Oral and your transformation

You let go of Stacy's head, you expected her to surface, spluttering like you normally did after transformation. Instead, you felt something move over and envelope your cock. Your sister was giving you and underwater blowjob. You felt her lips rotate around your cock as her whole body moved over you until you found pink scales in your face.

You bend your knees as you felt her hands on your waist pulling you more towards the middle of the bath. You grasped her hips and pulled her tail over you until your mouth was lined up with her pussy where here scales and skin connected. You had done this with mum before, a mermaid's pussy was not a cleft between legs but a hole in which you could snake your tongue inside. From this angle as the sides of your tongue parted her lips the base of it rubbed against her clit, pressing down on it as you **** your way deeper finding the opening to her vagina.

You could feel her tail squirm over your face, her smooth pink scales dominating your view. You felt her tongue tease the shaft of your dick as the tip rubbed over the spongy back part of her tongue, close to her throat. Then you felt the tip of her tail press against the back of your head and her hands pull on your hips. Your face was pressed hard into her sex as her body rotated. You used your grip on her hips to help her pull you around until you were on top of her. The tip of her tail pushed you down into the water and held you there. Her tongue worked hard on your cock as you began to drown in her pussy.

But you wouldn't drown, you both knew that. Instead, you embraced the transformation. As your turquoise scales began to emerge and your legs fused you continued to eat out your sister. You thrust your hips as your tail finished forming and came down your sister's throat. You felt her tail still holding you down as you felt her lips move up and over your cock having swallowed your load it seemed she wanted you to finish your side before she would let you go.

It did not take long as you blindly groped up towards her chest and cupped her breasts. You found her nipples hard and blindly pinched them. All the time delving your tongue in and out her pussy to rub back and forth on her clit.

"Oh Yes!" Stacy screamed as you felt her pussy squeeze your tongue.

Then her tail finally released your head and you came up for air, the taste of her sweet juices still in your mouth.

"Ah" you gasp as your had surfaces. Well, that is one way to have me transform.
