The bulge in his boxers was getting bigger and when Rosanna pulled them down I nearly gasped as the sight of his cock. Not even fully erect it was about the length of a ruler and as thick as my arm. Rosanna stroked her fingers along his shaft and around the tip and it soon was fully hard. Even longer then then a ruler now I would say.
Rosanna slowly pulled down her panties and seeing her shaven mound I could feel my cock was getting hard. Don took a condom out of his trousers and rolled it on then they hugged each other with his erection pushing against her stomach. She slid her hands onto his firm bum and stroked it as he kissed her neck.
Rosanna then let go of Don and said “Put your meat inside me”. She looked over at me and I smiled then she climbed on the bed and I glimpsed her pussy which was glistening. Getting on all fours and positioning herself so I could watch her side-on Don got on behind her. Taking the tube of lube off the bed which we had left there he spread it all over his cock. Then squeezing more on his finger he smeared it against her bum hole then slowly pushed it in with his finger.
Rosanna let out a gasp as his thick finger entered her bum and as he moved his finger about to spread the lube and stretch her bum she moaned more. Taking his finger out he put his mushroom sized tip against her bum. Wondering how it could possibly fit he began to push it in. Rosanna cringed in pain as about half of his tip disappeared into her bum. Unable to get anymore in he pulled back then tried again and this time most of the tip penetrated. Then with one more push the tip slid in and Rosanna let out a cry of pain.
Don then began to ease his thick shaft in inch by inch. I saw a tear running down her cheek and said “Do you want to stop Rosanna?” but she replied “No way”. After more pushing and easing nearly all of his huge cock was inside my fiancés bum. Don while holding her hips firmly began to slowly thrust in and out. Rosanna was moaning with discomfort as her perfect little bum hole was being stretched to oblivion by his monster cock.
My cock was now straining against my trousers and I would have to free it soon. As Don began to speed up his thrusting I could see Rosanna was now enjoying it. Her moaning was now due to pleasure and she actually looked over at me and smiled. Watching his cock sliding in and out of her bum was so thrilling I just had to jerk off. Unzipping my trousers I pulled out my seven inches from my boxers and began to pull up and down.
Pre come run down my tip and onto my hand as I jerked away. Rosanna meanwhile had took one of her hands off the bed and had slid it between her legs. I could see she was rubbing her pussy quickly and was moaning out loudly with almost every breath. Don has increased his thrusting rhythm and was practically pounding her bum. His groin was smacking against her bum cheeks making Rosanna’s body wobble each time.
My balls were tingling with excitement and currents of pleasure were coursing through my body. Rosanna tipped her head back and with her hand now rubbing furiously over her pussy she started to shake then she shouted “I’m coming”. Rosanna then screamed as she came hard to a thunderous orgasm. Don stopped thrusting until she got her breath back and stopped shaking. Then he carried on.
