Covertly give her another load

You agree to pull out but have the plan to nut in her again. You practiced on an old girlfriend a technique where you'd cum but continue fucking her and then by the time your ready to nut again thats when you'd pull out and give her the nut she was expecting. You took her in every position you could think of and could do in the field, when you had her ride you cowgirl thats when you gave her baby batter #2, you continued to whale on her a while after and then pulled out and blew it all over her tramp stamp, you then put her dress back down, making sure it stuck to your load, she felt this too and looked angry. Your response was that the back of her dress is caked in mud anyway so noone will know, she seems to buy that so the two of you head back.
