I would do more than fuck that tight ass of yours.
First I would get it all prepped, wet and ready with my tongue while my uncut manhood grew to its full 7” length. Then once my cock was fully erect and dripping precum I would slowly work it into your tight ass.
As soon as I felt you were comfortable with the girth of my member, I would pick up the pace of pumping your prostate with my cock until I was ready to unload. Then I would grab that twink ass of yours and thrust my throbbing cock into your ass balls deep and unload.
After that if you hadn’t already blown your own load. I would proceed to go down on your cock. And start slowly licking your cock while inserting a finger or two into your sticky cum filled ass. I would continue to massage your prostate while my sticky load started oozing out of your ass. Then I would move down to licking and sucking your balls until your cock started oozing. As soon as your cock started dripping I would shift my attention back to sucking you off. Once you reached the point of no return I would deep-throat you balls deep into my mouth and continue to probe your prostate and pump your cock until I milked every last drop of cum out of it.
After that, and a bit of a rest you could return the favor if you wanted to. If you are ever in Atlanta Georgia area send me a message.
