She was as limber as his sixteen year old sister and even hornier. “There you go, Buddy.”, Aunt Robin said, “You got lots a room to work on me...now.”. Taking full advantage of this position, Brandon began plunging in up to hilt, pulling nearly all the way out then pushing deep again. “Ooooh, you’re way up in me now, buddy. Feel me squeezin’ you?”. He smiled acknowledging her muscle control.. After close to five minutes of vigorous stroking had been dealt to her by her nephew, Robin. I suddenly I was helpless; and realised what she intended doing!“No Iris please don’t...” I began whimpering.“Right my girl. I’m giving you a short flogging before I fuck you! It helps me get in the mood. I hope you don’t mind.” she chuckled.I groaned, yet much to my shame, my cunt was wet with anticipation.Then over her shoulder she called to someone, “OK Guy; you can come in now!”Horrified I looked up to see my naked son step into the room; ready to watch!“Oh God! No Guy!” I shrieked.Guy. I never have.”“Would you like to try?”“Now?!”“Yes, now.” He took my hand and placed it on his crotch. OMG, I could feel his dick through his pants and it felt enormous!“Well, won’t people hear? Or notice you’re missing from the party?”“Don’t worry, it’s pretty noisy downstairs and I’m somewhat of a wallflower anyway. No one will know.”“Ummmmm, I dunno. I wanna try, but I’m just a little nervous.”He unzipped his pants and my eyes went wide. I was scared, excited. He took out his dick and I. Perhaps he wasn't just her brother's nice friend. Perhaps he had really seen her, and apparently liked what he saw.She felt a warmth grow and pool deep inside her and her body began to relax and mold itself to his. He lowered his head to her and brushed her lips with his. She responded hesitantly. He kissed her, closed-mouthed and chaste for a few moments as he waited for her to be ready. He felt her hesitation melting and her body softening to his. He prodded her closed lips with the tip.
