I had to write to tell of the wonderful treat my lovely wife Anne gave me last night-her tight little arsehole. Anne is 10 years my junior at 36 and she is lovely with brown hair and eyes and a womanly figure that has become all the more astonishing since becoming pregnant. At 6 months now her breasts have swollen from a 34d to a g cup they are like 2 ripe melons and i love to caress them. Anne and i have always enjoyed an active sex life and even in pregnancy Anne still offers me relief whilst normal lovemaking is less on the cards. I don't mind at all-Anne will sit up in bed and take her nightie from her shoulders reveaing her fantastic big big tits whilst she wanks my engorged cock causing great spurts of hot come-bliss. However i had a really nice surprise last night- as we snuggled Anne with her back to me she began pushing her bottom against my erection and said- 'Darling would you like to put your cock inside my bum? I know you would'. I was shocked-Anne had always refused to do this before saying that my cock was too big or it would hurt or it was a dirty/dangerous thing to do now it seems her hormones had produced a new and very welcome craving. 'But dearest are you sure you always seemed so against it' i said. I have fucked my ex wifes arse many times and i must say i had yearned to take the same liberty with Annes virgin backside. 'Yes darling i wan't to feel your big cock up my bottom' Anne replied. Within minutes i was lifting her nightie as she lay on her side as i caressed her buttocks i told Anne i was going to give her a big thrill but it would probally hurt a little-Anne replied that she wanted it to and that she wanted me to use her for my pleasure! I wasted no time in lubing her arse and ordering her onto her back. Her legs raised to her chest Anne looked apprehensive as i placed my cockhead at her little pink pucker. 'Oh darling please be gentle your cock is so big.' pleaded Anne. 'I am going to fuck your arsehole my dear and it will be deep and it will hurt and you will love it' i said getting into my role. 'AAAAAhhhhh! OOOOOOhhh!'cried Anne as i put my big cock head and about 2 inches of cock into her incredibly tight anal passage- slowly but surely i treated her to all 7 inches in her bum and boy did she love it. 'Oh darling it feels sooo big it really hurts so good ooohhh ooohhh '. I was in seventh heaven as i told my darling wife about how much pleasure her tight rectum was causing my engorged cock. By now Annes nightie had been lifted clear so i could view her big milky tits-hairy pussy-and cock filled little arsehole. I told Anne i was going to spunk right up her bum and this precedented her own orgasm. I have never heard Anne make as much noise as she did as i emptied my aching balls in that fucking hot tight anal passage of hers. Anne and i showered afterwards and later in bed told me she had conquered her fear of arsefucking and that she'd do it again sometime but not now as her poor bottom was much too sore after it's deflowering.
