Next time did take your shirt all the way off . She is blowing you. Show her some gratitude for her effort and get all the way naked as males should be.
I used to tell my wife to find guys with big old cocks and bring them home occasionally she would and I wish I felt the same way now as I did then because I probably would have put my lips on it too. During a couple of threesomes my life would go to the bathroom or something and I would laugh a guy f****** go down on me without her knowing now I would do it in front of her which I do but it's a new wife
beauty how she enjoys giving a good blowjob...
