You decided to walk around. A mermaid found you." So, do you wanna become part of the mer people?" She asked smiling. You considered, but at the last second declined." Too bad." She said smirking as she dragged herself out and grabbed your feet pulling you in as she forced you underwater. Except, you could breath. You began to get a erection as she pressed her blue tail up against your skin. It felt so soft. She rubbed her scales against your legs and you felt odd. Your erection began to sink inward slowly. You began to panic but it felt so good... You watched as your manhood pushed in and went inside as it flattened out. Your legs began to buckle and moved closer to one another as they began to bind. Your feet flattened out and became a fan like fin as your bones cracked and shifted. Your arms became hairless and nimble as they shrank to a feminine size. Your stomach sucked in and your hips widened as your rear became more lush and large. Red scales and Gil's began forming on your new tail as the mermaid forced your hands on the sand. She held you firmly down like a massive weight. Your brown hair grew longer and longer as your nose became softer and cuter. You screamed out but coughed, as your voice became high pitched and woman like." I almost forgot." She said grabbing a clam shell bra, matching your tail as she slipped it on. Your nipples became erect and pushed out like large balloons. You realized what you had become as she began to touch your tail slowly. She pushed up against it and rubbed. It felt marvelous. She swam up and turned to your old form and walked away as you lay on the sand looking at your nimble fingers. You felt your large breasts and sighed.
