Then tiff said she was cold then came and hugged me to huddle up but pushing her pelvis into mine. i couldn’t help thinking about it then my dick st...rted comin up. she felt it and said ‘is that cuz of me?’ with a little giggle i said ‘im not turned on by the trees’ and laughed back thinkin nothing of it when she said ‘im glad you decided to stay the night’ at that moment i knew i would be too. we went inside and tiff said she had to go to the bathroom. she came back out wearing only her robe. It was deserted but a car could come up or down any time. I began to ease into the situation a bit more now happy that they were happy and that they weren’t going to report me or anything. “Let’s see what you can do then sonny!” I must have looked like they were speaking in Russian or something as they both laughed at me. The taller one who’d not said a word did a ‘wanking’ motion with her hand and the other one looked at my cock that was now back at full mast. I was now going to give a show. What the hell he is doing at night with my mom? I stopped the taxi and paid him. As soon as I entered into gate I found mom parked her car at our parking lot. Both of them came out of the car. They were towards the lift and he kept his hand on mom’s ass. I became clear. Our apartment is at 6th Floor. I started to jump on stairs. I soon as I reached I found them coming out of lift hugging each other. Mom was opening the door and he was rubbing his dick on mom’s ass.Mom said – Come on we have two. That's the instant of the transformation. It's quick, a blink. We're hugging and laughing and we look each other in the face and I kiss her.We're not laughing. We're not saying anything. Her eyes grow wide, then she leans into me and we're both kissing, mouth over mouth, lips touching and brushing, sucking, breathing each other's air, our bodies touching all the way down. I can feel my penis start to grow between our bellies and I know she can too.Then we're not kissing anymore. She's stepped.
