My word would have been enough for them to see the error in judgement they had made in allowing this dangerous young Woman back inside school grounds....et I’m ashamed to say the humiliation of the way she was treating me had my pussy more than tingling, in fact I could feel a wet spot had started to form on my underwear such was my arousal at being treated so poorly by a schoolgirl. I could only whimper beneath her as I allowed her to dominate me. She removed her sandaled foot from my cheek. All I wanted was to empty my cock in her. When my balls were about to release Liz's hand grabbed them. Not enough to do damage, she wanted me to know I was not going to incriminate my sister again tonight. I pulled out quickly so Liz would let go. "Get on your back" Liz likes to control things sometimes and she was in full character tonight. She slowly sat on my face and started playing with my balls. Liz and Linds both tortured me. A stroke or two, a nip, a lick, a quick suck all took. She warned us not to be late, but I didn't think that would be a problem. Vince had budgeted plenty of time for this. We went up to my bedroom and I started taking my clothes off.When I was totally naked, I lay down on the bed and put my feet in the air. Vince found the lube on my dresser and began working it into me. I closed my eyes and enjoyed the pleasurable sensations of his fingers exploring inside me. He pulled them out and replaced them with his dick. I groaned in ecstasy as Vince. Robby's dad picked it up and it was my mom, saying I needed to come home for lunch. After saying our byes, Robby and his dad took off. I decided to take the shorter way home, and cut through their backyard. I was walking around the side, and soon as I turned the corner, I thought I had reached heaven.Standing there, apparently watering the plants, looked to be a goddess; Robby's mom. Although I was only about 13 or 14 years old, she had been the subject of my "stroking sessions" for many.
