Yes

Becky swallows the pills, and I lead her back upstairs, she starts to fall forward and I catch her before laying her on the therapy couch. I had stuffed the Stethoscope in my pocket; and listened to Becky's heart for a moment. Then I opened her robe and took pictures of her perfect body. "So beautiful..."

I dashed back to the Med room and returned with a few things: a large speculum, a probe, two injections, a dental gag and three plastic mangoes. The two injections were for me and Becky; hers was to make her aroused, and mine was to make my manhood wider and thicker. I give Becky hers and take her pulse as it starts to work...her body becomes flushed in a minute. I take mine and my rod, becomes the width of my arm. Pleased, I make Becky's legs spread far apart and insert the speculum...it opened her wider than ever!

Using a penlight, I examined her vagina again as well as her cervix. Then pushed the probe, into her womb. Becky softly hissed and I removed it, and the speculum before inserting the mangoes. I did one at first; watching as Becky's muscles pushed it out...and stretching her vagina a bit. The same thing happened when I inserted the others...then I entered my sister with my new manhood.

As she had been prepped; I slid in easily. Plus, making a bulge appear just below her stomach. I use the Stethoscope to listen to Becky's heart as I went in and out of her at a quick pace. It was beating as hard as her panting. After a few minutes, I pull out and use the dental gag to open her mouth. "So pink...and perfect..." I thought, while sliding into her oral cavity. Her warm mouth enveloped me and I nearly came right then! I went in and out of her mouth before entering her throat...which pulled me down to the hilt. Her body was reacting to having me in her mouth and esophagus. "Good girl, sis." I say. "You're a good girl...I'll examine your body the whole time we're staying here...I'll know your outsides and insides! Hope you're ready...cause here comes the medicine you'll be having to take while you're here!" I shoot my seed straight down her throat and into her stomach, there was so much that her tummy became bloated. As I came; she had an orgasm. Not as big as mine through.

Once we were both cleaned up, I took Becky to her room and then kissed her lips. She moaned, and opened her mouth to me; allowing me to explore it with my tongue.

While I laid in bed, I began to plan the next medical check up's Becky would have over the next few days.
