I think she must have felt the change in my groin, too, because I saw her eyes boring into my crotch.
"Would you like to see it?" I glanced at my nearly bursting jeans.
Irina nodded shyly.
I unzipped my pants, revealing my swollen testicle. It's hard to describe Irina's expression at this moment. I'm not sure if she's shocked, afraid, or excited.
"Did it scare you?" I asked.
'I didn't realize it was so big.'
"You can touch it. It will like you."
Irina held my testicle gently in one hand, then let go and made a circle with her thumb and middle finger, telling me, "It's this thick."
I led her hand to my testicle and showed her how to play with it. I continued to kiss her neck and her collarbone. Her panting grew more ragged as my other hand touched her soft breast.
I lowered the seat back. She leaned over me and kissed my lips greedily—a small beast awakened. Irina unbuttoned my shirt and stroked my abs.
