She began playing with her pussy as a display for the couple who arrived earlier. They responded by coming over and laying their towels down beside ours. We didn't introduce ourselves, instead just smiling and nodding, acknowledging they were here for the show. She was about our age, average body and very well tanned without a hint of lines so she was obviously a frequent nude sunbather. He was a bit younger; her toy boy. Quite fit, larger than average cock that was rock hard from watching our display. They both lay on their side facing us, him behind her, with his arm over her hips playing with her pussy slowly.
My wife lowered the leg beside them so they could see her fingers rubbing her clit. I positioned myself between her legs and spread them slightly so I could get a good view of that wet cunt. I lowered my head onto her and kissed her clit. She arched her back, lifting her hips to my face. She tasted so sweet and was as wet as she'd ever been. I slowly licked the length of her pussy lips, up and down along the outside of her cunt, gradually getting closer to the hood covering her clit. Now and then I darted my tongue inside her. As I moved my focus to her swollen clit, I slid two fingers inside her. She grabbed her thighs to spread them wider, lifting her knees up to her chest and raising her hips. I responded by moving down to her asshole and licking her pert butt hole.
