Sam removed the bikini top as well to have a more clear look on the small hills that had formed themselves on his chest. Hstood in front of the mirror with one hand on his dick and the other touching one of his A-cup-size breasts as he saw the door handle moving. Not really knowing what to do he wrapped his towel around his hips like a sarong.
In the meantimed the door opened completely and a mother of about 30 years entered with a baby girl on her arms.
"Oh!" she said. "I didn't know that this room is occupied. But anyhow you should not be in here, young lady, as this is the family changing room. But as you are here you can also give me a hand with my daughter."
With this words she hold the baby girl to Sam and he instinctively took the small one. The baby mit herself comfortable at Sam's breast which gave him a very strange feeling.
The woman stripped down in order to change. Sam had to keep his eyes away as the stripping woman started to arouse him. She opened her bag to get her swimsuit out. She did not notice that while doing this a swim diaper designed for her baby daughter fell out of the bag. When she got her swimsuit out she stepped bag and by chance put her foot into the leghole of the swim diaper.
Then Sam came across a strange change. The woman shrinkecd in size rapidly. Her whole body lost its femnale forms until she became a twin to her baby daughter. When the chasnges were finished the new bay started to cry making her twin to join the crying.
The only thing Sam knew about babies was that they at least should be taken on the arm and comforted. So he manged to pick up the new baby without letting go the other one. Soon he had one baby girl in each of his arms. Both girls found their way to his breasts and started sucking. That gave Sam even more strange feelings. Unfortunately his breasts were thos of a teenager still in puberty. So he was not abke to breastfeed the twins. In one corner of his mind the thoughzt fomed that he vwas now responsible for this two girls. So finally he decided to try to become a mother to them.
The woman's swimsuit was still lying on the floor.
Sam placed the twins on the bench and made sure that they could not fall down. Then we let his towel go and took the swimsuit. He stepped into the legholes and slowly pulled it up to finally cover his whole body. After he made himself a little comfortable in this swimsuit his breasts started to grow until they reached a C-cup size. They became quite heavy as they filled with milk. The rest of his body change also to make him finally an exact copy of the girl's mother.
Samatha exposed her breasts and took the twin girls. Each one of the girls found one of Samathas nipples and started happily sucking. Samaha was overwhelmed with motherly feelings.
