The Doctor sipped some of the water from his hand, he knew that there were some very powerful endorphins in the water - the result in making humans incredibly horny.

He turned to look at Rose, who was now very aroused and starting to strip. It was then he realised the hormones were effecting him too, and he could feel his cock starting to twitch.

Rose was now wearing just her bra and panties, the rest of her clothes being discarded on the floor. The matching black lace underwear barely concealed her gorgeous body. The Doctor could clearly see her hard nipples and bald pussy through the lace.

The Doctor watched the striptease with increasing excitement.

As Rose finally finished stripping, and was now naked, the Doctor started to undress. As he removed his clothes, Rose leant against the cave wall, and slipped two fingers into her already wet pussy. Her other hand tweaking her hard nipples.
