Then I circled my tongue around the head of his cock for awhile.Next I put my lips again gently on the head of his cock.I didn't suck I just moved my mouth like a fish very gently. The head of his cock was growing rapidly as was the rest of his cock.I continued this for a longer time because he was squirming and I knew he was going crazy not to. Sarah has some ham and cheese and some other stuff for sandwiches. Hurry upstairs and change. I have your clothes on the bed.
