Even in the rather concealing beachwear of the time, I could see that her body was nicely shaped and her breasts looked, as they would to any teenage ...oy heavily into puberty, very appealing, nicely rounded, soft-looking mounds flattened by the thick fabric of her swimsuit. When she lay out on her towel, face down, drying off after we had gone for a swim, she would pull the shoulder straps of her swimsuit over her shoulders to get some sun on them and then edge the top of the suit down to. It had felt so utterly awesome but did I want it to happen again? My mind just wouldn’t let it go. Dinner that fourth evening was a little strained with just the minimum amount of conversation. Finally, I could stand it no longer. “I need a bath tonight daddy.” I mumbled, keeping my eyes downcast, barely breathing. Face beet red. My heart pounding. I could feel my father’s eyes on me, still I refused to look at him. He put down his fork and cleared his throat. “Uh… Cynthia. We need to talk. “Actually, your thing in my butt! Do it now!”I got up and locked the door.“You want it? I hope you’re prepared for this!”She quickly shed her clothes and wiggled her butt in the air. That was a pretty clear sign that she was ready. I stripped off my clothes, grabbed the jar of Vaseline from her desk, and slathered it on my dick, stroking myself into a rock-hard erection. I rubbed some Vaseline between Katt’s butt cheeks, then put the jar down and got between her legs. Katt snaked her hand. I then decided to not stay in the patio- I opted to go inside and hide in the closet in our room. That way if anything went on I might get a better view. I cleared everything out and created my viewing spot.An hour later Sara came home and was alone, no son in tow, I could tell because she arrived and went straight for the phone in the living room down the hall. She called Brian and said, "Hey, the baby is at my sisters for the night. Do you want to come by and see me.?" My heart was pumping ,.
