Okay," Mom agreed, suddenly blushing as she glanced at me. She made her way through the room, heading for the bar, her breasts swaying and bouncing in...a very enticing way."Isn't she something?" Vicky asked."Oh m-my God!" I blurted, trying to control my nervous laugh. "I can't believe you got her to do that!" She's having a great time." I'll say." I was still stunned at my mother's boldness. She'd never been one for casual nudity -- it had been ages since I'd seen her in anything more revealing. While turning the corner and grabbing the stainless steel door handle I couldn't hold back the wetness that had overtaken my lace panties. Even my denim shorts had begun to dampen. "God, how does he always make me turn into a puddle with such ease?" I felt the joy and frustration of it hit me all at once just like it usually does when he makes me weak.Stopping as soon as I heard the door shut behind me to take a deep breathe and to make sure the room was vacant, I relaxed. Ever so softly I took. While he lay almost perfectly still, his legs just slightly apart, Gretchen was astride him, impaled upon his shaft and slowly moving her hips in a gentle rotation. Her head has bent forward, her hair hung like a cascading waterfall of reddish gold brushing upon his chest. Every so often she would lean down to kiss him or run her tongue down his chest, to his nipples which she would gently bite or nibble. Her hands were spread out before her, holding on to his which were spread straight out on. She asked me to clean the floor and spanked my ass while I was bending down to clean the floor. We started having fun outdoor too.We used to find a secret place where I can get naked and she used to click my pictures.Saturday night was the most happening day of the small vacation.She started the fun by pinching my nipples and asked to lie on my stomach and started spanking my ass and she even inserted a pencil in my ass and gave a nice hard beating till my ass was red af and she started to give.
