A good friend of mine starting writing to my gf in whatsapp and the topics got more sexual by time (she tells me from time to time what they are writing)...
One day he seemed really horny and sended her a pic of his hard cock... She really seems to like it and told him she wants to suck it. Since then they are exchanging nude pics when they are horny without me knowing what exactly they send..
Makes me so incredible horny. Unfortunatley he lives far away and we dont see him often ...
