Feeling that we wouldn’t get caught, we parked behind a berm of landscaping and wandered off into the park. Kisses grew more fervent and soon we wer... shedding clothes and kissing and licking every newly exposed inch of skin. She was hot and tasted both sweet and slightly salty. Kara moaned as I kissed and licked my way into her inner thighs, and then slowly ran my tongue up her from her ass to her clit. Grabbing my head, she pulled me right into her pussy and shuddered through her first orgasm.. I watched a slight glow of red flare up her neck from her open shirt and on to her face as she stammered a bit, and finally said, " well there is a problem, and I was sort of hoping you could help ". To calibrate the equipment, I need to establish a base line, and that requires human semen." I just smiled, and said " there must be lots of men who would just love to help you with that project." She blushed again and said " yes, you are right, but what I really need is semen that does not contain. It was a tiny room, but it served its purpose well.An hour or so after breakfast, I was pulling clothes from the dryer as the ones in the washer finished. I was bent over reaching into the dryer, when I felt Don push his crotch against my ass. I wiggled my ass into his groin. I stood and put the dry clothes in the basket on top of the dryer. I turned to him. My mouth watered just looking at him.He was wearing a pair of his cut off sweats and a t-shirt with the sleeves cut out. The hair on. The next morning she tells us she has business in Singapore and will be gone a couple of days. So we take it easy. We sleep in, then go down to the beach and sleep some more in between dips in the ocean. We did not know it until now but we are SO jetlagged! We spend only some of the night sleeping but next morning, we are well-rested. We decide to hit some of the local historic sites and museums. We’re feeling really brave so after lunch we buy ourselves a durian. The stink is everything all.
