sure he was getting a hard on like me just looking at these women. Sue is a little taller but thinner than Mom. Her breasts are smaller but firm while Moms are large and round..
