And I slowly moved down to suck on her pussy. Out of the corner of my eye I could see "K" her husband stripping off and holding his shaft in his hand,...wanking slowly, at this point she stopped sucking my cock and pushed me away, I looked at her with a questioning look, she smiled and removed all off my clothes. The three of us were there now totally naked and ready for the fun to begin. She beckoned her husband over and got him to lie in the bed and straddled his face pushing her erect clit. She loved them both mightily and differently.She let the hot water rinse the remaining shampoo from her hair and body. She stepped from the shower and grabbed a big fluffy towel. Vigorously she dried her hair and body. She lingered briefly on her clit. The soft roughness was almost like Sam’s tongue. She mentally shook herself. Behave, she thought laughing!Jamie reached for her worn Terry cloth robe. She hesitated. Then she rummaged through her closet. She found the pink satin robe she was. She slightly moaned and I said, “that was an amazing experience, how do you know exactly what to do with me?” She replied, “This research helped hone my skills I already had from my married days”. She then relayed her time with her husband and how she lost him to cancer. That is why she wanted to do projects like this, it is to help figure out what can be done to keep the prostate healthy and many believed a active sex life was the key.She then said “…let’s not talk about this anymore, it. She then took off her shirt and grabbed one of my black t shirts and before she could put it on I muttered god dammn s*s.. she laughed a lil and said what. I said you are so sexy look what you did to me.. looking down she saw my huge cock bulging in my pants. mmm she replied as she grabbed it and started rubbing it outside my shorts. she then said to me, do you like looking at your sister in her underwear. speechless I said only of course, so she said really, and walked away to her room.
