Debby started to blush from her brother’s words. “I like it too Jake… Spending time with you, us together, It’s relaxing for me.”
They looked at each other for a little while before Debby spoke again.
“Alright, why don’t you start with some lightweights and warm your arms up while I get rid of this sweater. I’ll do some warmups myself because I don’t like helping you out while my body is a little cold.”
“Fine by me, we got enough time so do it at your own pace.” Responded Jake while working out his arms with the use of small, lightweight barbells.
Jake watched his little sister close after she got rid of her sweater. She was wearing very tight gray yoga pants that hugged her fit lower body perfectly. Every time she bend over to stretch he could easily see her pussy outlined, his sister was displaying one hell of a camel toe. From her top he got pretty much the same effect. A short gray matching tank top that showed off her firm small breasts and their cute tiny nipples. They poked against the fabric so it was pretty obvious that she wasn’t wearing any sort of bra at all.
“Ah, that feels much better… So big brother, ready for that arm training?” Debby asked while standing in front of him.
“As ready as can be Sis!” Said Jake.
“Alright, I want you to sit in the middle of the bench so I can help whenever needed, here, let me help you with your legs… Good, okay just start the exercise routines that I made for you.”
The following half hour was filled with all kinds of exercises to help training Jake’s arms, Debby was so proud of her brother that he never gave up on it, her carefully made routines had really helped him to develop strong and muscular arms that could support him wherever he needed.
“Worked up quite a sweat, didn’t you big brother?” Asked Debby as she took the heavier barbells from him.
“I did, but for a good cause! Your exercises really help me a lot Deb, I can’t thank you enough for spending all that time on making them for me.”
Debby blushed again. “Like I said, anything for my sweet brother!”
“Speaking of exercises, how about a final one? One to end our session today.”
“I still got some puff left so why not? I’m game!”
“Okay!” She said excited as she started to straddle her brother’s legs.
“Whoa Sis, what’s up with this?” Spoke a confused Jake, his little sister now a few inches away from him, sitting on top of his legs.
“So I can keep an eye on you closely, to make sure you won’t cheat!”
“Okay… So some sort of competition? Do I get anything for it?”
Debby was thinking to herself when she started to blush and giggle.
“I was thinking… For every ten seconds I will give you… A kiss!”
“A kiss?”
“Yes! Instead of ice cream, like my bet, I will give you a kiss. Or would you rather have ice cream instead of a kiss from your sweet, cute little sister?” Said Debby with a cute pouty face.
“N-no a kiss is good with me; how could I resist an offer like that ha-ha!”
“Yay!” Yelped Debby before giving her brother a tight hug.
“Alright Miss instructor, what do I have to do?”
