I will enter her slowly, I want you to be there, kiss her while I am entering her
You sick on her left nipple and I will suck on her right nipple at the same time while I am inside her
I will hold off cumming until she comes, after I pull out of her you go next immediately before she can object to it.
She will be stretched out a little but the sensation of my cum and her loose pussy will be amazing to feel. When she starts to close in around you you might cum on the spot.
