Smuts 4 Dayz!

Cotton Candy(RvB Caboose x Donut):

Caboose and Donut were all alone together in the caves. They had meetings like this every Saturday night so they could be themselves. They would take off their armor and make out and cuddle. This night, however, Donut was feeling excited. This was the night he would convince Caboose to have a little fun with him...

"Hey, Caboose?" Donut asked.
"Yeah, Private Biscuit?" Caboose replied.
Donut blushed as he braced himself.
"Caboose, how would you like to have sex?" He asked. Caboose thought for a moment. He didn't remember ever having sex or what it was.
"Explain what 'sex' is?" Caboose said. Donut gave him the talk for homosexual men.

"Well, if it's not going to hurt, I guess we can do that." Caboose said. Donut was overjoyed. They were finally doing this!

Donut pulled out some lube. They were going to need it. Donut began grinding his hips against Caboose's. Their hips met, they moaned, and their members got hard.

Donut and Caboose were now completely nude. Donut rubed the lube up and down his lover's dick.
He then raised himself to straddle the blue. He let his ass envelope Caboose's large cock. They both moaned loudly. Donut then moved up and down. Caboose began thrusting upward fast.
"Oh, s-so you like it rough, huh?" Donut said, moving harder and faster. Caboose grabbed at Donut's dick and began pumping. They were both coated in sweat.

"C-caboose! Ah! I-I can't hold it anymore!" Donut said before cumming all over Caboose's hand. Caboose wasn't that far behind. He filled Donut's ass with his semen. They caught their breath.
"Next Saturday, let's do doggy style, okay?" Donut asked.
"Okay." Caboose panted...
