I stuffed my panties in my mouth to muffle my moaning so no one would hear me as Frank continued to stroke the inside of my pussy with his large cock.... Frank’s cock was so large it pressed hard on my g-spot and the way he stroked it moving slowly back and forth made my body tremble with pleasure. I took my panties out of my mouth and breathlessly said “if you think I need to orgasm just say ‘cum’, but if you don’t I will restrain myself”; then I stuffed my panties back in my mouth, leaned back. I warmed up with some shadow boxing, and Wendy headed right for the treadmill. Her legs were already warmed up from our bike ride to the school. I stretched on a nearby bench and gave Wendy a wink before starting on the incline bench machine.The time went by, and I was headed over to the bicep curl machine when Wendy ended her treadmill walk. She came over to plant a kiss on my sweaty forehead."I'm off to the little girl's room." Okay. I'll be here."She trotted away on her strong legs and made. Kelly took me out of her pussy, took her tongue and licked down my body until she reached my cock. She started sucking and licking her own cum off my cock. Kelly then stopped, she got on her hands and knees. “Come and screw me doggy style Jeff I like it like that way” she exclaimed. I got up behind her, inserted my cock into her slowly, and then started to fuck her. She yelled out “Oh yes, oh god yes, oh fuck my pussy, oh fuck yes, oh fuck, fuck, fuck yes, oh god fuck I’m cumming again,. Boy, if she heard what’s been going on in here! I walk in on you fucking the shit out of my brother. Looks like lust for him runs in the family.”I puzzled the last thing he said, and he went on, “I’ve been fucking your Uncle Tony for a long time, Josh. You must not know; he lives just a few counties over now. Where did you think I was going all those times I told you and your mother that I was going bowling or golfing? Nah, I just drove over to his house, and we did the exact same thing you.
