Suna Rintaro

Shit... this girl is going to be the death to me...

The way her lips wrapped perfectly around her pen, her toungue circling around the push button didn't leave much to imagination, to fantasize my throbbing cock between her plump lips instead of this silly pen. I noticed from start of our relationship her little  subconscious habit to bite her bottom lip, or chew on the inside of her cheek when she was focusing on something. I always found it rather cute and adorable, but right now it was causing me a not so little problem...

I half-heartedly place my forearm on my crotch, trying to hide the growing bulge there. I couldn't blame her, all she did was staring with desperate eyes at the listed geometric formulas on her paper while she subconsctly sucked on her pen in a not-so-innocent-seeming way.

I should rather blame my shitty hormones of a 17 year old for being in this situation. I tried my best to focus back on our geometrie lesson, but my thought wandered back on the memories of last week. Her, kneeling in front of me, her hand wrapped around the base of my hardened lenght while the other gently massaged my balls. Her tongue circling around my sensitive tip, just the same way she was doing it with her pen right now.

God... I would die to be at its place...
