And then I lowered my tongue in her clit she was damn wet I started exploring her cunt with my tongue circled her pussy lips and then went directly fo... her clitoris then there was no stopping she was fucking my mouth and I was enjoying she was going up and down and faster and faster and then after 15 minutes she came with a big oooooooooohhhh and orgasm she was half dead and as shivering.Now it was my turn she started to lick my penis from the soft fabric of the thongs I was wearing she licked. Sherry had barely got to us before I was at attention again.I've heard that some guys don't like to lick their own come out of a girl they just spewed it up, but I wasn't one of them. I didn't want any part of licking for another guy's come but I didn't mind having mine in my mouth at all, especially when I was sucking right out of the place I'd just put it.Stacy straddled my head facing her sister who was climbing aboard for her own ride about that time, and Sherry had her own tricks to pull. He was awestruck ... and clumsy. But he was polite. She didn't see him until her interest in her section of history was fulfilled ... then the 'interest' in the male of the species slapped her in the face. A visit from the future by herself to the past instigated the investigation. He was still at the school ... a newly minted Ph.D ... as she was ... he was working in his research lab ... she wore suggestive clothing ... one thing led to another ... ZAP ... they were married. She was so happy.. " I said jokingly as I kneeled beside the tub. "This could become a habit." Oh, please spoil me." She placed her forearms one on top of the other from knee to knee and rested her chin on the bridge they made. She was trying to give the impression that she was pouting and begging for sympathy."I love you, Mom." Oh, I know baby. But that's not the kind of attention I need just now," she explained. Her eyes searched the expression on my face hoping not to find hurt or disappointment.
