I have no idea just what time it was when Dad and Sue arrived back home for the second time that day. I only know that Mom and I were not there, we were out riding far from the ranch buildings. It wasn't until after Mom and Dad went up to bed late that evening that Sue and I had an opportunity to discuss the days events. Shortly after they left the room and went up to bed, we went outside, stripped and climbed into the spa. There, Sue related her adventures with Dad that day after they came back to discover Mom and me screwing our hearts out on the patio. "God Jack, that was so hot, stepping onto the patio only to see you humping Mom the way you were. Made me want to jump Dad's bones right then!"
"Anyhow," she continued, "after leaving you and Mom the second time, Dad drove on in to the building supply place where they quickly spotted just what was needed for that back splash. The purchase went quickly and, with help from store employees, the item was loaded on the pickup. Since it was hot, Dad stopped at an ice cream store where he splurged and had a banana split while I only had an ice cream soda." Sue grinned when she told me, "I really think Dad hoped the ice cream would cool some of the thoughts he was having about you and Mom and what he was hoping I would do with him. I guess it worked too, at least 'til I got him out to the creek once we got back home again."
As it was, Mom and I must not have been far away when Dad and Sue returned. Not finding me, Dad decided to leave the large sheet of fiberglass in the truck until I would be available to assist in getting the thing around back to the patio. After checking the patio and spa, Sue told Dad it was too hot to even consider getting back into the spa and they decided to go for a swim instead.
I guess swimming was Dad's idea because Sue says she teased Dad that he just wanted to see her naked. She says she also told him she wanted to try a little of what they caught Mom and me doing. I guess Dad only offered up token resistance and Sue says she located a couple dry towels and they walked to the creek where they stripped and swam for a while before stretching out to dry off in the sun.
The way Sue tells it, she had to initiate sex with Dad although his reluctance waned quickly as she played with him. At that, Dad may never have done more than kiss her if Sue didn't take the lead and direct one of his hands onto her breasts. After that, she really didn't have to force Dad's mouth to her breasts, she only had to thrust a breast close to his mouth and let him take it from there. While suckling, his free hand made it to her pussy all by itself, she says but, at that, she had to press on the back of his hand to coax one and then more of his fingers into her vagina.
Once his finger was wet with pussy juice, Dad needed but little additional encouragement from my sister and took the lead, receiving only gentle suggestions as to what more she wanted him to do. Whatever inhibitions Dad may have harbored about an incestuous interlude with his daughter must have been easily suppressed!
Sue says that once she began stroking Dad's cock, there never was question in her mind but that she was going to get fucked. She giggled and told me she nearly chickened out when she realized just how big Dad really is. She apparently suppressed her concerns about not being able to stretch enough to accommodate Dad's cock, convincing herself that if she asked him to stop it would have been all over with.
Whatever, Dad managed to show my sister just how much stamina he has. She says that she wishes she had been wearing her watch because she's convinced that once he penetrated her, he brought her to at least three explosive orgasms over what must have been a twenty or thirty minute interval. She says that had she been able to continue, she's sure Dad would easily have kept on fucking for a while after he filled her with cum. I doubt that but wasn't there and don't really know if Dad can resume fucking so soon after having an orgasm. She says she had to beg Dad for a time-out so we may never know just how much stamina Dad has.
When Dad finally rolled away from her, he stretched alongside my sister and they embraced for a while with her nuzzling against Dad's neck. Then he nuzzled her nipples for a time, apparently teaching her what it would be like someday when she had a hungry child or two to take his place. I guess Dad didn't understand, I had already done that as had Eric and Pete. I imagine she has the picture now, although I'll try, on occasion, to see she doesn't forget.
Later, after resting and cooling off in the creek again, Dad had Sue assume a position on her knees with her head on her folded arms and took her from behind. She giggled telling me about it because it sort of made her feel like some of the animals around the place we have watched copulating. Whatever, it was while taking it doggy style that Sue says she was sure she heard something and thought she felt the presence of something or someone besides she and Dad. By the time she could lift and turn her head to look, she saw nothing out of the ordinary and still doesn't know if someone actually saw them or not. She's guessing it was some of the Peterson clan who beat a hasty retreat when they discovered what was going on. If it was, I have no doubt we'll hear about it eventually.
Anyhow, I guess Dad heard nothing as he continued bucking and thrusting into my sister's upturned pussy and, eventually, spewed another load of cum into her again. Sue says they rested and swam again, but that Dad was pretty well done in after that second round of sex. Not to the point of being incapable of cumming again though as Sue says she went down on Dad once they were out of the water again and surprised both of them when she got him to ejaculate again. She giggled and related how handily she was able to take Dad's semi-hard cock into her mouth and how she hoped he wouldn't achieve full erection and get back into her throat. She giggled again and admitted she wasn't about to give up trying though. Her look was dreamy and hot when she said, "Someday, if I keep trying hard enough, Dad's going to fuck me in the mouth without having to worry about choking me to death."
After that, we embraced and enjoyed the hot water in silence for a time after Sue announced her intention to practice her cock sucking skills on Dad until he could fuck her mouth easily. Actually, I was working on how to let her know she was welcome to practice on me whenever Dad wasn't available or was busy with Mom. I never did get the words out however, Sue beat me to it and said, "If you'd like Jack, I would be more than happy to practice on you too. Right now if you'd like as I imagine it is a skill that takes a lot of practice before one gets it just right. One thing though, I don't think we better try to have sex the regular way, I'm way too sore from fucking Dad this afternoon."
Knowing that my sister wished to keep her groin in the soothing hot water, we decided I should sit on the rim of the tub and she would kneel and do me, keeping her butt in the water. At that, she knelt before me in such a manner that I was able to massage her pussy slit with one foot while she sucked and stroked my cock.
Guess I'm not quite as large as Dad as Sue managed to take more of me into her mouth than I would have expected. While it would be a while until she achieved a Linda Lovelace skill level, she did really well and had to quit when there was only a little over an inch to go until she would have her nose shoved into my pubic hair. Since it was early in Sue's oral experience and I didn't wish to cause discomfort, I let her do all the work. Which is not to say I didn't have an almost overpowering inclination to steady her head and meet her head bobs with mighty thrusts of my own.
Unfortunately, I wasn't able to hold out long and my cock quickly swelled, giving physical warning of impending orgasm. I guess I could have staved off the inevitable had we paused to let the familiar sensations subside but Sue was having none of it and continued bobbing her head up and down and sucking until I erupted while deep inside her mouth, almost all the way into her throat.
