You try

Cian takes of his top as your fiance opens his belt buckle she bites his lip and moves down his body kissing and nibbling every patch of skin she could get at loving his swollen pecs and glistening abbs. Her hands went down to his trousers as she was finished makeing out with him it was clear she was hungry for something else and she made sure to maintain eye contact as she grabbed at his crotch making him moan then pulling down his trousers exposing his massive 8 inch manhude and she loved it.

You wanted to look away not being able to stand your fiance jacking of this stud with such ferocity and joy laughing at you with every moan Cian gave but you darent look away for knowledge she had something worse to come. Eventually she got up saying back in a moment she came back "hey honey just thought i'd put on that lipstick you love so much" this made you grimace and almost look away but you kept your eyes on her as she wrapped her lips around the tip of Cians cock and swallowed all of his precum making him moan going up and down his cock. Stopping for air every now and then looking to you and saying "watch me take this cock down my throat" and sure enough you watched Cians entire rod dissapear into Sarah's mouth a feat she had never even attempted on you.

You could see Cian's entire body tense up he was close to cumming and Sarah new she kept deep throating his cock up and down until eventually Cian grabbed her hair and started fucking her face and to your suprise Sarah took it like a champ this started to make you hard seeing how talented your fiance was with a cock. Cian alerted Sarah to this she turned and smiled at you and looked back at Cian saying "facefuck me as hard as you want, shoot one loud in my mouth but the rest on my face I want him to see it".

Cian whilst staring right at you making sure you didnt look away grabbed Sarah's head and facefucked her digging his cock all the way down her throat making her gag and sputter with saliva all over his dick until his hips bucked forward and he shot one load down her throut making her cough and gag on it and then pulling his cock out sprays the rest of her face with his seed painting her face white with thick spurts.

This forces you to look away to the utter delight of Sarah who giggles at you running over to you she kisses you with her mouth full of Cian's cum and spits the rest on to your semi erect cock whispering to you "Because you looked away hes going to get what you wanted, he's going to fuck my tight ass and your going to watch or else" your whole body shuddered with these words and your cock became fully erect at the thought of her ass.
