As I watched, he suddenly stiffened and kissed her even harder, sticking his tongue as far down her throat as he could. His hips jerked a bit and I actually saw a string of cum shoot up to land on his chest which he promptly brushed onto her body. She let out a short yelp and used her hand to catch the other squirts of cum.
After he was done, she didn't know what to do with her handful of jizz and I guess he told her to eat it because she lifted her hand to her mouth and licked it off. She still had his dick in a death grip and was giving it tugs. However, he was clearly shrinking and didn't look like it was going to respond so she let go after a while.
A while later he left and she walked back to our table, totally unaware of a big cum stain on her chest and also a dry streak on her forearm. We "innocently" asked her what she'd been doing, but she feigned ignorance. Soon she called her (future) husband and he showed up. She commenced kissing and hugging him transferring the other guy's sperm and saliva onto him. Watching them closely, I saw her rubbing his crotch and trying to give him the same handjob treatment through his pants. Where the other guy had 4 inches sticking out past his belt, her husband only had 4 inches total so she had to grip it through his pants. He also started kissing her neck and sucking her tongue unaware that it was covered with another man's saliva.
A few weeks later when she finally admitted to what I witnessed, she told me something funny. She never meant to give the tourist a handjob, but was tricked into it when he put her hands on his stomach. She was just rubbing his torso when she felt something pushing up from his pants. Confused, she grabbed hold of it and felt it grow before realizing what she held. The size and weight of the dick excited her so much that she loved squeezing and jerking it, but she had no wish to fuck it. She compared it against her body and said there was no way it would fit in her. However, after this whenever she got drunk she'd go around tugging on white guys dicks hoping to find large ones. Almost every expat at our old regular bar had gotten handjobs from her.
