She slowly slides it into your ass

This catches you out completely and you penis is fully in Abbie as you stop and become accustomed to the new sensation, as the dildo slides further into you ass. Before you know it there is 8 inches up there, this sensation gives you the greatest sexual feeling you've ever had and encourages you to fuck Abbie even harder than before. You continue fucking Abbie until you can take no more and proclaim

"AAAHHH!! I'm gonna cum!" at this point Abbie rams the dildo up your ass, just as you pull out and cum burst forth from your dick coating Abbies tits and face in a thick layer of creamy cum. You knees become weak from the intense orgasm as you look down at Abbie and see you cum beautifully lathered over the sexy woman before you.
