Just standing there, naked, stroking my stiff cock.

I was on my apartment balcony admiring the two curvy, shapely older ladies sunbathing naked in next door's garden. 

Both women were watching me, as they had the previous three days.

Soon I increased my stroke rate, needing to ejaculate.

The women watched intently as I spurted my cum, then called out, "Tomorrow?"

I just nodded in answer.
