She had on socks, blouse, bra, panties, and shorts. We boys had one less item than her, socks, t-shirt, jeans, and briefs. Laughing, Shirley said that...it only fair. She said if one boy lost, then all the boys lost. We all agreed to the ground rules. Shirley had won most of the rounds so far.On the first round Shirley lost and she removed her socks. She won the second round and we took off our socks. Shirley was on her third margarita, which is one drink above her usual.Boys lost the third round. . " was all I had to say. Monica unlocked Aaliyah's legs and I pulled out. Aaliyah was still coming down from her orgasm, but she slid herself back a few feet as Monica violently ripped the condom from my cock. She got a hand on my organ (I assumed she was intent on "aiming" my big finish), but I couldn't hold out any more and began ejaculating. My eyes were tightly closed in pleasure, so I had no idea where I was shooting, but I felt myself producing more cum than I had any right to at that. And then I noticed the two small gold rings protruding from each side of her labia.She saw me staring at her. "Is there something wrong mom?"I blushed at being caught staring. "Oh! Well no, not really... it's just that I've never seen someone who shaved themselves... uh... you know shaved their vagina. Although I've heard that young people do that but I never really understood why. Then there are those rings in your... your labia, why in Gods name would you have yourself pierced?"She looked at. She said, “Walter, I cannot do much to find a girl for your younger brother but I suggest; a gift of having 3some sex as him being a third partner. No other gift could match the value of you offering me to him for satisfying sex and show him, how close you took him to your heart”. As I said, sure it was a weird suggestion but I did not consider it such. I did not even think that Scot had never seen me nor have I ever seen him naked before and it would not be easy for me to fuck Natasha or him.
