With my still erect cock in my hand I started to push against her rear hole and she screamed in pleasure. “Jack you want to fuck me there? Go on the... fuck my dirty black hole and don’t hold back”I started to enter her ass and it was tight she winced as I ploughed her dirty hole with full force she sucked my cock back in as it was held in there like a vice gripping every vein. I touched her hilt and she started convulsing again and again I felt the wetness dripping down my thighs. This turned me. Now I was standing in just bra and panties, waiting to be stripped by someone else.That didn't take long as I saw Mistress nod her head and my bra was being removed. It was a boy, who slowly undid the hooks one at a time. Sliding his hands around to cup my tits. Using his tongue to slid the strap off my shoulder, till it fell to my elbow. Then he did the other arm the same way. In the process leaving a wet trail down each arm. He told me to hold my arms straight out, as his fingers slid under. " Mmmm-mmmm." Soon I begin to pump my fingers once again, pulling back then pushing forward all three fingers at once. The sensation of her two holes being simultaneously fucked like that causes Ahn to moan around my now completely hard cock, causing her hips to rock and push back at the assault. " What a sweet ass you have," I grunt behind her, my fingers pumping at her backside. " You ever have a hard thick cock in this sweet ass, Ahn?"The question causes Ahn to tense up as she realizes the. .I mean, I...I don't want to get in trouble." She looked right at me when she said it."Oh no. No, we're not going to do anything stupid. Just some fun stuff for a girl like you to know about and be able to hang with guys and not get in trouble. And, you know, you don't want to be just be a little tease." The pretty teen just smiled in response.So, late that night, after barbecue and beers, I heard Mary quietly making her way down the stairs. She actually tapped lightly on my bedroom door before.
