For a moment she had almost forgotten about it, but that feeling of nervousness returned immediately and soon turned into a shiver all over her body.

- Oh my God! But is it necessarily?

- Sure, if they gave me two, you'll need two!

- Come on, don't make a fuss that we're done in a minute!

She went to the other side of the bed, already holding a syringe and a new wad.

She placed the syringe on her friend's back and gave her a gentle massage on the buttock to disinfect and anesthetize the part a little.

As soon as she heard the massage finish, she stiffened her butt with fear, but less than a second passed before her friend gave her a loud spanking on her bare bottom!

-OUCH Giulia! Are you stupid??

-Ahahahah, relax that ass! If not, you feel even worse!!

She said laughing.

With a little more courage than the first injection, she took the syringe and after having carefully targeted the place to puncture, she inserted the needle into her friend's ass.

She tried not to complain about her friend's lack of delicacy, thinking that it was also the first time she was making an injection!

Giulia, not seeing Ilaria complain, safely grabbed the plunger and began to vigorously inject the liquid.

Sara felt the fire in her ass!

- OUUCCHH !!! It burns !!! Slowly please!

Giulia seeing such a broken reaction from her friend suddenly left the syringe!

- Does it burn that much?

- To die for, but what's in this drug?

- I don't know when my sister gave them to me, it hurt me a little, but I resisted!

- Try to resist, I'll inject it slowly!

Giulia looked back at her friend's ass, who in the meantime had remained there with the syringe still half full of liquid planted vertically.

She hesitated a moment before grabbing the plunger again. Ilaria's ass today had a different effect on her, she was looking at it with different eyes. The injections, that little spanking, having dominion over her at this moment was different!

The torture resumed. Giulia pressed very softly but Ilaria couldn't help but suffer.

For about twenty seconds it was a whole scream of pain that ended up sending her two big tears!

- All done!

Giulia said pulling out the needle.

- Finally, what a pain !!

- Give me a nice massage this time please!

Giulia placed the syringe with the needle still uncovered on the bedside table, took the cotton swab she had just used and after placing it right at the injection site she began to slowly massage her friend's ass, making it slightly sway.

She kept looking at it in silence.

Sara, however, was unable to calm.

-My God, tomorrow this suffering again!

-Tomorrow I will try to be a better nurse, but now relax, in a little while you will be better, much better. Trust me.

Continuing to massage her friend's buttock, she bent over on her friend and began kissing her bare back.

She did not know what she was doing or why she was doing it, but she was extremely excited…

Sara began to breathe slowly, a shiver of pleasure ran down her spine.

Slowly she began to spread her legs, discovering all her intimacies for her friend inviting her to continue.

Giulia continued to kiss her back.

Her hand slowly disappeared between her friend's legs.

.........The end...........
