Pic #17 did it for me. She's kneeling on the corner of the bed.you have good hard on, hands on her hips, foreskin halfway back and ready to roll. As you enter her your foreskin gets pulled right back and the head of your cock grows by about 20%. A delicious ejaculation will almost certainly follow!
I had a very nice session with my wife this morning. She knelt down on the corner of the bed and I enjoyed myself with a delicious palm pussy before entering her for the last few strokes. Inspiration was pic 17!
The pic of his erect cock behind her made me think if his foreskin could role back and expose his glans, it seemed a narrow opening of the foreskin for that big glans, but it really went backwards and he surely felt an awesome pleasure when he penetrated her and rubbed his exposed glans in her ass
