There I stopped for some moments as if to give him a sensation that I was going to fuck him.Then I descended further. Guiding his cock-head with my ri...ht hand, I put it just at the entrance of my dripping pussy.I groaned, "AAHHH, AAAAHHHH...AAAAAAHHHHHHHH ....... AAAAHHHH", as I descended, slowly but steadily, more and more upon his cock. The tip of the cock began to enter in to my love-tunnel slowly, very slowly, spreading tight muscles of my pussy. Love-juice began to spring from the volcano. I squeezed my eyes shut, both wanting and fearing the smack of flesh.My tongue licked.My sister groaned, shuddering, as I lapped through the tangy folds of her pussy. Her eyes lit up with such delight. Her small breasts jiggled as I tasted her juices. As I felt her hot silk on my tongue. I licked again, my ass still burning, the heat radiating into my pussy, boiling it.My tongue danced through her folds. I couldn’t stop myself. I was licking her pussy like a filthy dyke.

I reversed my direction and started sucking her breasts as I used my hand to gently message them. Elizabeth by this time was licking Louise's slit with her long tongue. As Louise became more aroused, she began gasping when Elizabeth touched her G-spot and her clit. With a strangled moan, she stiffened and climaxed.Pulling Elizabeth to me I kissed her, tasting Louise's fluids on her face. Louise then pulled both.
