Is This Possible?!?! 10 Pts best answer!?

Okay, so my 14 year old friend gave a handjob to her boyfriend and he ejaculated.15 minutes later, i walked over to pick her up. She touched me on my thigh and arms before being able to wash her hands. I might have touched the areas, but i didn't touch my vagina. I had shorts on and underwear and I just had my period. From my thighs, the sperm can't swim upwards and enter the vagina, right? Is there any possibility at all of being pregnant?
