My friend and were having an outercourse or called dry humping. I am completely nude and she had only her panty on. There was no contact to her vaginal part directly. We had some penetration type of action through her panties but not direct penetration. She has become wet and because of her fluid her panty near vaginal part is wet. I'm pretty sure I had not touched her vagina with penis directly . But only slight penetration through clothes not to deep only light penetration. And I'm confident that I haven't ejaculated near her vagina and never ejaculated when we are having outercourse . There are no signs of pre cum too when I'm having with her. Now her period is delayed by 3 days. She is I'll for about 3 days 15 days back from this day and she takes a bit heavy stress as she thinks a lot. Why her period has been delayed is she pregnant ( because I had penetration through clothes and no precum type things on penis ) or any other signs like stress or illness made her get late periods? . Please reply back ASAP .
