In a dimly lit room, a new strap-on user, heart pounding with anticipation, lubes up the substantial dildo, marveling at its size and detail. Kneeling on all fours, they guide the head to their waiting hole, gasping at the initial penetration. Slowly, they push back, taking more of the toy, the smooth silicone filling them completely. The sensation is overwhelming, a mix of fullness and pleasure as they start to move, fucking themselves with increasing urgency, the dildo sliding in and out, their bodies covered in a sheen of sweat, their moans filling the room.
