At first, Trawn took a normal shower but then both Shawn and Trent realized they were in a new body. They started to explore their new body. The hot water combined with both libido's turned them on.
Trawn began to jerk off but Trent decided to do something else. He unmerged their upper bodies leaving Shawn playing with Trawn's merged genitals. Trent's upper body hugged Shawn's upper body from behind and played with Shawn's nipples. Trent kissed Shawn's neck and stuck his nose behind Shawn's ear.
Trent made love to Shawn while Shawn stroked Trent's cock.
Trent grabbed the shampoo and washed Shawn's hair. Shawn wanted to kiss Trent but couldn't. Then Trent's upper body began moving to Sean's front and they could kiss. Trent rinsed out the shampoo and moved down washing Shawn's back. Their lower bodies were till merged and facing the same way as Shawn so to Trent, his butt was in front of him and his cock was behind him but because they were merged, Shawn continued stroking their combined genitals while Trent took up massaging their combined butts.
They shot their loads at the same time enjoying a combined orgasm. They kissed but leaned against the shower wall, weakened.
They merged back into Trawn to dry off his one body but he kept their four arms to use the towels to dry off. Trawn then looked in the mirror to see what he looked like.
