Sure you have time to stretch

You begrudgingly agree, Courtney breathing a sigh of relief at that and thanking you enthusiastically. You watch intently as she begins contorting her lithe, toned physique in different ways, getting both a good stretch and showing off her well trained curves. Eventually she lays on her back, beckoning you over.

"Hey anon, can you come here a sec? I need your help stretching my hamstrings." She raises a thick leg into the air to accentuate the point.

Your breath catches in your throat at that, both from her beautiful fit body and from the knowledge that your throbbing erection will be impossible to hide from her. You can feel all three inches of virgin meat straining against the confines of your shorts, trying to desperately grow just a little bigger. Knowing you can't just say no now, you get up, trying to walk as casually as possible towards her. Hopefully the front on perspective will hide your micro tent. Courtney isn't looking at you anyway, instead looking up at the sky and waiting. You get over and begin helping her stretch, one hand on her ankle and the other on the back of her thigh. She feels so warm and strong, and your cock begins to leak precum like a broken faucet. Your heart races as you hear her gently groan from the exertion, and as you count to 15 you release, moving to her other leg. As your cock pulses with each heartbeat, it rubs up against the fabric of your underwear, sending waves of pleasure through you, and just as you reach 15 you lose control of yourself, having a hands free orgasm in your shorts.

Not only is your cock small, your loads typically are too, yet the close proximity to Courtney must have spurred your pathetic balls to release everything they have, resulting in a cumshot slightly stronger than the average man. Still nothing impressive, but by your standards an absolute fountain, and more than enough to soak through your grey shorts. Panic washes over you as you back away, looking down at the quarter sized wet spot of your cock. Courtney looks up to thank you, the words catching in her throat as she sees your tent and stain.

"Did... Did you just jizz your pants?" She quickly pulls herself to her knees, now eye length with your little wet bulge. "Holy shit did you cum just from touching me?" Her voice is filled with disbelief, and she looks up to you disgusted.

Face bright red you try to defend yourself, but after stammering for a moment, you meekly say, "It's uh, it's been a while since I..."

She gives a bark of laughter at that. "What like 19 years? Holy crap I can't believe this!" Though she still looks shocked there's a definite grin on her face. "I don't know if I should be impressed I'm hot enough to make you do that or sad that your that pathetic."

Covering your bulge you can't even look her in the eye, just pitifully apologizing to her.

Her voice sounds a little disappointed. "I'm not sure how you can run like that. Maybe we should just reschedule?"
